Solinst Model 407

The Solinst Bladder Pump features a new design providing consistent, high-quality samples in all types of applications. It offers excellent performance and reliability. With Solinst Bladder Pumps, there is the assurance that there is no air/water contact during 
sampling. It meets the most rigorous US EPA standards for VOC 
groundwater monitoring.
The bladder guarantees that drive air or gas does not contact the sample, thus avoiding degassing or contamination. Solinst Bladder Pumps are rugged and long-lasting.  Santoprene® bladders are ideal for dedication, however, the new easy-to-replace bladder cartridges are excellent for those who prefer to change bladders after each use. The bladder and intake filters are simply replaced in the field in just a few minutes—no special tools are required.
Excellent for either regular flow or low flow sampling, the stainless steel pumps can lift from depths up to 150 m (500 ft) below grade. The new PVC Bladder Pump operates up to 100 ft (30 m) below grade.
