The new Masterflex® L/S® portable sampling pump, developed by Cole-Parmer, features the latest Easy-Load® pump head for faster tubing changes and flow stability. The variable-speed drive has a maximum speed of 400 rpm, enabling flow rate adjustment based on application.
The self-contained 12 VDC rechargeable battery provides a 4-hour running life, or indefinitely from any AC or 12 VDC power supply. Users can charge the internal battery from an AC power supply or a DC voltage source of lower voltaic potential than the battery itself. Ideal for remote pumping typical of environmental or agriculture applications.
