KNF Neuberger - LABOPORT* Single Stage Oil-Free Vacuume Pumps, KNF Neuberger

These oil-free vacuum pumps feature fluoropolymer resin heads and Kalrez* resin valves for handling aggressive corrosives without the risk of damaging the pump. The pumps can be used with gel drying, vacuum concentration, vacuum ovens, and rotary evaporation equipment. The Kalrez resin multi-port valves tolerate ingestion of occasional liquids without damage or degradation of vacuum performance. The fluoropolymer resin heads do not peel or corrode when exposed to most solvents. Single-stage pumps are ideal for moderate vacuum applications. Two-stage 10L/min. pumps are ideal for small vacuum jobs that require a low flow rate. Two-stage 20L/min. pumps are ideal for the distillation of low (35 to 60°C) and medium (60 to 80°C) BP solvents. Pumps KNF10008 and 14224-134 are useful for the distillation of medium (60 to 80°C) and high (80 to 110°C) BP solvents. Deep vacuum pumps 26678-020 and 14224-136 are designed for reflux reactions and for distilling difficult-to-evaporate solvents such as water and high (>110°C) BP solvents. Parallel head pumps 26678-024 and 14224-138 are ideal for high flow vacuum for large scale distillation of low BP solvents (35 to 60°C). The 400mL dry ice trap (26678-056) has a glass body and a Plexiglas* lid. It is recommended as a pre-trap to collect liquids and reduce processing time when used with pumps in rotary evaporation, gel drying, vacuum concentration, and vacuum ovens. For maximum efficiency, the dry ice trap should be placed before the pump.
