Cell Strainers fit on test tubes or conical tubes to isolate primary cells and work to obtain single-cell suspensions. They are usually color coded to help identify which of the cell strainers to use for various tube sizes. They are meant to replace a gauze filtration system in cell dissociation. They are used for preparing samples in stem cell, tissue-derived, primary cell culture, and flow cytometry cell procedures. They come in nonsterile and sterile versions. Cell strainers are made with evenly spaced pores of nylon mesh. Most common mesh sizes include 40 µm, 70 µm, and 100 µm to help isolate cells of different sizes. Some strainers have molded tabs or an extended lip to help with aseptic or sterile handling.

The precisely defined pore sizes ensure consistent and reproducible results across experiments.
Various Mesh Sizes
Cell strainers are available in a range of mesh sizes, allowing researchers to select the appropriate size for their specific application.
Compatibility
They are compatible with standard labware, such as 15 or 50 mL tubes, making them easy to integrate into existing laboratory workflows.
Type of Cell Strainer
Überstrainer
The Überstrainer goes beyond a typical cell strainer; it’s a sterile Sample Preparation Device designed to separate, isolate, concentrate, and process particles from complex or diluted suspensions. Its modular design offers versatility, and the air-tight screw cap with a Luer Lock connector allows the filtration of an unlimited amount of liquid. The Überstrainer can be easily separated from the device, fitting into a 50 ml tube and a 20 mm tissue plate cavity.
Syringe Strainer
Designed for large quantities, the Syringe Strainer is a sieving or filtration device that can be connected to a syringe or a tube. The screw cap with a Luer-Lock adaptor works under positive or negative pressure, providing flexibility in different experimental setups.
Membrane Strainer
Membrane Strainers offer a well-defined pore size exclusion limit (available with 1, 3, 5 & 8 μm pores), allowing precise filtration and detection of very small particles. These filters are non-hygroscopic, have low non-specific protein binding, and are biologically inert, making them suitable for various applications such as biological analysis, cytology, parasitology, and environmental analysis.
Re-Strainer (In-Line-Strainer)
The Re-Strainer is a filtration device with two Luer-Lock adaptors that can be used as an In-Line-Filter. Multiple Re-Strainers can be connected to form a filter cascade, offering the flexibility to handle high volumes of liquid and exclude or concentrate particles. The 6 ml recovery reservoir allows for easy access to recovered particles by unscrewing the cap.
Steel Basket Strainer
Made of fine stainless steel mesh, the steel basket strainer fits into standard 50 ml centrifuge tubes. Due to the chemical resistance of the steel, it is recommended for processes where plastic cell strainers are not suitable. The excellent mechanical stability of the steel basket strainer supports tissue dissociation, and it can be reused several times, with heat sterilization or autoclaving recommended.
Applications of Cell Strainer
Tissue Dissociation
Breaking down tissues into single cells for further analysis or culture.
Flow Cytometry
Analyzing single cells for various parameters, such as cell size, granularity, and fluorescence intensity.
Cell Culture Work
Ensuring an even distribution of cells in a flask or dish for optimal growth conditions.
Stem Cell Research
Isolating specific cell types for differentiation or transplantation studies.
Biopharmaceuticals
Separating and purifying microorganisms, cells, fragments, and insoluble impurities in biological preparations.
Diagnostic Testing
Filtering body fluids, such as bronchoalveolar lavage (BAL), urine, or plasma, to remove cell debris, mucus, or large particles before analysis.
Materials: Cell strainers are typically made of sturdy polypropylene frames with nylon mesh screens. The polypropylene frame provides structural support, while the nylon mesh acts as the filtration barrier.
Design: Some cell strainers feature advanced designs, such as stackable interlocking frames for tiered filtration, or unique geometries to ensure aseptic handling and eliminate contamination risks.
How to choose a cell filter
Pore Size
Choose based on the sample type and experiment goal. For general use, 70 µm is often the sweet spot. For larger cells or minimal debris, 100 µm may be suitable, while 40 µm is ideal for removing large aggregates.
Material
Nylon is preferred for most general lab applications due to its durability, while polyester is better for specialized chemical treatments.
Sterility
Ensure the cell strainer is sterile and individually packaged to prevent contamination.
Compatibility
Verify that the cell strainer fits standard labware (e.g., 15 or 50 mL tubes) for seamless integration into existing workflows.
