| Use: | Pneumatic depth-specific samplers (commonly called syringes) are used to collect ground water samples at discrete intervals. |
Description:
A variety of samplers are available in which the sample container is pressurized or evacuated. When the container is opened or pressure released, the sample enters the collection instrument.
