Description
Manostat Cassette Pump 72-895-20-00 Peristaltic Variable Speed Reversible 115V
The Manostat Cassette Pump (catalog number 72-895-20-00) is a benchtop peristaltic pump that moves fluid by compressing a silicone rubber tube with a series of rotating rollers — no fluid contacts the pump mechanism itself, making it well suited for sterile, corrosive, or sensitive liquid transfer. This unit includes the removable cassette assembly and features variable flow rate control, reversible direction, and two speed ranges selectable via the cassette's dual geared rod drive (providing a 3:1 speed ratio).

Applications
Manostat Cassette Pumps are used in laboratory and light industrial settings for precise, low-contamination fluid transfer. Because peristaltic pumps move fluid entirely through tubing compression — the pump mechanism never touches the liquid — they are a standard choice for metering reagents, dispensing buffers, handling corrosive chemicals, and transferring biological fluids where contamination or cross-contamination must be avoided. The Manostat cassette-style design, popular from the 1970s through the 1990s, makes tubing changes fast: the cassette snaps out for cleaning or tubing replacement without tools. These pumps were widely used in pharmaceutical manufacturing, clinical diagnostics, fermentation, water analysis, and general laboratory liquid handling. The reversible direction control adds versatility for filling and emptying vessels or priming lines.
This Manostat Cassette Pump 72-895-20-00 peristaltic pump is being sold AS-IS for parts or repair. The line cord is frayed and needs to be replaced before any attempt at use. The unit has not been tested and no functionality is guaranteed. The cassette assembly is included and appears intact. The control housing shows general wear consistent with lab use, and the bottom label (showing catalog number 72-895-20-00, 115V/1A, serial number 142) is legible. The power cord plug shows aged, worn prongs. Please view our photo set and contact us if you have any questions.
