The Voss SingleSample® Coliwasa.

 Drum sampling made easy.


The Voss SingleSample® Coliwasa is constructed entirely of inert HDPE to resist almost all chemicals and solvents. The positive displacement, rod controlled valve (shown outside of the device above) features a set of four clamping fingers to assist in holding the valve shut until you are ready to transfer your sample to a container for transport.
