Groundwater Double Valve Interval Sampling

Description

eco Bailer Groundwater Double Valve Interval Sampling
Clear PVC – 1.5 inch (38mm) OD and in 1, 3 and 4 foot lengths

Double Valve eco Bailers are used to sample a discreet interval in a groundwater monitoring well. The double valve system can isolate the sample from the water column by means of an upper and lower valve system. Lower the bailer to the target interval and then pull up. Once recovered to surface, the clear PVC allows visual evaluation of the sample.

Manufactured in durable, virgin clear PVC so they have the same attractive advantages as the regular Clear PVC eco Bailers. Here are some of the features:

– two valves: a lower and an upper valve work in conjunction to trap an interval of groundwater
– 1.5 inch (38 mm) diameter
– length options of  1 foot (25 cm), 3 foot (76 cm) and 4 foot (102 cm) lengths
– PVC is heavier and hence sinks more quickly than polyethylene bailers
– clear PVC means you can inspect the sample while still in the bailer.
– PFAS, PFOS & PFOA free
