Product-Inset-Liquid-Spot-Sampler-300x300-3

Blackburn Coliwasa Liquid Spot Samplers take representative samples of hazardous wastes, liquids, slurry-type sludge's 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" stick-out on bottom for ready-fill sampling of viscous liquids and semi-liquids. Made of translucent, unmodified polypropylene for superior chemical resistance. Resists acids, alkalis, aromatic and aliphatic hydrocarbons, ketones, aldehydes, esters, oxidizers and glycols.

The sampler itself can serve as a sample container for non hazardous samples to eliminate the mess and inconvenience of sample transfer.
