The Via-Cell sampler requires the sampling pump to be calibrated at a flow rate of 15 liters per minute to ensure proper collection. Ideally, calibration should be checked prior to and after each collection and as a minimum once per day. It is strongly recommended that a primary standard device such as a soap bubble meter/tube or other NIST certifiable device be be used to calibrate the sampling pump. Second- ary calibration devices such as a rotameter may be used if it is calibrated against a primary standard.
Below are examples of typical devices that can be used for calibration:
Please note that some pumps, including the battery powered Zefon Bio-Pump®, will only work with specific calibration devices. Please reference the operation manual for your pump to determine if special calibration devices are needed.
