Laboratory Syringe Filter PTFE Filter Membrane 25MM 0.45um hydrophilic PTFE microporous Needle Filter Spiral Membrane 100/PK

Syringe Filter Hydrophilic PTFE 25mm 0.45umSyringe filter applied to a small sample of laboratory filtration, adsorption of its small sample, thus ensuring the maximum recovery amount or a small amount of high-value samples, the filter housing is made of polypropylene material, ultrasonic welding, adhesive-free agents, and thus will not contaminate the sample. The filter needle with a mixed cellulose membrane (aqueous) or nylon membrane (organic), according to the nature of your sample selection, convenient and reliable.Specifications: OD is 25mm, 0.45 micron Material: Hydrophilic PTFEPackage: 100/PKPerformance: suitable for water and a variety of organic solvents, resistant to all solvents, low solubility. It has the characteristics of high permeability, high air flux, high particle retention rate, good temperature resistance, strong acid, alkali, organic solvent and oxidizer, aging resistance and non-sticking, nonflammability and non-toxic and biocompatibility. Its related products are widely used in chemical, pharmaceutical, environmental protection, electronics, food, energy and other fields. Note:This product does not hydrophobic.How to choose the right filter?1. Mixed fiber membrane (MCE) a mixture of cellulose nitrate and cellulose acetate made hydrophilic, chemical compatibility, high protein adsorption. For particle analysis, particle ideas, biochemical analysis, HPLC sample preparation and solvent filtration.2. Nylon membrane (NYLON) chemical compatibility is good, can be used under the conditions of a PH value to 12, applied to biological products, culture medium, sterile filtering the solution.3. Polyvinylidene difluoride membrane (PVDF) hydrophilic PVDF membrane bound protein is far less than nitrocellulose, nylon and PTFE filtration membrane is compatible with aqueous solutions and various organic solvents, broad applicability, oxidation resistance and heat resistance good preparation HPLC, GC

• Suitable for small sample of laboratory filtration, adsorption of the samples is very low, to ensure that the maximum amount of recovered samples.
• Housing made of polypropylene material, adhesive-free, does not contaminate the sample.
• Pins can facilitate the filtrate outlet pipe accurately trace injection bottles.
• Interchangeable syringe filter with a microporous membrane of different materials can be selected according to the nature of your sample.
