Supor® PES Membrane Disc Filters

High flow rate membrane optimized for biological, pharmaceutical, and sterilizing filtration requirements

• Fast filtration with superior flow rates and high throughputs. 
• Low protein binding and extensive drug compatibility for critical applications.
• Saves time and money with fewer filter changes per sample volume.
• 142 and 293 mm discs feature printed tab for instant recognition of pore size and lot number.
• May be sterilized by gamma irradiation, EtO, or autoclaving.

• Suited for biological, pharmaceutical, and sterilizing filtration requirements.
• Available for microbiological analysis in individual sterile packaging.

Sterilization

Provided non-sterile. Can be sterilized by autoclaving at 121 - 123 °C (250 - 253 °F) for 30 min. PN 63025, 5010, and 66234 are sterilized by gamma irradiation.

Supor Membrane is Low in Biomolecule Binding

¹²⁵I-labeled BSA (1.6 µg) or ³²P-labeled DNA (500 ng) was diluted to 5 mL in PBS (BSA) or Tris-EDTA (DNA) and filtered through a 13 mm disc of the indicated membrane. Filtration was carried out using a 10 mL syringe at a flow rate of 1.0 mL/minute. Binding was determined by comparing the amount of radioactivity remaining in the membrane (triplicate) to the activity of the starting material by counting the disc or solution in a scintillation counter. Biodyne® B membrane is designed for biomolecule binding and was used as a positive control.

Membrane Water Flow Rate

Supor polyethersulfone membrane flow rate outperfomrs nylon and PVDF membranes of the same pore size (0.2µm).
