After a sample has been collected, lower and press lightly on the inner tube to seat the PTFE seal, locking the sample column into place. This unit is 7/8" by 42" long, has a tapered bottom with an approximately 1/2" diameter opening and a sample capacity of 200mL. Disposable units are prescored for disposal after a single use.
