The cell strainer cap for a FACS tube (fluorescence-activated cell sorting tube) is a important part that filter out unwanted debris, clumps, cells from the cell suspension before running it through a flow cytometer or FACS machine. These caps typically have a built-in filter mesh that acts as a strainer, allowing the passage of single cells whilekeeping larger particles. They are designed to fit securely onto the top of a FACS tube and provide a convenient way to filter the sample directly into the tube.
Share Filters' cell strainers are manufactured from precise nylon filter mesh with evenly spaced mesh pores and popypropylene(PP) surport cage. Available in 5μm, 10μm, 20μm, 30μm, 40μm, 70μm, 100μm, 200µm and color-coded mesh variants. The caps with strainers for 12x75mm (5ml) tubes offer vented positions.

Choosing the right cell strainer depends on what micron of cell and size test or flow tube that the sample is in. Once these are determined, the cell strainer cap fits right on the top of the tube tightly, so that all the material in the tube must pass through the strainer.
