The Cole-Parmer® Essentials air-lock free cell strainers provide a fast and easy-to-use solution for detaching, isolating, and straining cells from clusters and tissues. The advanced housing enhances performance and reduces processing time by eliminating the “air-lock” effect. Improved aeration allows air to escape while filtrate is entering the tube, preventing messy spillovers.

The polypropylene frame supports a nylon mesh that is available in three color-coded porosities— blue 40 µm, white 70 µm, and blue 100 µm. The molded grip ensures aseptic handling and eliminates the contamination risks associated with fingers contacting the filtered suspension, mesh, or interior surfaces. The sterile strainer can easily be removed from the special blister packaging without touching its interior surface or mesh.

These cell strainers can be directly attached to the top of a 50 mL tube or attached to the reducing adapter that attaches to 5- or 15-mL tubes. Built-in support tabs and four 1.5 mm feet are designed to fit in a 6-well plate.
