Heidolph Rotavac Valve Tec Diaphragm Vacuum Pump

The Heidolph Rotavac Valve Tec Diaphragm Vacuum Pump is a reliable and efficient solution for handling solvents with low to medium boiling points in laboratory settings. Designed with durability and longevity in mind, this vacuum pump features components made from chemically resistant fluoropolymer, ensuring excellent resistance to corrosive substances. The PTFE diaphragm design guarantees a superior lifespan, while the metal core in the head cover and clamping disc ensures long-term performance stability.

The direct pump drive, free from belts, operates quietly and minimizes vibrations, creating a conducive work environment. Additionally, a physically optimized gas ballast valve prevents condensate buildup within the pump. With a maximum pumping speed of 0.53 CFM (0.9 m³/h), ultimate vacuum levels of 12 mbar (9 Torr) without gas ballast and 20 mbar (15 Torr) with gas ballast, and the capacity for two heads and two stages, this vacuum pump offers reliable performance for a variety of applications. Its compatibility with Hei-VAP Expert Control/Ultimate Control rotary evaporators makes it a valuable addition to any laboratory setup.

All of our equipment is in excellent condition and will be fully tested to perform at factory specifications before being shipped.
