New Masterflex C/L Pumps from Cole-Parmer now feature a redesigned head with significant mechanical and ergonomic improvements. The new head provides more secure tubing retention and more consistent performance over the full range of tubing sizes and flow. A single motion opens the cover and releases the occlusion bed for quicker and easier tubing changes. Tubing retainers are self adjusting to accommodate tubing of different diameters.

The peristaltic pumps are encased in a stackable, compact ¼-DIN housing for mounting in an equipment rack or for convenient placement on a lab bench. Pump head construction is of chemical-resistant engineered plactics and stainless steel. In addition, these pumps offer the flexibility of remote start/stop via contact closure, reversible flow, and a max-speed button for fast priming. .

Three motor speed ranges deliver a flow range of 0.002 to 43 mL/min depending on tubing size. These pumps accept microbore/autoanalysis tubing in continuous lengths for fast, easy loading with no occlusion or tension adjustment. Masterflex tubing is available in rolls of 50 or 100 feet—cut to length for an uninterrupted flow path with no fittings or connections.
