Syringe 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, 0.22 microns / 0.45 microns
Material of shell: PP
Material of mambrane: PVDF
Performance: Polyvinylidene fluoride film with chemical stability and inert, suitable for chemical corrosive organic solvents, strong acid and alkali solution, high performance liquid chromatography analysis of the sample preparation. It has hydrophobic properties, can filter out air and Gas in the water. Polyvinylidene fluoride film is laminated on the support network, a strong strength and operability, can withstand 130 degrees high temperature.
