Edwards RV8 Two Stage Rotary Vane Pump; 115 to 230 V, 50/60 Hz, 1 Phase (Factory Set to 230 V for Europe), Cole-Parmer (CAT#: STEM-DS-0597-LC)

The Two Stage Rotary Vane Pump is manufactured by Cole-Parmer. These pumps are designed for industrial applications, chemical applications, mass spectrometry, sample preparation, electron microscopy,high-energy physics and R&D. The unique mode selector enable performing high-throughput and high-vacuum task with only one model. These pumps feature a two-position gas ballast. The pump acts quickly and can handle large amounts of vapor.
