CO2 Metering Pump

Peristaltic pump is used to move the desired gas by virtue of volume instead of by pressure. Requires either a two stage regulator on the gas bottle of choice or a demand style regulator. This pump provides a very precise control method of gas delivery to the chamber or flask. Four roller pumping head with 1/16” ID tubing. Flow rates ranging from 0.004 mL/min to 75.19 mL/min. 7 ¾” x 5 ¼” footprint. Easy to use keypad interface, with audible alarm.
