Coliwasa Waste Samplers Comply with EPA Regulations and Methods
Coliwasa Waste Samplers allow you to take representative samples of hazardous wastes, liquids, slurry-type sludges and semi-solids from top to bottom of buckets, barrels, tanks or tankers. Also great for Q.A. and process sampling, Samplers comply with EPA regulations and methods.
Each patented, contamination-free Coliwasa (9/16" or 1" dia.) has a 2"L stick-out on 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 Coliwasa Waste Sampler itself can serve as a sample container for nonhazardous samples to eliminate the mess and inconvenience of sample transfer. Neoprene stoppers have PTFE film coating for improved stick resistance. Ethanol Coliwasas have silicone stoppers for ethanol compatibility.
PTFE Coupler Set allows you to combine any two of the five 1" I.D. Coliwasa types together to increase sampler length.
Purge-Squeegee Kits have a unique inside-outside squeegee attachment that cleans tube while making extraction.
