• 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 F-1xx.

replace them when they are brittle.

diameter (approximately 5 mm).

• 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.
