Coliwasa Samplers: The FDS Series
The Fluid Disposable Sampler series Coliwasa (Composite Liquid Waste Sampler) by SELA, is a very safe sampling device with the concerns of worker safety and site appearance in mind, due to shattered sampling devices eliminated in the product. These samplers are manufactured in two styles and they come in various lengths, with custom lengths available as well. The two styles are Polypropylene (PP) and RPVC plastic. All FDS series samplers have a polypropylene plunger in the bottom to form a tight seal in the sampler bottom. The plunger is attached to ¼” inch PP rod for operation, with the top of the rod bent at a 90 0 angle. The tube top is cut at an angle to allow valve to be “locked” in the closed position to prevent accidental release.
FDS DESCRIPTION: tube size, wall thickness, and specimen size collected are listed on page 3 for all items. Samplers are made of FDA grade polypropylene. If denoted with “C” suffix, of clear RPVC.
