ReaXus M1 Class

Single Piston Pumps with Excellent Capability at a Low Cost

The compact M1 Class HPLC Pump consists of single-headed, positive displacement piston pumps that deliver high-performance and precision at an affordable price.

Applications include precise chemical metering, dispensing, and specific HPLC separations. Standard fluid path materials are Stainless Steel and PEEK. With 10 mL/min, 40 mL/min, and 100 mL/min versions, reaching pressures up to 2,000 psi, these pumps capture the majority of typical laboratory fluid transfer applications.
