Vacuum Source and Setup
The most effective vacuum source is obtained by using a mechanical pump with a
minimum free air displacement of 50 liters/minute developing a minimum vacuum of
25 in. Hg. Since inadequate vacuum can cause problems such as gel cracking, the use of
house vacuum or a water aspirator is not recommended. The vacuum pump must be
protected by a cold trap and should also be protected by a vapor trap when corrosive
solvents such as acetic acid or methanol are being evaporated. See Accessories on page
22
Plug the vacuum pump into the electrical receptacle on the right side of the Gel Dryer and
connect the vacuum line to the vacuum port at the rear of the Gel Dryer.
