High quality bladder pumps enable reliable and accurate sampling

Solinst’s bladder pumps provide consistent, reliable samples in all types of applications. Ensuring no air/water contact during operation, they are ideal for sampling for VOCs. They are excellent for regular flow or low flow sampling, with rates from 2 L/min (0.5 gpm) to 100 ml/min (0.03 gpm) or less, using a Solinst Model 464 Electronic Pump Control Unit.

Bladder pumps are stainless steel in 1.66" and 1" diameters. They are effective at any angle, to depths of 150 m (500 ft) below grade. Standard PFAS-free PTFE bladders are durable and ideal for dedication; inexpensive polyethylene bladders are also available for short-term applications, and to help avoid cross-contamination.
