1.1.1Basic System Components
The Isolera system is a high-performance flash chromatography system, consisting of the following
integrated components:
•A touch screen display, which is a solvent-resistant, color LCD screen with a resolution of
800 x 600 pixels. It serves both as a display and as the system’s input device via on-screen
touch controls.
•A fraction collector, which collects fractions into a wide variety of collection racks and vessels.
•A pump module, which directs liquid flow through the system. A default flow rate is specified
for each cartridge but, if desired, the flow rate can be changed. If the flow rate is increased,
the system will start the run at the default flow rate and then regulate towards the flow rate
defined in the method. Note that the system regulates on both flow rate and pressure. If
90% of the maximum allowed pressure is reached before the defined flow rate, the flow rate
at 90% pressure will be used.
•An internal detector, which provides the system with information on the light absorbance of
the solvents and samples passing through the detector flow cell. (It is also possible to
connect an external detector, e.g. Biotage ELSD-1080.)
1.1.2System Configurations
There are four system platforms available: Biotage Isolera Prime™, Biotage Isolera™ One, Biotage
Isolera™ Four, and Biotage Isolera™ LS (Large Scale). The differences are listed in the table below.
Flow Rate:1 to 100 ml/min1 to 200 ml/min1 to 200 ml/min50 to 500 ml/min

* An Isolera Prime system can be upgraded to and Isolera One or Isolera Four system.
An Isolera One system can be upgraded to an Isolera Four system.
†
One collection tray is standard, but by expanding the fraction collector, it is possible to use two
collection trays (see Figure 1-1) at the same time. The maximum collection volume (with no rack
change) is then 9600 ml instead of 4800 ml (with the 480 ml bottle rack). These systems are called
EXP systems (Isolera One EXP and Isolera Four EXP).
‡
The internal detector is available in three models: 1) 200-400 nm (variable UV detector), 2) 200-800
nm (UV-VIS), and 3) 254 nm (fixed UV detector). Note that the UV-VIS detector is not available with
Isolera Prime and the fixed UV detector is not available with Isolera LS.

1.1.5Accessories
Cartridges
The Isolera system is designed to operate with Biotage SNAP™, Biotage SNAP Ultra™ and Biotage
ZIP™ cartridges, which have easy-to-use Luer-lok™ connections. FLASH+
cartridges can also be used but may require tube adapters and a separate ring stand.
All SNAP and SNAP Ultra disposable cartridge components are made from materials meeting USP
Class VI specifications, which minimize organic extractables providing cleaner fractions.
SNAP cartridges are available packed with silica (KP-Sil), high-performance silica (HP-Sil), C
C18-HS), or NH (KP-NH) media. SNAP 750g and 1500g are available packed with silica (KP-Sil), C
(KP-C18-HS), or NH (KP-NH). Biotage ZIP cartridges are all packed with silica (KP-Sil).
SNAP Ultra cartridges deliver double the purification capacity of other flash cartridges by utilizing

Note that SNAP and SNAP Ultra 10g to 30g and Biotage ZIP 5g to 45g cannot be used on Isolera LS,
and SNAP 1500g is not recommended for use on Isolera Prime, Isolera One, or Isolera Four. SNAP
750g, Flash 75S, Flash 75M, and Flash 75L are not recommended for use on Isolera Prime.
Sample Loading Methods for SNAP and SNAP Ultra Cartridges
Biotage SNAP and SNAP Ultra cartridges offer several types of loading techniques including three
internal dry loading options.
Liquid Loading
Liquid samples can be:
•Injected into the SNAP or SNAP Ultra cartridge inlet Luer fitting using a syringe or, when using
an Isolera LS system, the sample loading pump.
•Loaded onto the frit using a pipette (not possible when using SNAP 750g or 1500g).
Samples should be dissolved at the highest concentration in the weakest solvent. Use of a strong,
polar solvent will compromise purification efficiency.
Internal Dry Loading
If internal dry loading is to be used (not possible with SNAP 750g and larger cartridges), the
cartridge insert must be removed. Internal loading can be achieved using:
•Prepacked Samplet
Prior to insertion, the solvent should be evaporated in open air or in vacuum. Prepacked Samplet
cartridges are available in the same media types that are available for the cartridges.
•Empty Samplet cartridges.
If media other than those available in prepacked Samplet cartridges is required (e.g. scavenger
or catch-and-release resin, or other media), it can be easily packed into empty Samplet
cartridges.
•Bulk loading.
Dried, preadsorbed sample on media is added directly to the top of the cartridge. Specific media
amounts are required; see the documentation supplied with the cartridge.
External Dry Loading
Dried, preadsorbed sample on media can be loaded externally using a DLV-030, DLV-070, DLV-500
(for SNAP 750g and larger cartridges). They all attach directly to the SNAP
inlet Luer fitting; DLV-500 uses a tube connection. For further information, see the user
documentation supplied with DLV-30 and DLV-70 (P/N 413107), and DLV-500 (P/N 412625).

Sample Loading Methods for Biotage ZIP Cartridges
Liquid samples can be injected into the Biotage ZIP cartridge inlet Luer fitting using a syringe or,
when using an Isolera LS system, the sample loading pump.
Dried, preadsorbed sample on media can be loaded externally using a dry load vessel (DLV-030 or
DLV-070).

Biotage ELSD-1080 Detector
ELSD-1080 (evaporative light-scattering detector) is a universal detector designed for use with
Isolera One and Isolera Four systems when purifying compounds with little or no UV absorption
such as carbohydrates, steroids, lipids, and terpenes.
ELSD-1080 provides intelligent method design which enables the chemist to independently set
nebulizer and evaporator temperatures for a particular compound or compound class. Independent
temperature control helps ensure that all compounds are detected.

Status and Task Field
The system can be idle, paused (), or processing (). When the system is processing, the
following tasks can be in progress:
• UV ON: The system turns on the detector lamp(s).
• Eq. Flush: Before an equilibration is started, the system runs an equilibration flush to empty
the solvent inlets of solvents used in the previous purification and fills them with new solvents.
411829-L, Description and SpecificationsApril 2012Page 1-9
Page 16
• Equilibrating: The system is running an equilibration.
• UV Warm-up: The UV lamp is being warmed up. This takes approximately 7.5 minutes.
• UV Zero: The system is setting the UV zero level.
• Baseline Det.: The system is measuring the solvent absorbance of the gradient so that the
maximum solvent absorbance spectrum can be subtracted from the signal presented by the
detector during the gradient run. For more information on baseline correction, see “Specify
Collection Parameters at the Collection Tab” on page 4-8. (Only available on systems with a
Spektra license installed.)
• Gradient Flush: After a performing a baseline detection, the system flushes the system with
the solvent mix used in the start of the gradient.
• Sample Pump: The sample pump is in use. (Only available on Isolera LS.)
• Gradient: The system is running a purification. If the system is collecting on the tray, the
background color is green. If fractions are collected through the waste channel (i.e. the
Bypass Tray option is enabled), the background color is magenta.
• Line Flush, Air Flush, Purge, and Detector Flush: After the gradient purification stage is
completed, the system performs enabled flushes (in the System mode) and a system
decompression process (Purge). It is also possible to manually instruct the system to perform
an Air Flush and a Purge. Note that the Air Flush feature is not available with Isolera Prime.
• Prime: The system is priming the solvent inlet(s).
Buttons in the Right-hand Panel
The following buttons are available in the right-hand panel:
• Main Menu: Go to the main menu to enter the Data Administration mode, enter the System

• Create a new method. If using the method wizard, it will guide you step-by-step through
the setup of a run. You can also use the TLC to Linear Gradient editor or the TLC to Step
Gradient editor (requires a Spektra license) to calculate a purification gradient and get
cartridge and sample load recommendations. After setting up the method, you can save it by
entering a unique method name.
• Base the new method on an existing method. You can either base the method on one of
the preconfigured Biotage methods or a method created and saved in the system’s database,
on a USB memory device, or in a share folder on the network. After editing, you can save the
method under a new name by entering a unique method name. The original method remains
unaltered under its original name.
• Base the new method on a previous purification (at the Results tab). After editing the
purification parameters, you can save it by entering a unique method name.
NOTE
You do not have to save your method to be able to run it.
1.2.6Status Tab (Chemistry Mode)
At the Status tab, in the software’s Chemistry mode, you can:
• View information on a cartridge mounted on the system. Available information is: user,
sample name, status, allocated rack(s), and the estimated time when the system will have
completed the purification.
• Enable injection of a liquid sample using a syringe or the sample loading pump (the Load

1.2.7Results Tab (Chemistry Mode)
Purifications that are processed on the system are stored as individual records in the system’s
database. The records can, if desired, be saved by the user as XML files (text files including all raw
data) on a USB memory device or in a share folder on the network.
At the Results tab, in the Chemistry mode, it is possible to search and view the results of all
purifications stored in the system’s database, on a USB memory device (if connected), or in a share
folder on your network (if connected). Two result reports are available for each purification: 1) an
archive report with purification details, a chromatogram, a 3D absorbance spectrum for the whole
detector range (requires a Spektra license), TLC data (if entered in the TLC to Step Gradient editor)
and 2) a fraction report. These reports can be printed to a network printer with postscript support
or a local USB printer and saved as PDF files on a USB memory device or in a share folder on your
network.
At the Results tab, it is also possible to create a new method with the same purification
parameters as the ones used in a previous purification. If desired, the system can help you to
optimize the gradient to isolate one of the peaks and reduce the amount of solvent used.

1.2.8Solvents Tab (Chemistry Mode)
At the Solvents tab, in the software’s Chemistry mode, you can:
• Assign a solvent to each of the solvent inlets on the right side of the system. When a
purification is run, the software references the solvent assignments to determine which
solvent inlets that are connected to the solvents used in the method. Therefore, it is
important that the solvents be assigned accurately. If you change the solvent that is
connected to a particular inlet, you must make the corresponding change in the software.
To assign a solvent, press the applicable Solvent text box.
• Enter the capacities and current fluid levels for the waste and solvent reservoirs
each time you empty a waste reservoir or replenish a solvent. The system will issue a
warning when it is time to replenish a solvent or empty a waste reservoir. To enter values,
press the applicable text box. (This feature is only available if the monitoring of solvent and
waste are enabled, see “Enable or Disable Monitoring of Reservoirs” on page 3-9.)
• Prime the solvent inlets to 1) remove any air bubbles from the pump and solvent inlets by
flushing them with solvents or 2) empty the solvent inlets of solvents used in the previous
purification and fill them with new solvents.
• Flush a cartridge with air to empty it of remaining solvents before unloading it. This
feature is not available with Isolera Prime.
• Purge a cartridge to release any remaining pressure before unloading it.
• Control the sample loading pump when cleaning the pump tubing or emptying the tubing
of solvent and/or sample before replacing it. (Only Isolera LS is equipped with the sample
loading pump.)

Name: The user name will be used in the various user name selection boxes as well as in the
purification records. The user name is typically the person’s name, initials, employee number, etc.
Password: It is possible to password-protect a user account. The password will be used when
saving a method and, for users with system owner privilege, when entering the Data Administration
and System modes.
E-mail: If the system is connected to your network and the Auto Send Reports option is enabled
(see page 3-8), an e-mail with a result report will be sent to the e-mail address specified in the
user’s account when a purification has been completed. An e-mail will also be sent to the user when
user interaction is required, e.g. when a rack has to be replaced, a solvent needs to be replenished
(if monitoring is enabled), a waste reservoir needs to be emptied (if monitoring is enabled), and a
leak is detected (if using Biotage Leak Detector).
Privilege: A user can have chemist or system owner privilege:
• The chemist privilege gives the user access to the Chemistry mode, i.e. the user can set up
and run purifications, and view results.
• The system owner privilege gives the user both the chemist privilege (see above) and access
to the Data Administration mode (the user can administrate cartridge types, methods, rack
types, results, solvents, and user accounts) and to the System mode (the user can change
detector, network, reporting, and runtime settings, set the system clock, calibrate the touch
screen, fraction collector, and internal detector, perform an intensity scan of the internal
detector, release stuck check valves, back up and restore the database, export the system

3.6.2Enable or Disable Automatic Rack Allocation
If automatic rack allocation is enabled, racks or vessels (depending on the selected method) are
automatically allocated one at a time as they are needed. The collection area must therefore at all
times be loaded with racks in all positions.
Two automatic rack allocation methods are available:
• Automatic: The system allocates racks in sequence, starting with rack A, then B, and so
forth. With this allocation method, the collection tray can be shared by several runs with the
same rack type but a single rack cannot be shared by several runs.
411829-L, System SettingsApril 2012Page 3-8
Page 45
3
• Automatic Vessel: The system allocates vessels in sequence, starting with the first vessel
in rack A, the second in rack A, and so forth. With this rack allocation method, racks can be
shared by several runs but the collection tray cannot be shared by several users.
When enabling automatic rack allocation on an Isolera Four system, the following rules also apply:
• All racks on the collection tray must be of the same type. The rack type to be used is
decided by the first purification that is queued up.
• Allocation only when needed. No rack or vessel allocation is performed when a
purification is queued up. When the run is started racks or vessels are allocated one at a time
as they are needed.
• Always replace all racks when asked to. If the system runs out of vessels, you will be
asked to replace all racks in the collection area at the same time (even if some of the racks
have been used by previous runs).
To enable or disable automatic rack allocation:
1. Select the Runtime tab in the right-hand panel.
2. Select the Rack Allocation Mode text box.
3. To enable automatic rack allocation, select Automatic or Automatic Vessel.

1. Select the Runtime tab in the right-hand panel.
2. Select the Solvent Monitoring and/or Waste Monitoring text box and select No.
3.6.6Enable or Disable Run Requirement Estimation
If you enable vessel, solvent, and waste estimation, you will be informed (when allocating the
cartridge and rack positions) if a sufficient quantity of vessels is allocated, if a sufficient quantity of
the correct solvent is present in each solvent reservoir, and if the waste reservoir has sufficient
capacity for the run.
To enable or disable vessel, solvent, and/or waste estimation, select the corresponding text box and
select Yes or No. If using an Isolera Four system, ensure to select the number of waste reservoirs
to be used in the Waste Reservoir text box. The waste can either be pooled into a single waste
reservoir (insert all four waste outlet tubes into a single waste reservoir) or collected in four waste
reservoirs (insert each waste outlet tube into a single waste reservoir).
3.6.7Specify How Flushes Are Performed
At the end of a purification, i.e. after the gradient purification stage is completed, the system
performs a:
• Line Flush: The system flushes the inlet line and the cartridge with 9 ml (when using an
Isolera Prime, Isolera One, or Isolera Four system) or 20 ml (when using an Isolera LS
system) of the specified solvent or solvent mix.
• Air Flush: The system flushes the inlet line and the cartridge with air and a small amount of
the specified solvent or solvent mix. The flush volume depends on the cartridge type.
Air Flush is optional. This feature is not available with Isolera Prime.
• Detector Flush: The system flushes the detector with 27 ml (when using an Isolera Prime,
Isolera One, or Isolera Four system) or 45 ml (when using an Isolera LS system) of the
specified solvent or solvent mix.
To change the flush settings:
1. Select the Runtime tab in the right-hand panel.
2. To enable or disable the line flush, select the Line Flush text box and select Collect (the line
flush will be collected on the collection tray), To Waste (the line flush will be sent to waste), or Off (no line flush will be performed).
3. To enable or disable the detector flush, select the Detector Flush text box and select Collect
(the detector flush will be collected on the collection tray), To Waste (the detector flush will be
sent to waste), or Off (no detector flush will be performed).
NOTE
If the automatic line flush is disabled, ensure to prime the cartridge flow
path before each run.
We recommend that the detector flush is kept enabled. A dirty detector
flow cell has decreased transmissivity, which causes increased noise level,
decreased response, and difficulties performing UV Zero.

4.3 Control the UV Lamp
The internal detector uses an ultraviolet (UV) lamp and, if using the UV-VIS detector, a tungsten lamp in
its detection process. The UV lamp must be warmed up in order for the signal to be accurate and stable.
NOTE
The UV lamp should be turned on 7.5 minutes before starting a purification
so the UV lamp can reach operating temperature.
The lamp(s) is/are automatically turned on when:
• The Isolera system is switched on.
• The user enters the Chemistry mode (i.e. press the Chemistry button in the main menu).
• The user starts a run (i.e. press the button in the Run Parameters dialog). However, before
starting the run, the software waits (approximately 7.5 minutes) for the UV lamp to warm up.
You can also turn on the detector lamp(s) manually by pressing Turn Lamp On in the right-hand
panel. By doing this ahead of time, you can avoid the delay that is required if the software turns the
lamp(s) on at the start of a run.
To prolong lamp life, the lamp(s) is/are turned off automatically if the system is idle (no purification
is started and no user interaction is detected) for approximately two hours.
Bypass the Automatic UV Lamp Warm-up Period
You can bypass the automatic UV lamp warm-up period by pressing Skip Warm Up in the right-
hand panel. However, if the UV lamp has not reached operating temperature, purification results
may not be optimal.

Create a Gradient at the Gradient Tab
NOTE
If you want to calculate the gradient from TLC data, see page 4-10.
Isolera One, Four, and LS have four solvent inlets (A, B, C, and D) while
Isolera Prime has two (A and B).
1. Select the Gradient tab.
2. The gradient can be set up using the gradient table and/or the gradient graph. To show or hide
the gradient table, press the Table button ( = gradient table is shown).
3. In the graph, the X-axis indicates the length and the Y-axis indicates the percentage of Solvent B
(if a blue gradient line), Solvent C (if a yellow gradient line), or Solvent D (if a green gradient
line) in the solvent mix. To change the length unit, press the Unit button repeatedly until the
desired unit appears; CV (Column Volumes), milliliter, or minutes. CV is the default unit.
4. If you want to equilibrate the cartridge before the run, press Equil. ( = equilibration is
enabled). The default equilibration length is 3 CV (3 to 5 CV are recommended for full
equilibration).
5. To add a gradient segment, select a segment in the gradient table or the graph (see Figure 4-2)
and press Add. The new segment will be added after the selected segment.
6. To add a gradient segment with Solvent B ( ) and Solvent C ( ) and/or with Solvent C and
Solvent D ( ), press B/C and/or C/D. The new segment will be added at the end of the gradient.

Specify the Method Parameters at the Parameters Tab
1. Select the Parameters tab.
2. Select the User text box and select your user name. If you have not been assigned a user
name, please contact your system supervisor.
3. Select the Cartridge Type text box and select the cartridge type to be used. If you do not want
to use the default flow rate and/or equilibration flow rate for the cartridge type, select the
corresponding text box and enter the desired flow rate. See Table 4-3 on page 4-21 for
recommended flow rates. The maximum flow rate that can be used depends on:
• the maximum fill rate(s) defined for the used solvent(s) in the Data Administration mode,
and
• the maximum dispense rate of the system (200 ml/min for Isolera Prime, One and Four,
and 500 ml/min for Isolera LS) or, if using an external detector, the maximum dispense
rate defined for the external detector in the System mode.
411829-L, OperationApril 2012Page 4-4
Page 55
4
As a single-piston pump only delivers liquid during the dispense stroke, the maximum flow rate
when using an Isolera Prime system is equal to (Max Fill Rate x Max Dispense Rate)/(Max Fill
Rate + Max Dispense Rate).
80 ml/min and you use a external detector with the maximum dispense rate of 100 ml/min, the
highest flow rate that can be used is (50x100)/(50+100)=33 ml/min. If the external detector is
disabled, the highest flow rate that can be used is (50x200)/(50+200)=40 ml/min.
If small test tubes are to be used, ensure to adjust the flow rate so that no
splashing will occur when fractions are collected.
4. Select the Rack Type text box and select the rack type to be used; see Table 4-1 on page 4-7
for guidance. If you do not want to use the default max fraction volume for the vessel type
and/or the default dispensation order (S-pattern), select the corresponding text box and
change the setting. The software prevents you from entering a fraction volume that will
overflow the vessels.
5. Select the solvents to be used by selecting the corresponding text box in the Solvents field.
(They should be the solvents determined by the TLC procedure.) To show all solvents, press
Show All. To only show the solvents connected to the system, press Show Connected. Note
that the solvent percentages are specified at the Gradient tab.
For reversed-phase purification with methanol and water, it is strongly
recommended to premix the water with 5% of methanol and degass either
through vacuum or sonication. Degassing of protic solvent blends
decreases out-gassing of entrapped air during gradient elution, which will
impact gradient performance and flow rates.
Examples: If the fill rates for the used solvents are 50 ml/min and
WARNING
NOTE
If automatic rack allocation is enabled, all racks on the collection tray must
be of the same type. When using an Isolera Four system, the rack type to
be used is decided by the first purification that is queued up. Any
purification queued up after that must use the same rack type. To change
rack type, wait until all present runs are finished and then remove them at
the Status tab.

Specify Collection Parameters at the Collection Tab
1. Select the Collection tab.
2. Select the Source text box and select a detection mode:
• UV1+UV2: Control the collection and fractionation using both wavelength channels.
Possible collection and fractionation parameters are Collect All, Start Threshold, Slope,
Shoulder, and Valley. (Only available if you have the variable or the UV-VIS detector.)
• UV1: Control the collection and fractionation using one wavelength channel. (If you have
the variable or the UV-VIS detector, channel 2 is used for monitoring of the run.) Possible
collection and fractionation parameters are Collect All, Start Threshold, Slope, Shoulder,
and Valley.
• λ-all: The system uses average absorbance within a user-defined range for collection and
fractionation. Possible collection and fractionation parameters are Collect All, Start
Threshold, and Valley. (Only available on systems with a Spektra license installed.)
• Manual: Control the collection manually; enabling or disabling Collect All.
• External: Control the collection and fractionation using an external detector (e.g. an
Biotage ELSD-1080 detector). Possible collection and fractionation parameters are Collect
All and Start Threshold.
3. If you want the system to perform baseline correction, turn on the Baseline Correction
option. (Only available on systems with a Spektra license installed.)
If this option is turned on, the gradient run is preceded by a short solvent light absorbance
detection phase. During this phase, the light absorbance of the used solvents is measured at all
wavelengths that will be used for collection and fractionation (UV1, UV1+UV2, or λ-all). The
measurement results in a baseline containing the maximum absorbance of the solvent system at
each wavelength used, a solvent absorbance spectrum. During the gradient run, the maximum
solvent absorbance spectrum is subtracted from the signal presented by the detector.
4. If you have the variable or the UV-VIS detector, enter the wavelengths to be used for channel 1
(UV1) and channel 2 (UV2) by selecting the corresponding text box. The possibility to set
these wavelengths can help optimize compound detection since a compound’s absorption of
light varies with the wavelength.

Replace and Allocate Racks During the Run
If more fractions are to be collected than can fit in the allocated rack(s), the system pauses, the
collection arm returns to the home position (the inner right corner), and the Load New Racks
dialog opens. Replace the rack(s) according to the dialog and press the Resume button to resume
the run. The collection is resumed in the first vessel in the lowest lettered rack. For example, if
racks B and C are allocated for the run, the collection is resumed in rack B in vessel 1.
You can at any time allocate free rack positions by pressing Edit... at the Status tab. (This is not
possible if automatic rack allocation is enabled.)
NOTE
When using an Isolera Four system with automatic rack allocation enabled,
you have to replace all racks in the collection area at the same time when
asked to (even if some of the racks have been used by previous runs).
Auto-Extend Mode
If the system is collecting fractions and remaining light absorption is detected when the system
nears the end of a purification, the system enters the Auto-Extend mode (if enabled in the system
mode). This extends the gradient purification stage of the run with 25% of the total gradient length
using the final conditions in the method.
Line Flush, Decompression, and Detector Flush
After the gradient purification stage is finished, the system performs a line flush (if enabled), air
flush (if enabled), system decompression, and a detector flush (if enabled). To enable or disable
flushes, specify whether enabled flushes are collected or not, and specify which solvents to use for
the flushes, see “Specify How Flushes Are Performed” on page 3-10. Note that the Air Flush feature
is not available with Isolera Prime.

4.11.3 Prime the System
Before you start a purification on your Isolera system, you might need to prime the solvent inlets to:
• Remove any air bubbles from the pump and the solvent inlets by flushing them with solvents.
• Empty the solvent inlets of solvents used in the previous purification and fill them with new
solvents.
WARNING
Never prime the Isolera system without a cartridge mounted on the
system or without the cartridge’s inlet and outlet tubing coupled together.
To avoid leakage, check all tubes and fittings before priming the system.
NOTE
All solvent inlets must be primed with solvent to achieve the specified
pump performance.
To prime the system:
1. Ensure that a sufficient quantity of the solvent(s) you want to use is present in the solvent
reservoir(s) and the waste reservoir has sufficient capacity for the prime.
2. Select the Solvents tab in the right-hand panel.
3. Ensure that the solvents are assigned accurately to the solvent inlets at the Instrument Solvents tab. If the capacity and current volume values are available for the waste and/or
solvent reservoirs (i.e. the monitoring of levels is enabled), check that the values are correct.
To make changes, see “Assign Solvents to the Solvent Inlets” and “Set the Reservoir Volumes”
on page 4-32.
4. Select the Prime tab.
Figure 4-27. Prime Tab (Isolera Four Shown)
5. If using an Isolera Four system, select the Channel text box and select the cartridge position
and waste reservoir to be used.
6. Select the Path text box and select the prime path. If you do not want to prime the cartridge,
press Bypass.
7. If you selected the path With Cartridge, select the Cartridge Type text box and select the
cartridge type mounted on the system.
8. Select the Volume text box and enter the total prime volume.
If you want to fill a solvent inlet with a new solvent, we recommend that you prime with at least
40 ml (when using an Isolera Prime, Isolera One, or Isolera Four system) or 50 ml (when using
an Isolera LS system) of that solvent. If you also want to fill the liquid lines from the pump to
411829-L, OperationApril 2012Page 4-33
Page 84
4
the (selected*) waste valve with the same solvent, we recommend that you prime with at least
60 ml when using an Isolera Prime, Isolera One, or Isolera Four system or 100 ml when using
an Isolera LS system.
9. Select the Flowrate text box and enter the flow rate. The maximum flow rate that can be used
depends on:
• the maximum fill rate(s) defined for the used solvent(s) in the Data Administration mode,
and
• the maximum dispense rate of the system (200 ml/min for Isolera Prime, One and Four,
and 500 ml/min for Isolera LS) or, if using an external detector, the maximum dispense
rate defined for the external detector in the System mode.
As a single-piston pump only delivers liquid during the dispense stroke, the maximum flow rate
when using an Isolera Prime system is equal to (Max Fill Rate x Max Dispense Rate)/(Max Fill
Rate + Max Dispense Rate).
80 ml/min and you use a external detector with the maximum dispense rate of 100 ml/min, the
highest flow rate that can be used is (50x100)/(50+100)=33 ml/min. If the external detector is
disabled, the highest flow rate that can be used is (50x200)/(50+200)=40 ml/min.
10. Enter the percentage of each solvent connected to the system that shall be used in the prime.
If using an Isolera LS system and a solvent inlet line is empty or filled with air bubbles, you
should prime it separately. (If several solvents are listed and you only want to use one solvent,
enter “100” for the solvent that you want to use and enter “0” or press Clear for the other
solvent(s).)
11. To start priming, press Start.
*When using an Isolera Four system.
Examples: If the fill rates for the used solvents are 50 ml/min and

5.3 Spare Parts
A list of spare parts is available at www.biotage.com.
5.4 Clean the Exterior of the System
Regular cleaning of the touch screen, if performed properly, extends the touch screen life and
protects it from contaminants that cause unnecessary wear. Always turn the system off before
cleaning the screen.
WARNING
When cleaning the touch screen, use only non-ammonia based window
cleaner and do not apply the liquid directly to the screen as this could
introduce liquid into the screen electronics section, which could damage
electronic components.
NOTE
Avoid harsh cleaners and chemicals, and getting moisture inside the system.
1. Shut down the system as described on page 4-1.
2. Disconnect the power cord from the power outlet.
3. To clean the touch screen, wipe with a clean, non-abrasive, dry cloth. If this does not clean the
screen properly, then you may apply a small amount of non-ammonia based window cleaner
to a clean, non-abrasive cloth and then wipe the screen with the damp cloth. The cleaning liquid
must be applied to the cloth only. After cleaning, wipe dry with a clean, non-abrasive cloth.
4. To clean the exterior of the system, clean the surfaces using a clean, lint-free cloth, lightly
dampened with water. If required, a small amount of mild soap may also be used. After
cleaning, wipe dry with a clean, lint-free cloth.
5.5 Implement a Mobile Phase Change
To avoid faults during a mobile phase change, it is necessary to perform the change throughout the
entire chromatographic system (i.e. in the reservoir, pump, injector, column, and detector). The
procedure is to fill and flush the system, using the prime function (see page 4-33), with a series of
mutually miscible solvents until a gradual change to the new mobile phase (solvent) is
accomplished. If this procedure is not observed, precipitation may occur not only in the detector
flow cell but also in other parts of the system. For example, to change from an organic mobile
phase to aqueous solutions, it is necessary to flush the whole system with acetone or an alcohol
(e.g. isopropanol).
5.6 Clean the Detector Flow Cell
WARNING
Ultraviolet (UV) light can injure your eyes. Do not operate the Isolera
system with the detector flow cell removed and the retaining latch open.
Keep the detector flow cell clean and protect it from dust and chemical spills. Particular attention
should be paid to preventing the flow cell from leaking.
A dirty cell has decreased transmissivity, which causes increased noise level, decreased response,
and difficulties performing both auto and manual UV Zero functions.
411829-L, MaintenanceApril 2012Page 5-3

6.4 Pump-Related Problems
NOTE
If using highly volatile (i.e. high vapor pressure) solvents such as
dichloromethane, reservoir elevation is strongly recommended. Use the
solvent tray at the top of the system. It is also highly advisable to reduce
the flow rate and, if possible, lower the ambient temperature. See “Solvent
Specifications” on page 1-19 for the vapor pressure of different solvents.

2000 hours, the message The detector lamp has been used for x hours and should be replaced appears at
start up.
If expected peaks do not show when you have the
Baseline Correction option turned on and are using
solvents that are high-absorbing over a wide range of
wavelengths (e.g. acetone, and toluene), try
performing the run without baseline correction.
Choose less absorbing solvent(s).
