一般描述
一、产品信息
1、名称：一次性真空滤杯，一次性真空式过滤器，真空过滤系统
2、滤膜材质：PES（聚醚砜）、PVDF（亲水聚四氟乙烯 ）、CA(醋酸纤维）、NY(尼龙）
3、包装：真空滤杯1箱（1只/包，12只/箱）
二、产品描述
一次性真空过滤装置对于组织培养介质、生物学流体中大体积样品的分离和纯化有很大用处。整套装置包括膜片、由连接器连接的一个有刻度的聚苯乙烯(PS)材质的透明漏斗和一个接收瓶。一次性真空过滤器利用真空泵提供压力差，用于组织培养液和其他实验室流体溶液的大量过滤，样品处理可达数升，过滤后的样品可直接以无菌的收集瓶保存。有三种形式：完全过滤/存储单元、顶端滤器和接收瓶。
三、用途
1、用于组织培养液、生物流体、定位缓冲液的过滤
2、过滤细胞培养介质和其它的水溶液
3、无法高压灭菌的溶液的无菌过滤
4、提供灭菌过滤以及采用玻璃纤维预过滤膜过滤难过滤的水溶液
四、滤膜选择
PES聚醚砜树脂膜：亲水性，低蛋白结合<1.5%，高流速，高孔隙率，适用于大多数的生物水性溶液，适合过滤细胞培养基。
CA醋酸纤维素膜：亲水性，不耐强酸碱溶液，适合于生物样品中的蛋白质和水溶液的过滤，如血清培养基过滤等。
PVDF聚偏氟乙烯膜：亲水性，低蛋白结合，适用于一般的生物过滤，不适用于强腐蚀性液体的过滤，不耐DMSO。
Nylon尼龙膜：亲水性，高蛋白结合，适合不含蛋白的水溶液和有机溶液等，耐酒精和DMSO等。

Product Information
1. Name: disposable vacuum filter cup, disposable vacuum filter, vacuum filtration system
2. Membrane material: PES (polyethersulfone), PVDF (hydrophilic polytetrafluoroethylene), CA (acetate fiber), NY (nylon)
3. Packing: 1 box of vacuum filter cups (1 piece/pack, 12 pieces/box)
Product description
Disposable vacuum filtration devices are useful for the separation and purification of large volume samples from tissue culture media, biological fluids. The complete set includes a diaphragm, a graduated polystyrene (PS) transparent funnel and a receiving bottle connected by a connector. Disposable vacuum filters utilize a vacuum pump to provide pressure differentials and are used for bulk filtration of tissue culture and other laboratory fluid solutions. Samples can be processed up to several liters. The filtered samples can be stored directly in sterile collection bottles. There are three forms: full filter/storage unit, top filter and receiver bottle.
Application：
1. Filtration of tissue culture fluids, biological fluids, positioning buffers
2. Filtration of cell culture media and other aqueous solutions
3. Sterile filtration of solutions that cannot be autoclaved
4. Provide sterilization filtration and use glass fiber pre-filter membrane to filter difficult-to-filter aqueous solutions
Fourth, filter membrane selection
PES polyethersulfone resin membrane: hydrophilic, low protein binding <1.5%, high flow rate, high porosity, suitable for most biological aqueous solutions, suitable for filtration of cell culture media.
CA cellulose acetate membrane: hydrophilic, not resistant to strong acid and alkali solutions, suitable for filtration of proteins and aqueous solutions in biological samples, such as serum medium filtration, etc.
PVDF polyvinylidene fluoride membrane: hydrophilic, low protein binding, suitable for general biological filtration, not suitable for filtration of strong corrosive liquids, not resistant to DMSO.
Nylon nylon membrane: hydrophilic, high protein binding, suitable for protein-free aqueous and organic solutions, etc., resistant to alcohol and DMSO, etc.
Features
1. One-time use, pre-sterilized by gamma rays
2. Bactericidal filtration efficiency (0.22μm): LRV＞7 Deficient Brevimonas, ATCC19146, ASTM bacterial challenge test
3. No heat source, no surfactant, very low extract
4. Very low protein adsorption rate <1.5% (PES)
5. Ultra-high flow rate and flux, filter liquid faster, more
6. The GL45 interface is suitable for routine laboratory receiving containers.
7. Ergonomic design, the upper and lower containers have scales, making the filtration more convenient and easy to operate
8. Glass fiber membrane (GF) can be added as pre-filtration as required to filter more liquids
