Bailers for straight-forward collection and visual examination of water samples in different environments. Available in PVC, Polyurethane (weighted), and biodegradable models, and in 0.7 x 36 in. and 1.5 x 36 in. sizes. 24 units per case. Samples are collected by gently lowering the bailer into the water column and allowing water to fill from the base upwards through a non-return ball valve. As the sample is retrieved the ball will sink to the bottom of the bailer to close and trap the water. Sample release devices are provided to ease collection of samples without spillage.
- Routine sampling from boreholes
