5.8.2 Cooling water tubes
When connecting the white cooling water tubes,
consider the following:
Use tube clips GL-14.
The tubes used must all have the same inner
diameter (approximately 6 mm).
For safety reasons, secure the tubes with
commercial tube pivoting clamps or cable
binders.
To save cooling water, you can use the Distil-
lation Chiller B-741.
Check the tubes from time to time and
replace them when they are brittle.

5.8.3 Vacuum tubes
When connecting the vacuum tubes, proceed
as follows:
Use tube clips GL-14.
The tubes used must all have the same inner
diameter (approximately 5 mm).
Keep vacuum tubes as short as possible.
When you are operating with the new
Buchi Vacuum Controller V-850/855 and
Vacuum Pump V-700/710 connect a Woulff
bottle between the vacuum source and the
Rotavapor.
When you are operating with a pump other
than a V-700/710, connect a valve unit to the
V-850/855 to control the vacuum.
Tubes do not need to be secured.
Check the tubes from time to time and
replace them when they are brittle.
