Membrane filter TLPESB022254

hydrophiliclaboratoryfor the pharmaceutical industry

Product overview
The reinforced polyethersulfone (PES) flat membrane is a naturally hydrophilic supported membrane cast onto a reinforcing support for improved mechanical strength and thermal bonding. Designed for process and sterile filtration in medical and biopharmaceutical environments, it provides low protein binding and broad chemical compatibility.

Key features

• Low protein adsorption and low extractables
• High porosity with uniform pore distribution
• Consistent inter- and intra-lot performance
• Enhanced mechanical strength due to reinforced support
• Good chemical resistance to acids and alkalis
• Intrinsic hydrophilicity for efficient wetting and high flow rates
• Compatible with multiple sterilization methods: autoclave, EO and Gamma (parameters must be verified)
