Welch improves dry vacuum pump technology with the new Dryfast and Dryfast Ultra having built-in advanced vapour management (AVM).
Advanced vapour management (AVM) means precise control capability for the distillation of organic solvents and applications handling aggressive vapours and gases.
Constructed with solid PTFE heads, PTFE diaphragms, Kalrez valves and utilizing fluorinated plastics on all wetted surfaces, these dry vacuum pumps are designed to meet ever-challenging chemical duty laboratory needs.
The six new models feature flows to 70l/min and ultimate vacuum levels down to 2-Torr.
No cold traps are needed to operate.
These stand-alone vacuum pumps need very little maintenance leading to low cost of ownership and improved productivity.
Welch application certifies Dryfast and Dryfast Ultra for rotary evaporation, concentrators, evaporators, vacuum ovens, filtration, degassing, and other chemical applications.
