Corning Tube Insert 440 um Pore Size 24 mm Membrane Diameter 48 Inserts

The Corning 3480 Tube Insert is a specialized laboratory consumable designed to facilitate various cell-based assays and studies involving semi-permeable membranes. This insert is equipped with a membrane that has a 440 µm (micrometer) pore size and a 24 mm membrane diameter.

These tube inserts are typically designed to fit into the wells of standard multi-well plates, creating a two-compartment system. The membrane allows for the passage of nutrients, signaling molecules, or even cells through its pores, depending on the pore size, while maintaining a physical separation between different cell populations or experimental conditions. The 440 µm pore size is quite large for a cell culture membrane, suggesting it might be used for applications where cellular migration through larger pores is being studied, or for supporting organoids or tissues with nutrient exchange.

Corning tube inserts are valuable tools in cell biology, tissue engineering, and drug discovery research, enabling scientists to study cell-cell interactions, barrier functions, and cell migration in a controlled environment.
