Dry vacuum pump technology with built-in advanced vapour management means precise control capability for the distillation of organic solvents and applications handling aggressive vapours and gases.
Welch has improved dry vacuum pump technology with its Dryfast and Dryfast Ultra with built-in advanced vapour management (AVM).
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 and Kalrez valves and using fluorinated plastics on all wetted surfaces, these dry vacuum pumps are for chemical duty laboratory needs.
The six models have flows to 70 litre/min and vacuum levels down to 0.27kPa.
No cold traps are needed for operation.
These stand-alone vacuum pumps need little maintenance.
They are suitable for rotary evaporation, concentrators, evaporators, vacuum ovens, filtration, degassing and other chemical applications.
