Polyester Drain Discs

Polyester Drain Discs are for use with membrane hardware where extra support is needed for improved flow rate and throughput. The polyester drain disc is binder-free and has a thickness of 100 µm. It provides a flat surface to eliminate filter tearing or rupturing. It is also used as a separator between membrane layers in serial stack filtration applications. This chemically inert support disc is available in a variety of diameters for use in a range of devices.

Applications
• General laboratory microfiltration
• Quality control and sterility testing
• Removal of particulates from HPLC solvents
• Tissue culture media filtration
