Diaphragm Pumps

These Cole-Parmer vacuum pumps offer extremely quiet operation and are capable of reaching an ultimate vacuum of <2 mbar. Pumps allow for faster processes by increasing the evaporation rates by 30%. Model 72226-53 is ideal for evaporator applications where cost is a necessity. Model 72226-55 offers the efficient 24-volt electronically speed-controllable motor which can accommodate a wide range of input voltages, from 90 to 260 VAC. The speed regulation allows for pin-point accuracy for those situations where an analytical pure vacuum is needed.
