3.3.4 Libraries
Fig.10: "Libraries" selected on main menu
The menu item "Libraries" on the main menu of the Interface I-300 offers access
to two libraries:
Solvent library
Wearing parts
Solvent library
The Interface I-300 has an internal solvent library. That library lists the most common
solvents (e.g. ethanol) in alphabetical order. For each solvent, the library contains an
algorithm that calculates the optimum vacuum setting from the actual figures for
heating bath temperature and coolant temperature. The specified vacuum setting is a
dynamic figure that alters automatically according to the current temperatures of
coolant and heating bath until they too have reached their specified settings.
Fig.11: Entries in the solvent library
NOTE
The individual solvents can be saved as favorites. A distillation process can be
started directly from the solvent library.
NOTE
When the heating bath and the recirculating chiller are connected, the actual figures
are automatically applied. If equipment of a different make is connected, the set
temperatures on the devices concerned have to be entered as specified settings on
the interface.
Wearing parts
The Interface I-300 offers a list containing a selection of the wearing parts for the
BUCHI Rotavapor system. The list is divided into two columns. The left-hand column
itemizes the wearing parts in alphabetical order. The right-hand column shows the
order numbers for the wearing parts.

u Connect two tubes between the AutoDest sensor (2) and the cooling condenser
(4). When doing so pay attention to the direction of flow of the coolant. The arrows
on the AutoDest sensor indicate the direction of flow.
NOTE
The distance between the AutoDest sensor and the cooling condenser should not be
more than
10 to 20 cm so as not to falsify the readings for the incoming and outgoing coolant
temperatures in the distillation system.
u Connect a tube between the coolant inlet (5) on the AutoDest sensor and the
outlet of the recirculating chiller.
u Connect a tube between the coolant outlet (6) on the AutoDest sensor and either
the inlet of the recirculating chiller or another cooling condenser.
u Insert a vapor temperature sensor (1) in the cooling condenser and fix it in place.
u Connect the outgoing cable (3) from the AutoDest sensor to the VacuBox. Use the
connection marked "VT/AS" for this lead.
NOTE
The coolant must not contain any air bubbles as otherwise proper functioning of the
AutoDest sensor is not guaranteed.
NOTE
Installing automatic mode sensor on R-220 Pro:
The installation of the automatic mode sensor on the Rotavapor R-220 Pro is described in the operating instructions of the Rotavapor R-220 Pro.
BÜCHI Labortechnik AG Installation | 5
Operation Manual Interface I-300 39/96
5.4 Connecting foam sensor (optional accessory)
The foam sensor uses infra-red to measure the level of foam formation inside the
evaporating flask and initiates one or more short venting bursts to combat the foam.
When de-foaming is active, it is indicated by the symbol on the status bar of the
Interface I-300/I-300 Pro.
The foam sensor passes through the cooling condenser of the R-300 into the
evaporating flask. The communication cable from the foam sensor is connected to the
VacuBox, see Chapter3.2.3 "VacuBox (connections)", page12.
IMPORTANT
Risk of heat damage to electronic components
u Only use the foam sensor at vapor temperatures up to 85 °C.

u Feed the foam sensor together with holder through the cooling condenser and the
vapor duct into the evaporating flask of the Rotavapor R-300 and fix in place with
the clamp nut. When inserting the foam sensor, make sure that the sensor rod
5 | Installation BÜCHI Labortechnik AG
40/96 Operation Manual Interface I-300
passes centrally through the components.
The tip of the foam sensor should be positioned approx. 4 to 5 cm below the
ground neck of the evaporating flask.
u Connect the communication cable from the foam sensor to the VacuBox. Plug the
connector into the socket marked "FS". For details, see Chapter3.2.3 "VacuBox
(connections)", page12.
NOTE
If the immersion angle of the Rotavapor is to be more than 30°, the small washer
supplied must be fitted on the foam sensor in order to prevent the condensate
running back into the evaporating flask. The washer is slid over the glass tube of the
foam sensor so that it comes to rest in the area below the drip catcher of the cooling
condenser. The tip of the washer should point downwards.
5.5 Connecting valve unit for external vacuum
The Interface I-300 can be used together with the VacuBox to control an external
vacuum. That requires the use of a vacuum valve and a mains power supply adaptor.
For precise control of the vacuum, the use of a Woulff bottle is also recommended.
The interface unit and the VacuBox can be mounted on a laboratory stand, see
Chapter5.1.3 "Mounting interface unit on laboratory stand (optional accessory)",
page31.
u Connect the vacuum valve to the VacuBox using the connection marked VALVE.
u Connect vacuum tubing between the laboratory apparatus to be evacuated, the
VacuBox and the external vacuum unit.
u If a Rotavapor is not connected, connect the VacuBox to the external power
supply by means of the mains adaptor.
NOTE
To adjust the regulation accuracy, the hysteresis can be altered on the interface unit,
see Chapter6.5 "Setting hysteresis", page65.
5.6 Operating I-300 and I-300 Pro in parallel
If the Rotavapor is to be controlled from outside a fume hood, there is the option of
connecting two separate interface units in parallel. In that case, distillation can be
controlled from either interface unit. The readings displayed are continuously
synchronized. The servicing functions (e.g. leak test) are controlled by the interface
unit that is currently being used.
If a mobile connection (see Chapter7 "Mobile connection", page67) is desired when
the I-300 and I-300 Pro are operating in parallel, the LAN cable must only be
connected to one of the interface units, preferably the I-300 Pro.
u Connect the remote interface unit to the interface unit on the Rotavapor using the
standard BUCHI communication port (COM). Use a standard BUCHI
communication cable to do so.

6.2.6 Performing automatic distillation
Automatic distillation requires the use of an AutoDest sensor. The AutoDest sensor is
connected to the VacuBox (see Chapter5.3 "Connecting AutoDest sensor to vapor
temperature sensor (optional accessory)", page37) and measures the inlet and outlet
temperature of the coolant and the vapor temperature at the cooling condenser.From
those three readings, the system calculates the parameter settings required for
optimum distillation. During automatic distillation, the temperatures of the heating
bath, coolant and vapor are constantly measured and the specified setting for the
pressure adjusted accordingly.

6.3 Using the solvent library
The Interface I-300 has an internal solvent library. Stored in that library are the most
common solvents together with an algorithm in each case. Based on the chemical
properties of the solvent, the algorithm calculates and dynamically sets the ideal
vacuum according to the current readings for heating bath and coolant temperature.
That means that the distillation process can be started immediately even if the ideal
heating bath and coolant temperatures have not yet been reached.
A distillation process can be started directly from the solvent library.

The Interface I-300 offers an "eco mode" option for saving energy if the distillation
system remains inactive for a predefined period of time. In eco mode, the distillation
system shuts down the activity of the heating bath and recirculating chiller after a
defined delay period so that:
The heating bath does not reheat until the heating bath temperature has dropped
to a defined minimum temperature.
The recirculating chiller does not re-chill until the coolant temperature has risen to
a defined maximum temperature.

6.5 Setting hysteresis
The hysteresis setting is only relevant if the distillation system is not being operated
with a BUCHI Vacuum Pump V-300 but with a different make of pump or with a
laboratory vacuum supply, and is controlled by means of a valve.
The hysteresis setting ensures precise pressure regulation by the valve or the valve
unit. The hysteresis is the maximum allowed deviation of the vacuum from the
specified setting before the system corrects the pressure. The pump is switched off/
valve is closed when the vacuum has reached the lowest possible pressure. If the
pressure rises and the set hysteresis is exceeded, the pump is switched on again/the
valve opened again.

8.6.1 Offset calibration
An offset has to be specified if the pressure indicated on the interface unit differs from
the pressure indicated by an external reference pressure gauge. The difference
between the two figures is referred to as the offset. The offset applies to the entire
pressure range.
Navigation path
➜ Configuration ➜ Servicing ➜ Pressure offset
u Connect the reference pressure gauge to the same vacuum system that the pump
and interface unit are connected to.
u Navigate to the "Service" screen and select the menu item "Pressure offset", see

Fig.73: Menu item "Pressure offset"
u Enter the pressure measured by the reference sensor.
5 The measured readings will then automatically be adjusted by the specified offset.
8.6.2 Simple calibration
This calibration method is used to adjust the linearity of the pressure sensor at
specific predefined pressure levels. During the calibration sequence the pressure
sensor is calibrated at room temperature in six stages at normal atmospheric
pressure and at 800, 600, 400, 200 and 10mbar.
During the calibration sequence, the system carries out a plausibility check on the
measured readings and indicates a fault if the confirmed readings are implausible.
