The 1900K2 Extraction Kit comes with a 60 ml syringe, 3/16" O.D. EPDM tubing, 3/32" O.D. nylon tubing, and Luer connectors. This kit is designed for withdrawing collected samples from near-surface or column soil water samplers, most commonly 1900 and 1905. Not recommended for collecting from more than a couple of feet depth because of the limited vacuum provided by the syringe.
