Each features a special tapered fitment which serves as a check valve to close off the sampler and allow easy transfer to sample bottles with minimum loss. Made of high density, inert polyethylene, each coliwasa is individually decontaminated with Liquinox™ laboratory detergent and DI water rinse before assembled, and then individually packaged and sealed. 1,100 ml capacity, 1.5” I.D. x 42”L.
