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 ...

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 ...

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 ...

Features: PTFE membranes are inherently hydrophobic; they are ideal for the filtration of nonpolar liquids and gases. Very resistant to solvents as well as acids or bases. Can be made more hydrophilic by flushing with alcohol, followed by water Used for filtering and de-gassing chromatography solvents Permits optimal utilization of small sample volumes Excellent chemical compatibility for filtering harsh chemicals that destroy other membrane materials Moisture barrier for venting applications and vacuum pump line protection Ideal for aerosol sampling Filter viscous organic based HPLC ...
