70 µm Cell Strainer

Balanced Filtration for Tissue Dissociation & Routine Cell Preparation

The 70 µm cell strainer is the most commonly used pore size in cell biology laboratories due to its balance of filtration efficiency and cell yield.

It is widely used for preparing single-cell suspensions from tissues and biological samples, providing consistent and reproducible results in routine laboratory workflows.

What Is a 70 µm Cell Strainer?

A 70 µm cell strainer is a standard laboratory filter used to separate single cells from tissue debris during sample preparation.

Filtration Mechanism

During sample processing:

• Tissue suspensions pass through a uniform nylon mesh
• Larger debris and cell clumps are retained on the surface
• Individual cells pass through efficiently
• Smooth flow reduces clogging during repeated use

This structure ensures stable filtration performance across a wide range of biological samples.

Key Applications

• Tissue dissociation (spleen, liver, tumor, lymphoid tissues)
• Primary cell isolation and purification
• Cell culture preparation and sample cleaning
• Pre-filtration for flow cytometry analysis
• Immunology and biomedical research workflows

Performance Advantages

• Balanced filtration efficiency and high cell recovery
• Suitable for most mammalian cell types
• Reduced clogging during routine processing
• Consistent pore size for reproducible experimental results
• Reliable performance across diverse sample conditions

70 µm vs Other Cell Strainer Sizes

• Compared with 40 µm Cell Strainer → higher cell yield, less restrictive filtration
• Compared with 100 µm Cell Strainer → better removal of fine tissue debris and impurities

Best use case:
The 70 µm cell strainer is the universal standard size for most cell isolation and tissue dissociation workflows.

Workflow Compatibility

For complete cell preparation workflows:

• For finer purification: use 40 µm Cell Strainer
• For higher yield and large tissue samples: use 100 µm Cell Strainer
