Gel Dryer

Vacuum gel dryers are commonly used to dry sequencing gels due to their large surface area. To dry sequencing gels crack-free requires steady vacuum as provided by two stage pumps (8 mbar / 12 mbar). Harsh chemicals are evolved from vacuum gel dryers so a chemical duty diaphragm vacuum pump is necessary with flow rate of 35 lpm. A liquid trap or catch pot in-line is necessary to collect condensate that forms as hot vapors come off the gel dryer and condense in-line. These condense vapors need to be collected in the liquid trap so they are not ingested into the diaphragm vacuum pump. A 2 liter filtering flask can be used as a liquid trap. 

Vacuum gel dryers and concentrators are sometimes found together in life science laboratories. Laboratories that are short of space find it convenient to use one vacuum pump for both devices. One chemical duty diaphragm vacuum pump can be used to serve the two devices by assembling a basic manifold with tubing and two in-line valves. A concentrator needs a deeper vacuum to evaporate solvents compared to a gel dryer. Contact our application specialists to select the chemical duty diaphragm vacuum pump that will work with your particular concentrator application.
