Vacuum / gas circuit

Vacuum pump (recommended type:

Vacuum Pump V-710)

For most applications a vaccum is used to signiﬁcantly reduce

the boiling point of the liquid content inside the evaporating ﬂask.

2 + 3

Aeration / inert gas inlet at the

optional vacuum controller and the

aeration valve

The aeration valves at the optional vacuum controller and the

aeration valve of the Rotavapor are used to aerate the Rotavapor.

Under inert conditions, both aeration inlets must be connected

to an inert gas source with regulated output pressure equal to

ambient air pressure!

Vacuum sensor tube at vacuum

controller

If a Vacuum Controller V-850 / V-855 is installed, a tube connec-

tion must be established to detect the vacuum level inside the

glassware.

Cooling medium circuit

Chiller or cooling water tap (optional

with cooling water valve)

When a chiller is used, up to 300 liters of mains water can be

saved a day during operation. In addition, higher process safety

and lower solvent emissions due to the constant, low cooling

temperature can be achieved.

The cooling water valve can also signiﬁcantly reduce cooling

water consumption by cutting off the water supply when no

cooling is necessary.

Replenishment water tap For safety reasons the replenishment water tap must not be

connected when a heating medium different to water is used!

Water ﬂow sensor Detects cooling water ﬂow when installed.

Flow reducing valve The valve can be used to reduce the cooling water ﬂow to

achieve the best cooling to water consumption ratio.

Condensate cooler This cooler inhibits evaporation from the receiving ﬂask. It is part

of some glassware conﬁgurations.

Cooler(s) Depending on the type of glassware conﬁguration, one or more

coolers can be connected in serial.

Cooling water output to sink / return

loop to chiller

The warmed cooling water can be disposed of into a sink or

reused in a closed cooling cycle when a chiller is used.
