The Model 429 Point-Source Bailer is ideal for obtaining high quality, representative “grab” samples of groundwater from specific depths. Sampling can be done without purging.
The Point-Source Bailer is stainless steel with PTFE check balls. It comes in 0.5, 1, 1.5, or 2″ (12.7, 24.5, 38.1, or 50.8 mm) diameters, and 2, 3, or 4 ft. (61, 91, or 122 cm) lengths.
It can be used in an open borehole or screened well, providing a simple, cost effective device for aquifer profiling. Because there are check balls at the top and bottom of the bailer, minimum water enters the sampler during retrieval. The 0.5″ (12.7 mm) OD miniature model is made for use in narrow tubes and direct push devices.
The Model 428 BioBailer is a low cost, disposable PVC bailer. It has a rigid design, tapered ends, and a sturdy handle for easy deployment. Its dense construction means there is no need to use weights for deployment. The 1.5″ x 3 ft. (38 mm x 91.5 cm) version has capacity for over 1 litre of sample water ( 1025 mL), the 3/4″ x 3 ft. (19 mm x 91.5 cm) version holds 200 mL.
The clear PVC allows the sample water to be examined before being decanted using the sample release device. The sample release device, all components of the bailer body, and the packaging are all biodegradable when disposed of in a landfill.
