The VSL is a powerful, variable-speed peristaltic pump, equipped with our rapid-loading L400 pump head, and driven by a maintenance-free, brushless DC motor rated for continuous duty. It accepts six tube bore sizes, providing the flexibility of six distinct flow ranges. With its broad flow range, smooth and accurate flow control, and remote start/stop capability, this unit is an excellent choice for life science and general laboratory applications.
The pump is configurable to utilize 1.6mm (1/16”) or high-performance 2.4mm (3/32”) wall tubing, giving it the ability to perform in a wide range of applications. The unit ships configured for 1.6mm wall and includes a separate roller assembly for an easy conversion to 2.4mm wall. If you are unsure which wall thickness will work best for your application, please see our Tubing Sample Kit which contains multiple bores of both thicknesses for testing.

INCLUDES: Drive unit, L400 pump head, 1.6mm & 2.4mm rollers assemblies and 6-ft. (1.8m) NEMA 5-15P to IEC 320-C13 power cord. Tubing sold separately. For tubing options see Peristaltic Pump Tubing. Typically ships within 5 business days.
Flow rates are for guidance purposes only and are based upon pumping ambient temperature (22°C/72°F) water at zero pressure and zero lift. Rates may increase/decrease based upon numerous factors including: motor variances, tubing characteristics, fluid viscosity, lift height, pressure and number of rollers. Anko reserves the right to make changes at any time without prior notice. The information provided is not intended for a specific application purpose.
