Solinst Model 428 [110072] BioBailer Clear PVC, 1.5" x 3 ft (38 mm x 91.5 cm), Case of 24. The Solinst Model 428 BioBailer is a low cost, biodegradable bailer made of clear PVC that holds more than one liter of sample. The high quality design features a rigid body that will not bend. The top and bottom of the bailer are both tapered, to prevent hangups in the well. The BioBailer uses a denser PVC construction, eliminating the need for weights in most applications. The transparent body allows the sample to be checked visually for water or product. BioBailers have been tested for non-leaching using the SPLP EPA 1312 extraction process followed by analysis using EPA 8260 for volatiles and EPA 8270 for semi-volatiles. This is a long duration test of 18 hours, which greatly exceeds the expected use time of a disposable bailer.
