Cole-Parmer Tubing PumpMasterflex C/L Tubing Pumps from Cole-Parmer now feature a redesigned head with mechanical and ergonomic improvements. The new head is designed to provide 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 tubing pumps are encased in a stackable, compact ¼-DIN housing for mounting in an equipment rack or for placement on a lab bench. The tubing pump’s head construction is of chemical-resistant engineered plastics and stainless steel. In addition, these tubing 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. The peristaltic tubing pumps accept microbore/autoanalysis tubing in continuous lengths for fast loading with no occlusion or tension adjustment. – ColeParmer.com/19560
