Barrel Coliwasa, 460mL, 1” dia. x 39”L

460mL, 1” dia. x 39”L Take representative samples of hazardous wastes, liquids, slurry-type sludges and semi-solids from top to bottom of barrels, tanks or tankers. Also great for Q.A. and process sampling. Each patented, contamination-free Coliwasa (9/16” or 1” dia.) has a 2”L stick-out on the bottom for ready-fill sampling of viscous liquids and semi-liquids. Translucent, unmodified polypropylene provides superior resistance to acids, alkalis, aromatic and aliphatic hydrocarbons, ketones, aldehydes, esters, oxidizers and glycols. Break-resistant Coliwasas clamp shut to avoid spillage. The Sampler itself can serve as a container for nonhazardous samples to eliminate the mess and inconvenience of sample transfer. Neoprene stoppers have PTFE film coating for improved stick resistance.
