The pore size of the membrane: * pore size 0.45μm membrane: used for conventional sample mobile phase filtration, can meet the general chromatographic requirements. Such as: chromatography system for 3μm or larger particle size fillers. * 0.22μm pore size filter: it can remove the requirements of very fine particles in the sample and mobile phase. Such as: chromatography system for <3μm packing. *Aperture 1-5μm filter: It is often used for turbid solution which is difficult to handle. It can be pre-filtered with 1-5μm filter and then filtered with corresponding filter. 2. Characteristics of the filtered sample: A: hydrophilic sample: a hydrophilic membrane is suitable, which is suitable for filtering water as a matrix solution. Such as: tap water, surface water, available filter membranes: water film (mixed cellulose ester), nylon film (polyamide).
Overview and characteristics: Polypropylene microporous membrane is made of polypropylene microfiber hot melt bonded together. It is a membrane material for deep filtration. It has the following characteristics: food grade isotactic polypropylene is used as raw material. , no additives in the whole process of production; stable physical and chemical properties, good compatibility; with a series of pore diameters, high porosity, large amount of dirt, recoil and high temperature disinfection; good pressure resistance
Accuracy: 0.1um, 0.22um, 0.45um, 0.65um-100um
Note: (1) The nominal accuracy is detected by bubbling pressure method, and the detection reagent is anhydrous ethanol. (2) The flow rate is the initial water pressure of 0.1 MPa, the film thickness is 0.18 mm-0.35 mm, and the water flow rate under the condition of raw water turbidity 3 NTU detection. (3) The above parameters can be adjusted according to the specific requirements of customers.
3, size: diameter (mm) 50, 60, 100, 150, 200, 300, 400, 500, 550, 600, 800, 1000, 1200, 200 × 200, 300 × 300, 400 × 400, 500 × 500 600×600
Instructions for use
1. PP filter membrane is made of polymer material, non-toxic, and can be widely used in medicine, chemical, food, beverage and other fields.
2, PP filter membrane is excellent in chemical resistance, it can be resistant to acid, alkali and solvent, including polar solvents (except benzene xylene).
3, PP filter membrane temperature resistance, can be 121 ° C, 30 minutes hot pressing disinfection, working temperature below 100 ° C.
4, PP filter membrane strength, no deformation, no media shedding, no re-contamination. It can be used after infiltration with 70% ethanol for several minutes before use.
5, PP filter is a deep filter, the resistance is small, the flow rate is fast, in the case of low pressure difference, it can reach higher flow, long service life, especially suitable for differential filtration, high viscosity, filtration of many suspended materials, filtration time The longer the filter, the higher the filtering accuracy.
6, PP filter membrane is hydrophilic, especially for liquid filtration or gas filtration.
