Supor 800 Membrane Disc Filters, 0.8um - 293mm, No Tab, 25/Pk SKU: 66556

Supor (PES) Membrane Filters - 66556

The Pall 66556 combines a controlled pore size distribution with low extractable levels, ensuring the data accuracy that sensitive analytical methods require. High flow rate performance reduces processing time in vacuum filtration setups, making Supor the preferred membrane for laboratories filtering multiple liters per session. Each membrane disc reflects a manufacturing standard where retention characteristics, physical integrity, and dimensional accuracy are verified before release.

Material Specifications

• Supplied in bulk non-sterile packaging, offering an economical option for routine clarification and general laboratory filtration tasks.
• Broad chemical compatibility across pH 1–14 enables Supor membranes to process acidic, neutral, and alkaline solutions without membrane degradation.
• Asymmetric pore architecture concentrates the retentive skin at the upstream surface while maintaining an open substructure for sustained throughput under vacuum or pressure.
• Materials of construction maintain their mechanical and chemical properties at temperatures up to 55°C, supporting heated filtration protocols.
• Supor polyethersulfone membranes deliver the highest flow rates in the PES membrane class, reducing vacuum filtration time for high-volume laboratory applications.

Reproducible particle counting starts with a membrane surface that captures particles uniformly. The pore consistency documented above ensures your counts reflect the sample, not filter variation. Specifically, the chemical compatibility range documented for this device allows you to verify suitability for your specific sample matrix before processing, avoiding the mid-filtration failures that waste both sample and time. Take control of your sample preparation variables and ensure that your data reflects the true nature of your work, rather than the quality of your consumables.
