Solinst Bladder Pumps have low flow capability and ensure that no drive gas comes into contact with sample water, which makes them ideal for VOC sampling. Using a Model 464 Pump Control Unit, along with a Solinst 12V Compressor, allows very slow compression of the bladder. This causes less disturbance to the sample water, providing higher quality samples.
