Introduction

1 Introduction

The METTLER TOLEDO OptiMaxTM 1001 is a reactor system for performing synthesis with a 250-mL,
a 500-mL, or a 1000-mL glass reactor. The instrument is operated via the integrated touchscreen.
• The reactor can be heated or cooled and its content stirred and reuxed.
• The temperature of the reactor content can be measured using a Pt100 sensor.
• The integrated pH measurement system equipped with the appropriate electrode allows you to
measure the pH value of the reactor content.
• You can export the acquired data to another program for further processing using the USB Memory
Stick supplied.
We, Mettler-Toledo AG, accept no liability whatsoever if you do not observe the following rules
and measures for safe operation of the OptiMax™ 1001 with the glass reactor!

2 Safety Measures

The OptiMax™ 1001 has been tested for the experiments and intended purposes documented in these Operating Instructions. However, this does not absolve you from the responsibility of perform­ing your own tests of the product supplied by us regarding its suitability for the methods and purposes you intend to use it for. You should therefore observe the following safety measures.
Please comply with all safety and accident-prevention regulations, as in force for laboratory work!

2.1 Measures for your protection

Grounding of the power supply outlet
– Make sure you plug the power cable supplied into a power supply outlet that is
grounded! A technical fault could otherwise result in death or serious injury.
Risk of an elec-
trical shock
Risk of explosion

Risk of explosion
Power failure
– Implement appropriate measures like an uninterruptible power systems (UPS)
against possibly fatal consequences of a power failure!
Potentially explosive environment
– Never work in an environment subject to explosion hazards! The OptiMax
TM
1001 housing is not gas tight (explosion hazard due to spark formation, corro­sion caused by ingress of gases).
Critical reactions
– Always perform a safety analysis before starting investigations with a high haz-
ard potential, for example by a Differential Scanning Calorimeter!
Electrostatic charge formation through stirring of the reaction mass
Hazardous charges can build up in the reactor interior under the following condi­tions:
• when nonpolar liquids of high resistivity (>10
8
Ω.m) are stirred at high speed (i.e.
at high ow rates),
• with two-phase systems with suspended solids (e.g. after crystallization pro-
cesses in nonconductive solvents or immiscible liquids).
– We therefore recommend to work under an inert atmosphere (nitrogen or ar-
gon)!

Safety Measures
Risk of explosion
Risk of burns
Hand injury
Reactors
– Check the reactor periodically for damage (scratches, formation of cracks)!
Hot parts
– Do not touch the cover plate of the box, the xing ring, reactor cover and attach-
ments of the reactors or the overhead stirrer if you work at temperatures above 50 °C.
– The housing of the stirring motor may become hot.
Overhead stirrer
– Do not hold the rotation stirrer shaft or the coupling by hand when you operate
the stirrer motor! You could injure your ngers.

2.2 Measures for Operational Safety

Connection of cables
– Connect the cables of stirrers or sensors to their respective inputs and outputs
before you switch on the instrument, and do not disconnect a cable while the system is in operation! The printed circuit board of the instrument could other-

Caution
wise be damaged.
– Make sure that the power supply is easily accessible at any time.
Ventilation of the instrument
– Make sure the instrument is well ventilated! It dissipates a lot of heat especially
during longer heating periods and if the temperature difference between the temperature of the thermostat (Tj) and the temperature of the coolant (Tc) is large. If the temperature of the instrument is too high, its temperature protection device is activated, i.e. the instrument is switched off. After cooling down, you can switch it on again.
– Leave a free space of at least 10 cm between the ventilation slots at the back
side of the instrument and any other object or the wall.
Condensation of atmospheric moisture
– Purge the instrument with dry air, nitrogen or argon (3 L/min without purging the
reactor)! This prevents the ingress and condensation of atmospheric moisture and therefore possible corrosion of the instrument.

Caution
Safety Measures
Cooling
The instrument needs a constant ow of a cooling medium. You can use salt-free
tap water, ethanol, ethylen glycol or silicone oil.
– If the water is polluted or has a high degree of hardness, install a lter in the
inlet line and clean it regularly!
– Do not use the owmeter with any other liquids than water, the owmeter is not
resistant against other liquids than water!
Cooling with cryostats
– Do not use NaCl or CaCl
solutions! The high chloride concentration can lead
2
to corrosion of the heat transfer area of the instrument.
– Do not use the owmeter with any other liquids than water, the owmeter is
not resistant against other liquids than water! Connect any other cooling liquid directly to "Cooling In" without using the owmeter!
Thermal shock
Avoid any thermal shock in conjunction with the glass parts of the instrument.
– Never ll cool liquids into hot glassware and vice versa.
Caution

3.2.3 Connecting a Coolant

The instrument requires a constant ow of a cooling medium (see Section 2.2: "Measures for Opera­tional Safety: Cooling" and Chapter 10: "Technical Data").
1. Connection of a coolant
– Push one piece of the fabric tube (No. 51 161 187, ø 8/14 mm) over the cooling inlet of the
coolant owmeter, secure it with a hose clamp, and connect it to the coolant supply.
– Push a second piece of the PVC tube over the elbow coupling of the cooling outlet on the
back side of the instrument, secure it with a hose clamp and connect it to the waste water system.
Note:
Never use the ow indicator for the coolant nor the coolant owmeter for any other liquids than
water!
2. Connection of a cryostat
– Screw the insulated connection tubes directly onto the inlet/outlet connectors on the back
side of the instrument.
Caution:
Never use the owmeter for the coolant when using a cryostat, the owmeter is not resistant
against other liquids than water!

3.2.4 Connecting a Purge Gas

Caution Operation without purging the instrument can damage the instrument and will void
the warranty!
To prevent corrosion by condensed atmospheric moisture in the instrument, the instrument must be
purged with a dry gas, e.g. dried air, dried nitrogen or dried argon (see Chapter 11: Technical data).
– Install a PVC tube (No. 51 192 239, ø 4/10 mm ) on the purge gas inlet of the purge gas owmeter,
secure it with a hose clamp and connect it to the gas supply.
Note:
The "Purge In" and "Inert In" inlets on the back side of the instrument are directly connected to
the outlets on top of the housing via seperate lines and are thought for purging the stirrer housing
(Purge Out) or to feed the reactor with inert gas (Inert Out).

3.3 Installing the Overhead Stirrer

The overhead stirrer consists of
• the stirrer motor with already mounted chuck and clamping nut for fastening the stirrer shaft,
• a Alloy 22 stirrer shaft with pitched-blade stirrer elements in Alloy 22 for two-piece reactors or
• a borosilicate glass stirrer shaft with a PTFE half-moon stirrer blade for one-piece reactors,
• a PTFE adapter with sealing sleeve, compession spring and adapter loosening device,
(the loosening device is already mounted on the adapter)
• the locking device which secures the stirrer shaft.
PTFE Sealing rings
In case the stirrer adapter gets
stuck on the reactor cover, turn the loosening ring counterclockwise
until it pushes slightly against the ground joint. While carefully turn­ing it further, the stirrer adapter
wil come loose and can be taken
away.
Note:
In case you are using PTFE seal­ing rings between stirrer adapter
and ground joint, make sure you
always use two of them on differ­ent heights of the adapter to avoid tumbling of the stirrer!

–Push the stirrer shaft from below through the
opening of the reactor cover.
–Push the adapter loosening device over the stirrer
shaft.
–Push the stirrer adapter with the bearing sleeve
and the compression spring over the stirrer shaft and screw the loosening device bottom-up onto the adapter.
–Fasten the adapter with the bayonet coupling to
the stirrer motor.
– Push the stirrer shaft through the stirrer motor.
–Carefully check and adapt the height of the stirrer
shaft and the pitched-blade element with the reac­tor for an applicable immersion depth.
–Fix the stirrer shaft by tightening the chuck. and
secure it with the locking device on top of the chuck.
(The locking device prevents the stirrer shaft from
falling into the reactor in case the chuck is loos­ened uncarefully or by mistake.)
–Insert the adapter into the central opening of the
cover.
– Connect the stirrer cable to the connector on top
of the instrument housing.
To change the immersion depth of the stirrer shaft :
– Release the chuck while holding the stirrer shaft.
– Release the locking device and adapt the immer-
sion depth.
– Tighten the chuck and secure it with the locking
device.
Caution
Always check the stirrer for being mounted properly and not touching any sensors or other inserts before you let it run! The bearing sleeve has to contact the stirrer shaft tight-tting.
In case you encounter problems with a worn out bearing sleeve (as a result the stirrer shaft may no longer be tight) please replace the bearing sleeve (ME 51192163). An additional bearing sleeve
should always be kept in stock for replacement.

– Fix the reactor holder (ME 51 162 782) to
one of the lab bars and place the reactor in the reactor holder.
– Place the O-ring on the cover rim and
place the cover on the reactor.
– Place the clamp chain carefully around the
cover and the reactor anges.
– Screw the hook in or out so that the
buckle can be easily closed (with one
nger).
Note
Before you place the reactor in the thermo­stat, we recommend that you install the Tr
sensor and other inserts in order to check
their distance from the stirrer or the bottom of the reactor. We also recommend that you add the reagents and solvent for the starting
volume and possibly check the ll level of the rst ll. The Tr sensor must be immersed in the reaction solution to a depth of at least 1.5 cm for glass sensors or 2.5 cm for sensors made of Alloy 22 to give correct measure-
ment values.
METTLER TOLEDO OptiMax™ 1001 19
Installation
– Remove the assembled reactor from the
reactor holder and insert it into the thermo­stat.
– Attach the drain union (ME 51 162 685) to
the bottom drain valve and fasten it with the pinch clamp.
Caution:
Always remove the pinch clamp and the drain
union before removing the reactor from the thermostat!
The rotation lock
After you insert the reactor into the thermostat you should always lock it using the rotation lock - this
prevents the reactor from rotating concurrently while you open or close the bottom drain valve.
Push the blue rotation lock towards the reactor. Make sure the lower pin ts into the chain and holds it in place. (See the left picture below.)
The rotation device can also be used to lock the reactor in an uplift position. Uplift the reactor and lock it with the upper pin of the rotation lock. In this uplift position the bottom of the reactor can be observed through the reactor window. (See the right picture below.)

3.4.4 The bottom drain valve of the Two-Piece Reactors

The assembly of the bottom drain valve (which is used for the 500 mL and 1000 mL two-piece reac­tors) can be derived from the drawing on the next page. The drain valve is delivered already assembled. To open or close the valve simply turn the spindle in a way that its blue tip opens or seals the drain at the bottom of the reactor.
Caution The spindle has a strong spring integrated, which compensates expansion and contraction of the re-
actor materials caused by variations in temperature. At the same time it ensures a proper sealing of the drain. To retain the function of this spring and to avoid breaking of the reactor glass always close the bottom drain valve hand-tight and afterwards reopen it slightly (quarter to half a turn).
To disassemble the valve for cleaning proceed as follows:
1 Unscrew the spindle and pull it slightly back.
2 Loosen the pressure screw slightly and remove the spindle from the valve.
3 Loosen the pressure screw completely and put it aside. 4 Remove the pressure piece and the sealing ring. 5 After removing the insert ring, at last the connecting nut can be taken away.

3.5 Installing the 500 mL Two-Piece Reactor

The 500 mL two-piece reactor comes with the same reactor cover as the 1000 mL two-piece reactor.
Since the reactor itself is smaller than the 1000 mL reactor, you have to use a receptacle
(ME 51 162 670) for tting it into the thermostate (See chapter 3.5.1). In addition you need to use the smaller reactor holder for the 500 mL reactor (ME 51 162 783):
– Push the glass stirrer or the stirrer shaft with anchor or pitched-blade element through the central
opening of the reactor cover before you place the cover onto the reactor and connect it to the stirrer
motor (see Section 3.3: Installing the Overhead Stirrer).

Note
Before you place the reactor in the thermostat, we recommend that you install the Tr sensor and other inserts in order to check their distance from the stirrer or the bottom of the reactor. We also recommend that you add the reagents and solvent for the starting volume and possibly check the ll level of the rst ll. The Tr sensor must be immersed in the reaction solution to a depth of at least 1.5 cm for glass sensors or 2.5 cm for sensors made of Alloy 22 to give correct measurement values.

3.5.1 Installing the Receptacle for the 500 mL Reactors

– Insert the receptacle into the thermo-
stat with the window heading forward.
Make sure the locking pin on the side
snaps into place.

3.5.2 Openings of the 500 mL Two-Piece Reactor Cover

The openings of the 500 mL two-piece reactor are the same like the openings of the 1000 ml two­piece reactor. (See chapter 3.4.1)
– Remove the assembled reactor from the
reactor holder and insert it into the thermo­stat.
– Attach the drain union (ME 51 162 685) to

3.6 Installing the 250 mL Two-Piece Reactor

Since the reactor itself is smaller than the 1000 mL reactor, you have to use a receptacle
(ME 51 162 698) for tting it into the thermostate (See chapter 3.5.1). In addition you need to use the smaller reactor stand for the 250 mL reactor (ME 51 162 758):
– Push the glass stirrer or the stirrer shaft with anchor or pitched-blade element through the central
opening of the reactor cover before you place the cover onto the reactor and connect it to the stirrer
motor (see Section 3.3: Installing the Overhead Stirrer).
– Place the reactor in the reactor stand.

Design and Operating Principles

4 Design and Operating Principles

The OptiMaxTM 1001 comprises four modules:
• Electronic control unit
• Thermostat
• Measurement system
• Touchscreen
The Touchscreen is used to control the OptiMax™ 1001, to perform experiments and manage the related data (store and export experimental data). See document number

METTLER TOLEDO OptiMax™ 1001 39
Safety System

7 Safety System of the OptiMax™ 1001

The safety system monitors safety with chemical reactions as well as the safe operation of the instru­ment functions.
Safety with chemical reactions
The safety with chemical reactions is assured by monitoring the limit values of the temperatures.
You as the user bear full responsibility for selection of the safe limit values and the reaction control. In the case of chemical reactions with a virtually unknown prole, you are responsible for prevent­ing the reactor reaching a hazardous condition long before the limit values of the intrinsic safety are reached and before the safety system would respond.
Intrinsic safety
The operation of the instrument is monitored.
For every instrument conguration used, you are responsible for ensuring that the entire system is safe if a power failure occurs and that the reaction currently in progress cannot get out of control.

7.1 Measures for Chemical Safety

• Monitoring the limit values for Tr, Tj and Tc dened by you; triggering emergency programs if limit
values are exceeded.
• Limitation of the Tj set value to Tj end in the distillation or reux mode.
• The safety temperature Tsafe you dened is used as the set temperature for emergency program
E (see also Section 8.4.3).

7.2 Measures for Intrinsic Safety

The following measures have been implemented for error recognition and for effective intervention when error conditions arise:
Electronics
• Monitoring the microprocessor for breakdown (watchdog).
• Monitoring of the stirrer motor
• 100-Ω resistor as reference for checking the A/D converter (Temp. sensors).
Software
• Self-test of the microprocessor system after switching on.
• Restriction of the temperature difference "Tj - Tr" to maximum 60 K in the Tr and distillation modes
to avoid glass breakage.
• Monitoring all measured values for plausibility and failure.
• Monitoring of the safety limit values.
• Plausibility test of parameters.
• Error recognition and triggering of emergency programs.
40 METTLER TOLEDO OptiMax™ 1001
Safety System

7.3 Temperature Monitoring

To ensure the acquisition of reliable values of the measured temperature, the electronics employs
a reference value in the form of a precision resistor that corresponds to the resistance of a Pt100 at 266 °C (= 200 Ω).
Tj sensor
The Tj sensor is monitored for a preset measured value range. If values fall outside this range, emer­gency program E is triggered.
Emergency program A is triggered if the sensor is defective.
Tr sensor
The Tr sensor is monitored for a preset measured value range. If values fall outside this range, emer­gency program E is triggered.
This program is also triggered if the sensor is detached or defective.
Tc sensor
The Tc sensor is monitored for a preset measured value range. If values fall outside this range, emer­gency program A is triggered.
The electronic system is designed so that if a short circuit or failure occurs, -125 °C is displayed.

7.4 Emergency Programs of the OptiMax™ 1001

The microprocessor of the instrument can trigger two emergency programs, emergency program A
or E.
• As long as emergency program A is active, errors which trigger this program cannot be reset, i.e.
you have to switch off the instrument and rectify the error. An exception is the emergency program "Tc higher than Tc max".
• Errors which trigger emergency program E can be reset, i.e. you can continue the experiment when you have rectied the error.

7.4.1 Emergency Program A

If this emergency program is triggered, the following message is displayed: "Heater and Peltier ele­ment switched off!" followed by the error cause.

Maintenance and Servicing

8 Maintenance and Servicing of the OptiMax 1001

Any maintenance or servicing not specically described in the following must be performed by METTLER TOLEDO service.
Any maintenance or service work not performed in strict accordance with the directions given in previous sections and especially the directions mentioned in the following shall ab­solve Mettler-Toledo AG from any liability whatsoever in regard to the consequences of such improper work!
We strongly recommend you to have the instrument inspected once a year by a METTLER TOLEDO
service engineer.
8.1 Checking the Reactor
To check the reactor vessel for possible damage (scratches and cracks), it must be empty, clean, dry and open. Small hairline cracks can be detected by refraction using an additional light source (focused, not dispersed light).
8.2 Replacing Valve Plug and Sealing Ring of the Bottom Drain Valve
The 2-piece reactors are supplied with a bottom valve with a plug made of LUBRIFLON 9041). If the plug becomes black and hard through excessively high temperatures, or has been attacked by chemicals (swollen), you can replace just the plug. We also recommend to replace the sealing ring from time to time.
Pressure screw
Valve plug
– Loosen the spindle of the drain valve, unscrew the pres-
sure screw and pull the valve out of the valve guide.
– Using a sharp knife, make two or three vertical cuts in
the plug, turn it slightly and pull it away from the glass spindle.
– Warm the new plug in hot water and push it over the
glass spindle. A groove in the glass spindle helps to keep the plug in place.
Spindle Sealing ring
1)
Valve plugs made of different materials are available
• "LUBRIFLON 904" (light blue color) is a PTFE material with a ller. It can withstand high pressures,
remains stable and has a good exibility, and exhibits a low coefcient of thermal expansion.
• "LUBRIFLON pure" (white color) is the same PTFE material but without the ller; it cannot there-
fore withstand such high pressures.

8.3 Changing the Coolant

If you change the coolant, you must rinse and dry the tubing in the instrument before you use the new coolant.
– Remove the connection tube rst at the "Cooling In" inlet, and then at the "Cooling Out" outlet.
– Rinse and dry the tubing in the reverse direction (from the "Cooling Out" outlet).
METTLER TOLEDO OptiMax™ 1001 43
Maintenance and Servicing
– Afterward ll the tubing with the new coolant.

8.4 Cleaning the Interior of the Thermostat

If chemicals get into the thermostat,
– switch off the instrument and disconnect it from the power supply.
– In case the thermostat was previously heated up, wait until it cooled down to room temperature.
– Remove the reactor and if necessary the receptacle and clean the interior of the thermostat with a
solvent suitable for removing the substance.
The material of the thermostat is anodized aluminum. Do not use any strong base for cleaning!
Caution

8.5 Cleaning the Instrument

The housing of the instrument is not watertight (i.e. splash proof). We therefore recommend that you clean the box with a cloth soaked in ethanol.
– Do not clean the cover plate of the reactor box until it has reached room tem-
perature!
Risk of burns
– In case you have any doubts regarding the compatibility of certain cleaning or
decontaminating agents with parts of the instrument or substances contained therein, contact a representative of METTLER TOLEDO or your local service
engineer.

10.4 Cooling

The OptiMax™ requires a constant ow of coolant liquid. Either tap water or a cryostat may be used.
If the water is polluted or has a high degree of hardness, lters should be installed in the inlet line.
• Temperature range of the cooling liquid - 40 °C to 60 °C (inlet temperature)
• Min. ow rate 2 L/min (at 15 °C)

Technical Data
• Coolant connections in/out with hose nipple for tubing with 8 mm inner
diameter (included in delivery)
If you want to use a cryostat for cooling, we recommend the WKL 2200 from LAUDA. This instrument has been tested for the use in combination with the OptiMax
™
.
NOTE: Operation without coolant ow triggers an emergency program (temperature of the coolant outlet Tc > 60 °C).
