Pumps Vacuum Pumps
Complete oil-free vacuum system for rotary evaporators, concentrators, and other laboratory vacuum applications generating harsh chemical fumes
System is ideal for rapid solvent stripping. Precise control of boiling enables smooth solvent removal. Gauge/control regulator enables fine adjustment of vacuum level. Handy switch provides instant end to bumping/foaming condition.
Inlet and outlet glass separators capture condensates, protecting the pump and laboratory atmosphere. Automatic self-cleaning feature purges diaphragms with air at conclusion of each evaporation, ensuring run-to-run consistency, maximum pumping efficiency, and long diaphragm life.
Two torr model (Models 2026 or 2027) for evaporating solvents with atmospheric pressure boiling points up to 160°C (includes DMF).
Nine torr model (Model 2025) for evaporating solvents with atmospheric pressure boiling points up to 100°C.
Systems have chemical resistant fume contact surfaces, durable 2 head dry PTFE diaphragm pumps, easy to operate controls.
