Our
most popular bailers are constructed of high grade PVC material. Tested and
approved, by an established legal environmental testing firm, for leaching,
absorption and overall performance. Results came in with A+ ratings for
areas tested. Tested under Methods 8260 & 8260B.
PVC naturally sinks in water, due to its specific gravity, relative to
water. No weights are required to restrict flow of sample entering and
exiting bailer.
PVC is very rigid - it stays straight,
never bending or distorting under normal care. This is very important for
the smaller diameter bailers, which are carefully extruded for
straightness.
The PVC material is transparent, to assist in
field sampling that may require visual inspection of the sample taken. For
example the operator can actually see the product sampled from ground water
remediation wells and fuel tanks.
The specially designed top allows the sample
to be poured accurately, with little or no splashing. A strong rigid
tethering attachment is designed for secure fastening of bailer rope.
Each part is press fitted and double welded, to assist in the bonding of
tube to top device.
A redesigned ball seat helps to deter
sticking of the check ball, with out sample loss, between ball and device. A
large 16.5mm opening allows for large volumes of product to rapidly fill the
bailer with minimal disturbance to the sample. It also speeds up sampling
and or purge time, thus saving money. Each part is press fitted and welded,
for little or no leaking between tube and bottom device.
The material of construction for the tube
body is virgin medical grade poly vinyl chloride. This is the same medical
grade PVC resin used in the manufacturing of catheters, for treatment of
medical patients. The top and bottom is constructed from ABS and the
check ball is high grade PVC material. Recently the manufacturer ran
the most extensive spike test available, under method 8260B and 8270.
Results on the PVC were equal to polyethylene, in all areas recognized.
Furthermore, the time where the disposable bailer comes in contact with the
sample is not long enough to cause any adverse reaction, thus resulting in
no cross contamination issue. Test results are available upon request. |
