VACUUBRAND RZ 2.5 Rotary Vane Vacuum Pump
Product Description
VACUUBRAND RZ 2.5 Rotary Vane Vacuum Pump
Ultimate Vacuum
0.002 mbar (0.0015 Torr)
Maximum Pumping Speed
1.65 CFM at 60Hz
Number of Stages
2
- High flow rates even at vacuum levels approaching ultimate vacuum
- Very good ultimate vacuum even with gas ballast
- Vacuum-tight at switch-off; external anti-suckback valve not needed
- Large oil volume: Long intervals between oil changes
- Ease of maintenance due to telescopic design
The one-stage RE 2.5 and two-stage RZ 2.5 are high-performance rotary vane pumps with extra compact design and low weight. They are the ideal solution for a wide range of laboratory and process applications that require a low ultimate vacuum at medium gas flow rate. Typical applications are lyophilization, fine vacuum distillation and evacuation of small volumes, e.g., for utilization of µ-focus x-ray tubes or filling with pure gases.
