Brandtech* RC5 Chemistry-HYBRID Vacuum Pump

Combines rotary vane and diaphragm technologies to support freeze-drying, molecular distillation, and other applications in the fine vacuum range. Ideal for freeze-dryers up to 6 L in capacity and applications requiring vacuum down to 3 x 10-4 torr.
This two-stage rotary vane vacuum pump is backed by a two-stage diaphragm pump. The diaphragm backing pump minimizes interactions between solvent vapors and pump oil, reducing service costs and pump downtime. Always use a cold trap with applications involving solvent vapors.

Supplied with an integrated gas ballast and oil mist filter, pump oil, operating manual and one-year manufacturer's warranty. For 120V, 60Hz. Other voltages available.
