- The Electric aspirator 75301-00 produces a low vacuum condition using
Bernoulli's principle by pumping water through aspirator head. When using
75301-00 with rotary vacuum evaporator or for Gel dryer or low vacuum oven,
inflow of a little water or solvent into the equipment do not make trouble to the
instrument. And you can use this equipment continuously if you change the
water in the bath.
- The 75301-00 is manufactured as polypropylene that has chemical resistance
against most solvents. For effective usage, a small quantify of water
(100ml/min) has to be continuously supplied by a user through the drain cock at
the bottom part of the bath and drained through the over-flow nozzle. It reveals
liquid circulation of the inner bath and means dilution that helps the instrument
to be used longer.

- Check-valve is designed for preventing water from flowing backward during the
power failure. But this valve can’t protect the equipment permanently. It is for
short protection that saves the time to fix its original troubles that may be
happened.

The above graph shows that vacuuming fluctuation is depending on water
temperature in the bath.
In case of using for inner circulation for a long time, if the water temperature in
the bath might increase by the motor, the vacuuming condition would be limited.
When you use it for a long time, you had better infuse some cooling water to
decrease the water temperature.

① Whenever possible, supply running water regularly in the tank.
☞ Connect the hose for supplying the running water from In/Out cock and
drain from Overflow nozzle.
② If you are using organic solvents, you must supply running water.
After operation, drain the water in the tank. Draining the water will prevent the
unit loss from the organic solvents and vapor.
③ If running water cannot be supplied, change the tank water as often as is
necessary for its frequency of use. In case of using the toxic solvents, you
must change the tank water more frequently.
④ After operation, Rinse the aspirator thoroughly after each use .
Clean and empty the tank in order to avoid any contamination.
Followings are example of organic solvents which need this sort of special care.
