These bailers are designed with a special valve and valve seat to provide more positive sealing and less clogging when removing the bailer from the well. All bailers come with the handy Bottom Emptying Spout. It assists in collecting non-aerated samples from the valve end of the bailer, which is ideal for VOC sample collection.
All Clear PVC EcoBailers are easily adapted to the Waterra Groundwater Filters for collection of samples for metals analysis directly from the bailer.
A short length of 1/4″ OD or 1/2” OD LDPE tubing along with the Bottom Emptying Spout can be used to easily connect a Waterra Groundwater Filter to the bailer. This allows the bailed sample to flow by gravity directly through the filter and into a sample container. In many cases a 1 litre sample can be filtered in under 2 minutes using this method.
