Collection flask (Fig. 5/
7
) collects on the suction side of the pump
particles and drops that were, contrary to the requirements of the
pump, suctioned from the vacuum chamber. The collection flask is
coated (implosion protection) and fastened to the vacuum pump
system via a flask clip (
5
).
The high-performance condenser (
2
) at the pump outlet once again
recollects solvents from the pumped gas instead of allowing it exit
into the environment or fume hood. The high-performance con-
denser is surrounded by a shell for temperature insulation and
explosion protection.
Solvents deposited in the high-performance condenser are col-
lected in the coated (for explosion protection) collection flask (
6
). A
flask clip (
5
) secures the glass flask to the condenser flange. A
recirculating cooler or continuously flowing cold water (or another
cooling media) cools the high-performance condenser to the
condensation temperature.
5.3.2. Vacuum pump system functions
The flow of the pump can be set via the rotary knob on the control
terminal (
3
).
I If the rotary knob is rotated to the left until it engages the
mechanical indent, the pump will rotate with a minimum flow
rate of 15%.
If the rotary knob is then rotated farther to the left (past the
mechanical indent), the vacuum pump system's pump will be
switched off.
The gas ballast switch (
4
) can be used to open and close the gas
ballast valve on the vacuum pump system's pump (see Chapter
5.6).
