PTFE filter paper PF-050 47mm 20 pieces 38501047 1 box (20 pieces)

It can be used stably and continuously in a temperature range of -120 to 260°C, and can also be sterilized by autoclave, dry heat, or ethylene oxide gas. It has excellent chemical resistance and is not affected by acids, alkalis, oxidizing agents, organic solvents, etc., and can be used with most chemicals except for special chemicals such as fluorine gas, chlorine trifluoride, and molten alkali metals under high temperature and pressure. Because it is hydrophobic (has the ability to repel water), it is less affected by humidity during gas filtration, and it hardly adsorbs acidic gases. A special process is used during filter manufacturing, so there is almost no fiber coming off the filter. After filtration, the filter can be washed with chemicals so that it can be reused repeatedly. It has a low coefficient of friction, electrical properties, non-adhesiveness, and releasability, so the residue on the filter after filtration can be easily collected compared to cellulose filter paper. Dimensions (mm): 47 Mass (g/m^2): 210 Thickness (mm): 0.36 Porosity (%): 73 Pressure loss (kPa): 0.26 Collection efficiency (0.3μm DOP%): 85.0 Retention particle size (μm): 5 Water repellency (kPa): ＞4.9 *Pressure loss: Value when air flow rate is 5cm/s. *Collection efficiency: Collection efficiency when air containing dispersed 0.3 μm dioctyl phthalate particles is filtered at an air flow rate of 5 cm/s. *Retained particle size: Calculated from the captured particle size when standard particles in methyl alcohol are filtered at a filtration rate of 1.0 kL/h・m^2. *Water repellency: The pressure required for water to pass through.
