These units are constructed of corrosion resistant Type 302 stainless steel. A weighted plunger with a FKM "O" ring seals the reservoir chamber at the bottom. Use a cable to lower sampler to desired depth. A negligible amount of liquid will enter during descent. Pull second cable to operate the sampling valve and release to reseal the chamber. This unit is not supplied with cables. We recommend use of a cable that can support 50 pounds or more and is made from stainless or PTFE coated stainless steel.
