LabExact PTFE Membrane Filter 0.45 um, 47 mm Diameter, 100 PK

Disposable sterile microbiological filtration monitor units are designed for efficient and reliable microbiological testing of liquid samples. Each unit has a 100 mL capacity and features a white, gridded mixed cellulose ester (MCE) membrane filter with a 0.45 µm pore size for effective capture of microorganisms. The printed grid aids in accurate colony counting and result interpretation. Supplied sterile and ready to use, these units help minimize contamination risk and preparation time in routine testing workflows. The non‑welded design supports easy handling and compatibility with ...

Disposable non-sterile PTFE hydrophobic filtration media syringe filters feature Luer-Lok™ and pressure fitting. They are ultrasonically bonded for reliability and the filter media type is clearly inscribed on barrel. Excellent unit-to-unit and lot-to-lot reproducibility and consistency. The unique concentric funnel shaped barrel increases volume and decreases back pressure. Permits optimal utilization of small sample volumes. PTFE membranes are inherently hydrophobic; they are ideal for the filtration of nonpolar liquids and gases and are very resistant to solvents as well as acids ...

The PTFE Membrane Filter features a 0.45 µm retention rating and a hydrophobic membrane designed for effective filtration of air, gases, and non‑aqueous or aggressive chemical solutions. PTFE offers outstanding chemical resistance and thermal stability, making this filter well suited for corrosive solvents, acids, and harsh laboratory environments. The 47 mm diameter provides a larger filtration area, supporting higher throughput and uniform flow in vacuum or pressure‑driven applications. Supplied non‑sterile in convenient 100‑count packs, these membrane filters are ideal for analytical, ...

The PTFE Membrane Filter is designed for reliable, high‑throughput filtration in demanding laboratory and industrial applications. Featuring a 0.80 µm retention rating and a hydrophobic PTFE membrane, it is well suited for air and gas monitoring, venting applications, and filtration of non‑aqueous or chemically aggressive liquids. PTFE provides exceptional chemical resistance and thermal stability, ensuring consistent performance in harsh environments. The large 90 mm diameter offers increased filtration surface area, supporting higher flow rates and extended service life. Supplied ...

Biologically inert mixtures of cellulose acetate and cellulose nitrate result in membranes with a smoother and more uniform surface than pure nitrocellulose filters. MCE is easier to handle and less likely to crack and fracture than traditional CN membranes. Pure surface, no additional smoothing treatment or surfactants.Non-sterile version is bright white with an accurate pore structure and highly regulated density for accuracy. Medium-fast flow rates with reproducible loading capacity. Clean-edge processing ensures easy separation from stack and less curl. Autoclavable.Use for ...
