Cellulose Acetate (CA) Membrane Filter 47 mm | white (w/o grid) Cellulose acetate (CA) membrane | Hydro Diameter: 47 mm Color Grid Color: white (w/o grid) Material: Cellulose acetate (CA) membrane Reaction to water: Hydrophilic Type: Membrane filter Packaging: Non-sterile, bulk packed Pore size: 0,45 µm Pack size: 100 Cellulose acetat membranes combine high flow rates and thermal stability with very low adsorption characteristics and are therefore excellently suited for use in pressure filtration devices. The membrane with 0.2µm is the filter of choice for sterile filtration of aqueous solutions, such as nutrient media, buffers and sera. The results of publications on adsorption are difficult to correlate, as mostly different test substances, conditions and detection methods were used, and the membranes were tested without previously being sterilized. Adsorption: BSA 2.9 bar (42 psi) when measured with an automatic integrity tester 0,45 µm bubble point: 1,9 bar 0,65 µm Pore size: 1.3bar (18.9psi) 0,8 µm: 0.8bar (11.6psi) 1,2 µm bubble point: 0,6 bar 5 µm bubble point: 0,3 bar 0.2 µm: 24ml/min/bar 0,45 µm: 69ml/min/bar 0,65 µm Pore size: 130ml/min/bar 0,8 µm: 200ml/min/bar Sterilisation: By autoclaving at 121 °C or 134 °C, gamma radiation 25 kGy, dry heat or ethvlene oxid Thickness acc.
