Clear eco bailers for Sampling Groundwater

We manufacture a large variety of Clear PVC eco Bailers for your groundwater sampling needs. 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.

PVC – PRO: We have innovated a new class of wide mouth bailer in 1.5 inch diameter.

PVC and PVC – PRO eco Bailers are clear and are available in Regular and Weighted formats.

All bailers are PFAS, PFOS & PFOA free.

Bottom Emptying

The 0.46 inch (12 mm), 0.7 inch (18 mm), and 1.5 inch (38 mm) bailers come with the handy  Emptying Device which can also be used to direct the discharge flow and also for collecting VOC samples.

Groundwater Filtration

Clear PVC eco Bailers are easily fitted to Waterra 0.45 micron Groundwater Filters if your program specifies collection of samples for metals analysis.

Low Density Polyethylene (LDPE) tubing (1/4inch OD or 1/2 inch OD)  fits into the Bottom Emptying Device and connect with a Waterra Groundwater Filter. Bailed samples can be gravity flowed directly through the filter and captured in a sample container.  It usually takes less than 2 minutes (depending on turbidty)  to filter a sample this way.

Some things to think about!

  • Most popular: Clear PVC 1.5 inch x 3 feet long 1 litre eco Bailers in the classic ecoPVC-153 style and the wide mouth ecoPVC-PRO-153 format
  • Use a smooth hand over hand technique to minimize sample agitation when recovering your sample from the well
  • We don’t recommend tipping over the bailer to decant your sample from the top of the bailer as it aerates the sample and is tricky to handle the bailer. That’s where the Emptying Device comes in so handy.
  • ecoBailers fit well with Waterra Groundwater Filters


Clear PVC eco Bailers for sampling groundwater are as heavy (or heavier) than conventional weighted bailers.  They sink straighter and the efficient valve design makes it the fastest sinking bailer available.

  • 4 popular sizes: 0.46, 0.7, 1.5 and 3.3 inch diameters
  • PRO – wide mouth available in 1.3 inch diameter only
  • faster sinking than polyethylene bailers
  • inspect your sample through the clear tube
  • fits with Waterra inline filters
  • no leak PVC ball

Clear virgin PVC has a density of 1.31 grams per cubic centimeter versus polyethylene, which has a specific gravity of 0.96 to 0.98.

Same design as the popular Clear PVC eco Bailers. Weighted 1. 5 inch PVC and PVC-PRO eco Bailers feature a thicker tube wall. They are more robust.  Bent bailers rattle down the well and sink more slowly. 0.7 inch clear PVC bailers are also available in weighted format.
