LabExact Grade CFP44 Qualitative Cellulose Filter Paper 0.165 mm Thick, 7.0 cm Dia., 3 um, 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, ...

Grade TSS is a Binderless high efficiency (HEPA type) filter medium with particle retention of 1.50um. Liquid filtration properties have been specifically designed for EPA Methods 2540C and 2540D for testing dissolved and suspended solids in water and wastewater. High flow rate with high capacity. Binderless borosilicate glass fiber media has no added extractables to aid in the elimination of sample contamination. Excellent wet strength. Other common applications include gravimetric analysis of air pollutants, membrane support pads, membrane prefilters, clarification of reagent and buffer ...
