Laboratory used millipore polypropylene/pp membrane filters microporous membrane

Nylon film (NB6/N66): A continuous film forming machine is used to form a casting solution composed of a nylon chip, a solvent and a pore-forming additive on both sides and a polyester nonwoven fabric, and is mutually converted. The mechanical strength of the film is high, the tensile strength is high, the longitudinal direction is greater than 250, the lateral direction is greater than 150, and the film length is optional. Currently, the width can be as wide as 320 mm. Therefore, it is very suitable for making a folding filter or a plate and frame filter device with high precision filling. (referred to as organic filter, can be divided into enhanced and non-reinforced)

Good temperature resistance, can withstand 121 ° C saturated steam hot pressure sterilization for 30min. It has good chemical stability and can withstand various organic and inorganic substances such as dilute acid, dilute alkali, alcohol, oil, carbon compound and halogenated hydrogen.

• Individual package with pre-sterilization for improving of testing reliability
• Gamma ray sterilization with zero residual
• Imported medical dialysis package

Parameter:

Polytetrathene film (PTFE): Made of PTFE film and imported polypropylene material by uniaxial stretching method. It is highly chemically compatible and is suitable for filtration of all organic solvents and highly corrosive chemicals.

Glass Cellulose Membrane (GF): The glass fiber membrane is chemically **, contains no binder, and is made of 100% boron ** glass fiber. It has a capillary fiber mechanism, which can absorb more water than the same cellulose filter paper, and has a fast flow rate and high temperature resistance.

Mixed cellulose ester film (CN-CA): The fiber is prepared by converting a casting solution composed of nitrate, cellulose diacetate, a solvent, and a pore-forming additive by a continuous film forming machine. The pore size is relatively uniform, the porosity is high, no medium is detached, the texture is thin, the resistance is small, the filtration speed is fast, the adsorption is very small, the use price is low, but the organic solution and the strong acid and alkali solution are not resistant.
