Featuring a naturally hydrophilic polyethersulfone (PES) membrane with a 0.45um pore size, these 25mm syringe filters deliver fast, low-binding filtration of aqueous and organic solutions. The 0.45um PES membrane is housed within a transparent polypropylene housing measuring 33mm in diameter, with a Female Luer Lock inlet and Male Luer Slip outlet for direct connection to standard syringes. Supplied nonsterile in packs of 100.
Key PES Membrane Characteristics
- Naturally hydrophilic structure wets out readily for rapid filtration of aqueous and alcohol-based solutions without pre-wetting.
- Low protein binding helps preserve sample integrity and analyte recovery.
- 0.45um pore size provides reliable clarification and particulate removal ahead of analytical workflows.
- Broad compatibility with aqueous and organic samples makes it a versatile choice for routine sample preparation.
Key Construction Characteristics
- Transparent polypropylene housing with a 33mm housing diameter and a 25mm membrane diameter providing a 4.6 cm² effective filtration area.
- Female Luer Lock inlet and Male Luer Slip outlet (Luer-Lok/Luer Slip) for secure syringe attachment.
- Holdup volume of less than 100 microliters to minimize sample loss.
- Maximum operating temperature of 90°C and maximum operating pressure of 80 psi.
- Nonsterile, supplied 100 per pack.
These syringe filters provide consistent, reproducible filtration that protects downstream instruments and columns. The bidirectionally supported membrane allows both sample injection and aspiration, while the low holdup volume conserves precious or limited samples. The result is clean, particle-free filtrate suitable for demanding analytical applications.
