Corning 431096 康宁 250mL真空过滤系统 0.22um孔径 PES（聚醚砜）膜 50mm直径滤膜 灭菌 单个包装 1个/包 12包/箱，，此产品为易碎品，整箱销售。
- PES（聚醚砜膜、黄色标记）：最适用于细胞培养基的过滤，由于它对蛋白与核酸的低吸附，因而流动效率最好
- PES膜无湿润剂，蛋白结合率很低，DNA结合率很低，化学耐受性低
- 直角软管接头简化了真空线附件
- 接收瓶易握的两侧的特点，提高了处理能力
- 接收瓶的盖是灭菌且单独包装的

NEW! Over the next several months Corning is introducing a new square filter support with a higher capacity Polyethersulfone (PES) membrane for greater filtering performance. Continue ordering the same catalog numbers you are currently using and the new improved filters will show up in your lab as soon as they are available. These new 250mL Systems are designed for filtering and storing cell culture media, biological fluids and other aqueous solutions. The new system consists of a 250mL polystyrene receiver bottle and filter funnel with a 0.22μm Pore 19.6cm2 PES membrane and a polyethylene neck adaptor with hose connector. |
- Polyethersulfone (PES) membranes provide the fastest flow rates, the lowest protein binding and low extractables and are best for filtering cell culture media.
- 250mL receiver bottles feature easy grip sides for improved handling.
- Additional storage bottles can be purchased to increase capacity.
- Bottle caps are supplied sterile and individually packaged. -
- Angled hose connector simplifies vacuum line attachment.
- Individually packaged, sterile and certified nonpyrogenic.
- Each system has the membrane material and pore size printed on the unit and is color-coded by membrane type for easy product identification.
- Expiration date appears on the filter funnel and shipping boxes.
- Expiration date of the membrane is three years from the time the product is manufactured.
