Description
Bladder Pump 407 provides consistent, high-quality samples in all applications.
The Solinst 407 Bladder Pump allows for consistent, high-quality samples in all types of applications. It provides excellent performance and reliability. With Solinst bladder pumps, there is assurance that there is no contact between air and water during sampling. It meets the strictest US EPA standards for VOC groundwater monitoring.
The bladder ensures that no propellant air or gas comes into contact with the sample, avoiding outgassing or contamination of the sample. Solinst bladder pumps are robust and durable. PTFE bladders are ideal for dedicated applications, while less expensive polyethylene bladders are available for those who prefer to change bladders after each use. Bladders and inlet filters are easily replaced in the field in minutes. No special tools required.
Excellent for either regular or low-level sampling, stainless steel pumps can lift from depths up to 150 m (500 ft) below grade.
Low Flow Purification and Sampling
Low flow sampling provides excellent quality samples by reducing turbulence. It also reduces purge volumes and thus sampling time and disposal costs. When using a Solinst Model 464 electronic pump controller, the Solinst bladder pump can be adjusted to provide continuous output of 100 ml/min. or less.
Using a flow cell system during low-flow sampling allows for continuous analysis of clean water, in-line, as it flows, so sampling can begin as soon as readings stabilize.
Packers are also available to further reduce purge volumes and for faster sampling times.
