The Vacuubrand RZ6 vacuum pump with cold trap is a powerful oil-lubricated rotary vane pump designed for applications requiring deep vacuum and high vapor loads.

In combination with a cold trap, the system is optimally protected against solvent vapors and condensates. This makes it ideal for intensive laboratory applications such as lyophilization, vacuum distillation, and Schlenk techniques. ⚙️ Technical specifications
