The portable Micropurge Sample Pro Pump is designed to meet the needs of customers who require portable low-flow sampling. The Sample Pro pump operates by pressing compressed air on the outside of the bladder which in turn pumps the liquid up the inside of the bladder ensuring that there is no contact between the sample and compressed air. The Sample Pro pump is ideal for consultants in the field as it contains fewer parts and disassembles without tools. These features enable easy decontamination and quick-change bladders. Its push-in connections provide greater ease of use in applications in which the tubing will be frequently changed. In contrast to many pumps used in the low flow industry, a connection eye is provided on top of the push-in assembly for when a support cable is used.
