Envco – Environmental Equipment

The models 1940 & 1942, are designed for high pressure operating conditions in deep bore holes to a depth of 300 ft. (100 meters) These samplers are typically used in applications deeper than 50 ft (15 meters) depth. However, the installation depth can be increased indefinitely, when the collected samples are staged in up to 300 ft (100 meters) lifts using the 1940 Sampling Stage. Both the 1940 and 1942 samplers provide excellent performance for pore liquid sampling with parts per million sensitivity from vadose zone investigations. The cup-end plug assembly provides a threaded seat for the stainless steel check valve, and a stepped shoulder to epoxy bond the high temperature ceramic (B02M2) cup.

The 1942 is a slimmer version of the 1940 having a 1.312 " (3.3 cm) OD compared to the 1940's 1.9" (4.83 cm) OD and both having the same body length (30"-77cm). Hi pressure/vacuum soil water sampler. Slim Tube functions exactly like our 1940 Soil Water Sampler only slimmer in design. Slim Tube pressure/vacuum soil water sampler used for deep sampling down to 300 foot (100m) depths, or where long lateral runs are required. The sampler consists of a 2 bar (200 kPa) ceramic cup, PVC body, and an end cap. High-pressure compression fittings allow connection of polyethylene vacuum and pressure tubing.
