Pall® FluoroTrans® PVDF Transfer Membranes

• Sensitive Protein Detection with Low Background and Very Low Burnthrough
• Naturally hydrophobic polyvinylidene fluoride is ideal for a wide variety of protein-analysis applications. The family of FluoroTrans media are white, microporous solid phase supports that bind proteins tenaciously via hydrophobic interactions.
• High sensitivity for small peptides.
• High protein binding capacity. Typically absorbs 50% more protein than nylon or nitrocellulose.

FluoroTrans PVDF membrane is optimized for N-terminal protein sequencing. The medium demonstrates good signal-to-noise ratios with standard detection systems, and immobilized proteins can be used directly for sequencing, or visually detected with common staining reagents including Amido Black, Ponceau S, and colloidal gold. 

Pall® Acrodisc® Syringe Filters with Supor® Membrane

Syringe filters ideal for biological and general research.

• Large pore sizes for high throughput and fast flow rates
• Low protein binding to minimize sample loss
• Built in pre-filter for difficult to filter liquids

Supor® (polyethersulfone) membrane provides high throughput and fast flow rate. The filters of 0.2 and 0.45 μm pore sizes provide sterilization of small volumes of buffers, culture media, and additives. Low protein binding to minimize sample loss.

These Supor syringe filters are offered as recommended replacements for the discontinued HT Tuffyrn syringe filters.

Supor membrane is ideal to use for the filtration of general aqueous samples. The GxF/Supor membrane configuration features a a GxF multi-layer glass fiber prefilter, providing two to four times the throughput of standard prefilter devices. The multi-layer prefilter captures particulate rated from > 40 to 1 μm.
