Zefon ZBP-308 Air-O-Cell Bio-Pump Bubble Tube with NIST Certificate

The Zefon Bio-Pump® Bubble Tube is used as a primary standard in calibrating the Bio-Pump®. Attach the bubble tube to the pump as shown (tubing provided with bubble tube). Then run the pump in calibration mode while inserting the end of the tube in soapy water so that bubbles travel up the tube. Timing the bubbles between the indicator line will indicate your flow rate.
