SIBATA SCIENTIFIC TECHNOLOGY Cellulose acetate type membrane filter

Since it can remove microorganisms and fine particles contained in liquids and gases, it can be used in an extremely wide range of fields such as electronics, pharmaceuticals, foods, medicine, and physics and chemistry. Compared to the cellulose mixed ester type, it has excellent strength and is easy to handle when set. It can withstand autoclave sterilization, ethylene oxide gas sterilization, and dry heat sterilization (180 ° C). Since the material is inert, the filter fluid components such as proteins are hardly adsorbed on the filter. Compared to the cellulose mixed ester type, it is more resistant to alcohols.
* Water: 25 ° C distilled water filtered through a 0.10 μm membrane filter is filtered under a reduced pressure of -0.069 MPa, and the flow rate is indicated by the number of mL per ^{1 cm 2 per minute.}
* Air: Air at 25 ° C is filtered under the condition of a differential pressure of 0.069MPa, and the flow rate is displayed as the number of L per minute per ^{1cm 2.}
* Bubble point: The pressure at the point where continuous bubbles start to appear through a sample (membrane filter) completely wet with water, and the unit is expressed in MPa.
