2 Safety
2.1 Intended use
The Interface I-300 is intended for indicating vacuum within an operating range of
0mbar to ambient atmospheric pressure. The measurement and regulation of the
vacuum is performed by means of a VacuBox. The Interface I-300 has been designed
and built as an item of laboratory equipment and can be used in conjunction with the
following devices:
Distillation apparatus, especially rotary evaporators
Vacuum-drying cabinets
Vacuum pumps
Recirculating chiller
2.2 Use other than that intended
Use of any kind other than that described in the section Chapter2.1 "Intended use",
page8 and any application that does not comply with the technical specifications
(see Chapter3.5 "Technical data", page25) constitutes use other than that intended.
In particular, the following applications are not permissible:
Use of the device in areas that require apparatus that is safe to use in potentially
explosive atmospheres.
Use as a calibration device for other equipment.
Operation at pressures above atmospheric
Damage or hazards attributable to use of the product other than as intended are
entirely at the risk of the user alone.
2.3 Staff qualification
Unqualified persons are unable to identify risks and are therefore exposed to greater
dangers.
The device may only be operated by suitably qualified laboratory staff.
These operating instructions are aimed at the following target groups:
Users
Users are persons that meet the following criteria:
They have been instructed in the use of the device.
They are familiar with the contents of these operating instructions and the
applicable safety regulations and apply them.
They are able on the basis of their training or professional experience to assess
the risks associated with the use of the device.
BÜCHI Labortechnik AG Safety | 2
Operation Manual Interface I-300 9/96

safe and hazard-conscious working practices.
Safety-related incidents that occur while using the device should be reported to the
manufacturer (quality@buchi.com).
BUCHI service technicians
Service technicians authorized by BUCHI have attended special training courses and
are authorized by BÜCHI Labortechnik AG to carry out special servicing and repair
measures.
2.4 Residual risks
The device has been developed and manufactured using the latest technological
advances. Nevertheless, risks to persons, property or the environment can arise if the
device is used incorrectly.
Appropriate warnings in this manual serve to alert the user to these residual dangers.
2.4.1 Faults during operation
If a device is damaged, sharp edges, moving parts or exposed electrical wires can
cause injuries.
u Regularly check device for visible damage.
u If faults occur, switch off the device immediately, unplug the power cord and
inform the operator.
u Do not continue to use devices that are damaged.
2.5 Personal protective equipment
Depending on the application, hazards due to heat and/or corrosive chemicals may
arise.
u Always wear appropriate personal protective equipment such as safety goggles,
protective clothing and gloves.
u Make sure that the personal protective equipment meets the requirements of the
safety data sheets for all chemicals used.
2.6 Modifications
Unauthorized modifications may impair safety and lead to accidents.
u Use only genuine BUCHI accessories, spare parts and consumables.

3 Product description
3.1 Description of function
The Interface I-300 is designed for indicating, adjusting and controlling the complete
distillation system. The Interface I-300 settings enable precise specification of the
individual process parameters.For example:
Rotation speed of the evaporating flask
Specified temperature of the heating bath
Specified temperature of the coolant
Specified vacuum pressure
Duration of the distillation process
The pressure is measured and regulated by the associated VacuBox. Measurement
is independent of the solvent used.

NOTE
Connecting VacuBox with R-220 Pro:
If the Interface I-300 Pro and the VacuBox are operated in the Rotavapor R-220 Pro
system, the following points should be noted: The external valves must always be
connected to the Rotavapor R-220 Pro even if there is an alternative connection on
the VacuBox.

3.2.4 LegacyBox (connections)
Connection of a LegacyBox is required whenever legacy BUCHI laboratory equipment is to be controlled via the Interface I-300. The LegacyBox is connected to the
distillation system using a standard BUCHI communication cable and has other
connection options such as an RS-485 communication port. There is also the option
of incorporating pumps of other makes in the Rotavapor system and controlling them
via the interface. In that case, the pump requires a 0 – 10 V input.
The LegacyBox is fixed to a Rotavapor R-300 or a laboratory stand clamp.

NOTE
The external power supply is only necessary if the LegacyBox is not connected to a
Rotavapor or a vacuum pump and is used for other vacuum control applications
instead. Otherwise the vacuum pump or the Rotavapor supplies the LegacyBox with
power.
0 – 10 V communication port
This connection comprises a 0 – 10 V output for connecting pumps of other makes
and electrically isolated relay contacts. There is also a valve control contact.

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.

4.1 Transport
IMPORTANT
Risk of breakage due to incorrect transportation
u Make sure that all parts of the device are safely packed in such a way as to
prevent breakage, ideally in the original box.
u Avoid sharp movements during transit.
u After transportation, check the device for damage.
u Damage that has occurred in transit should be reported to the carrier.
u Keep packing for future transportation.
4.2 Storage
u Make sure that the ambient conditions are complied with (see Chapter3.5
"Technical data", page25).
u Wherever possible, store the device in its original packaging.
u After storage, check the device for damage and replace if necessary.

5 Installation
5.1 Fitting the Interface I-300/I-300 Pro
The Interface I-300/I-300 Pro can be mounted on one of the following BUCHI
laboratory devices:
Rotavapor R-300
Vacuum Pump V-300
Rotavapor R-220 Pro
Alternatively, the Interface I-300/I-300 Pro can be mounted separately on a laboratory
stand, see Chapter5.1.3 "Mounting interface unit on laboratory stand (optional
accessory)", page31.
5.1.1 Mounting interface on Rotavapor R-300
The Interface I-300 can be mounted and connected up on the vertically adjustable
arm of the Rotavapor R-300.
Tools required: Torx keys Tx20 and Tx30
