親水性 PDVF 0.02μm 過濾器(小飛碟) Hydrophilic PVDF 0.02μm Syringe Filter
品牌 產品編號 品名 規格 尺寸 CNW GS-2.CF7103.0001 樣品過濾器 親水性 PVDF 0.02 um, 100個 / 盒 13mm Syringe Filter
EN 71-3:2013 (E) 方法中，要求用0.45或0.22μm過濾器過濾樣品。但是有的小顆粒能通過上述過濾器，(如一些混濁溶液或有色過濾液等)。這可能導致在某些情況下遷移量測量值不準確，因為測量結果不僅包含遷移元素，還包括一些化學吸附在懸浮顆粒上的元素。如果有這種情況發生，利用孔徑0.02μm過濾器重新過濾溶液。如果無法重新過濾，重複遷移過程和分離步驟，最後再用孔徑0.02μm過濾器過濾。 針對目前市場上能夠提供0.02μm過濾器的廠商非常少，即使能提供，價格也非常昂貴的情況下，廣大客戶求而不得，為了滿足客戶的使用需求及經濟成本，為大家提供孔徑為0.02μm的親水性PVDF過濾器。
In EN 71-3: 2013(E) method, it requires using 0.45 or 0.22um syringe filter to filter samples. But some particles can pass 0.45 or 0.22 filters (Such as feculent solution and colored filtrate). It may cause incorrect test value of migration in some circumstance. Because test result includes not only migratory elements, but also elements chemisorption to particle. If this condition occurs, using pore size 0.02um syringe filter to re-filter samples. If it cannot be re-filtered, repeat migration process and the separation, and finally filter again with pore size 0.02um syringe filter. For there are few manufacturers can provide 0.02um syringe filter in current market, even if available, the price is very expensive. To meet customers needs and reduce their cost, CNW provides pore size 0.02um syringe filter with great quality and competitive price.
