This stainless-steel sampling device allows you to retrieve a sample from the bottoms of storage tanks,
tank cars and drums in order to best detect contaminants. When monitoring tanks, it is important to
detect free water and sediment which reside at the bottom of the tank. If present, microbial
contamination will be in the fuel-water interface. Lower the device to the bottom of the tank. When the
device strikes the bottom, the plunger assembly opens to admit the sample. The plunger closes again when
the device is withdrawn, forming a tight seal.
