Cylindrical filter paper No. 88R (ID 22mm OD 25mm L 90mm) 10 pieces 35810250 1 box (10 pieces)

This cylindrical filter paper is made entirely of fine silica fibers and can withstand high temperatures up to 1000°C. It does not use an alumina binder and has the advantage of being less reactive with acid gases such as SOx and NOx and sulfuric acid mist. It is mainly used to measure dust concentration in exhaust gas. *This is a dust sampler for gas. It cannot be used for filtering liquids. *When filtering gas, the filter may be damaged if it gets wet. In such a case, we recommend using No. 89 or No. 89S, which have water repellent properties. Composition: Silica fiber Weight (g/piece): 1.6 Thickness (mm): 2.2 Pressure loss (kPa): 0.44 Collection efficiency (0.3μm DOP%): >99.9 Maximum operating temperature (℃): 1000 *Pressure loss: Value when using a product with OD 25mmL 90mm and an air flow rate of 5L/min. *Collection efficiency: Collection efficiency when air containing dispersed 0.3μm dioctyl phthalate particles is filtered using a product with an OD of 25mm and length of 90mm at an air flow rate of 5L/min.
