6.1.4 Fitting the receiving flask
Materials required:
Grease Glisseal 40 blue (order number 048197)
u Apply a thin coat of Grease Glisseal 40 blue to the glass stopcock (1).
u Fit the receiving flask (3) onto the condenser from below and secure it with the ball
joint clamp (2).
6.1.5 Vertical adjustment
The rotary drive unit together with the glass components can be raised or lowered in
the following ways:
Using the handle (1), the evaporating flask can be lowered into and lifted out of the
heating bath (see Chapter6.2.1 "Raising and lowering the evaporating flask",
page33). To prevent the evaporating flask and the vapor duct from colliding with
the heating bath, a lower stop can be set using the screw-handle (2).
If an especially large evaporating flask or a long vapour duct is being used, the
screw (3) can be loosened with the aid of the TX30 Torx key supplied and the en-
tire vertical adjustment range moved up or down (see Chapter "Moving the vertical
adjustment range up/down", page30).
Moving the vertical adjustment range up/down
CAUTION
Risk of injury when adjusting apparatus height
u Make sure that your fingers are not trapped when adjusting the apparatus height,
especially when using the safety guard.
u Make sure that all tubing is long enough and is not under strain after making the
adjustment.
