The RZ6 is part of the VACUUBRAND?XS series of rotary vane vacuum pumps. These pumps have been designed from the ground up for best performance in laboratory applications. The RZ6 is an excellent choice for freeze dryers up to 6 liters, benchtop centrifugal concentrators or other low-temperature evaporations of high boiling point solvents, molecular distillations, schlenk lines and other applications where diaphragm pumps cannot provide sufficient vacuum.
