Product Description
Collect a true top-to-bottom sample from drums and tanks of stratified liquids. The Coliwasa design captures the full liquid column, so separate layers are represented in the sample, and a check valve prevents loss while the tube is withdrawn and transferred.
This listing is for Kimble catalog number 76100-200: KIMAX Coliwasa Tube, 200 mL, Case of 12. The two-part tube is borosilicate glass 3.3, with a 22 mm OD outer tube and a 9 mm OD inner tube about 1220 mm long. A ball in the lower end acts as a check valve. Both parts are prescored, so the unit snaps apart easily for safe disposal. Capacity is 200 mL; packed 12 per case. Order it from LIGHT LABS and keep your lab stocked with genuine DWK Life Sciences products.
