Cell Strainers

Kelabscience supplies disposable cell strainers for preparing single-cell suspensions, removing cell aggregates, and filtering tissue-derived samples. We work with laboratories, research institutions, and distributors to provide suitable cell filtration consumables for routine sample preparation, cell culture, and downstream cellular analysis.

Our cell strainers are available in three mesh sizes: 40 µm, 70 µm, and 100 µm. Each strainer consists of a nylon filtration mesh supported by a polypropylene (PP) frame, designed to fit compatible 50 mL conical centrifuge tubes. The integrated handling tab allows users to conveniently position and remove the strainer during sample preparation.

For related sample collection and handling products, explore our Lab Centrifuge Tubes.

The nylon mesh helps separate larger tissue fragments, cell aggregates, and debris from cell suspensions. Different mesh openings allow customers to select appropriate filtration conditions according to their sample characteristics, aggregate size, and desired cell recovery.

Available Product Configurations

• Mesh Sizes: 40 µm, 70 µm, and 100 µm for different cell suspension filtration requirements.

• Mesh Material: Nylon mesh for size-based filtration of cell suspensions and tissue-derived samples.

• Frame Material: Polypropylene (PP) construction with an integrated handling tab for convenient positioning and removal.

• Tube Compatibility: Designed for use with compatible 50 mL conical centrifuge tubes.

• Frame Colors: Purple, orange, and green, with specific colors confirmed according to the selected mesh size.

• Sterility: Supplied sterile for laboratory sample preparation workflows.

• Packaging: Individually packaged for convenient handling and single-use applications.

Cell Filtration and Sample Preparation

Cell strainers are commonly used following mechanical or enzymatic tissue dissociation to remove larger aggregates and residual tissue fragments before downstream experiments.

The selection of mesh size depends on the properties of the sample and the intended application. A smaller mesh opening may help remove finer aggregates but can also increase cell retention or clogging for certain samples. Larger mesh openings are generally useful for coarser filtration and samples containing larger tissue fragments.

For cell culture preparation, flow cytometry sample processing, or cell counting, choosing an appropriate mesh size can help reduce unwanted aggregates. However, filtration performance and cell recovery depend on the sample composition and handling procedure.

For workflows that proceed to adherent cell cultivation, explore our Cell Culture Flasks for subsequent cell maintenance and expansion.

Bulk Supply and Procurement Support

At Kelabscience, we understand that laboratories and distributors require clear mesh specifications, consistent product configurations, and suitable packaging when sourcing cell preparation consumables.

We supply 40 µm, 70 µm, and 100 µm nylon cell strainers with polypropylene frames, designed for compatible 50 mL centrifuge tubes. All three mesh sizes are available for bulk purchasing inquiries.

Customers can contact Kelabscience with their required mesh size, estimated order quantity, and any specific packaging or product configuration requirements. Our team will help confirm the appropriate product details and provide quotation information.
