Voss SingleSample® Drum Coliwasa (12 Units Per Case)

Voss SingleSample® Drum Coliwasa – Disposable Liquid Sampler (Case of 12)

The Voss SingleSample® Drum Coliwasa is a disposable liquid sampling device designed to collect representative, vertical column samples from drums and tanks containing stratified or immiscible liquids. Ideal for environmental sampling, waste profiling, and regulatory compliance, each Coliwasa allows for safe, contamination-free sampling of hazardous, corrosive, or incompatible liquids.

Made from chemically resistant HDPE or polycarbonate, each sampler includes an internal sealing rod and O-ring plunger that locks in the liquid column once withdrawn—preventing leakage and ensuring an accurate cross-section of the drum contents.

This case includes 12 individually packaged SingleSample® Coliwasa units, each pre-assembled and ready for immediate use in the field or lab. The disposable design eliminates cross-contamination risk and simplifies hazardous waste handling procedures.
