Modular and reusable
These products have been specially designed for the hazardous waste and groundwater markets and can be used to sample liquid or sludge from drums, tank cars, lagoons, lakes, rivers and storage tanks. Sample types include general liquids, petroleum products, sludge / waste / viscous fluids.
The uniquely designed top spin bar and bottom valve plate mechanism provides a positive seal for sample retention along with greater control for releasing the sample. The modular design also adds flexibility by enabling the connection of several sections to form a larger sampling unit up to 20 feet. To use the coliwasa, simply spin the open-top locking handle, insert slowly into the drum to collect liquid column, pull the top handle to seat the bottom valve plate, and spin the top handle closed, trapping the column in sampler. Material: PVC. Dimensions: 1-3/8" ID x 1-5/8" OD. The coliwasa units come with a 48" long cleaning brush.
