Hydrophilic PTFE membrane filters have been approved by ISO9001 and all are imported from Germany and the US to ensure high quality. The vacuum membrane filter 0.45 μm is manufactured in 100,000 class cleaning room with various sizes, pore sizes, and diameters available in supply for different applications.

MS ® hydrophilic PTFE syringe filters are using special hydrophilic PTFE membrane as the filter medium. This material has a maximal chemical and pH resistance and optically clear when wet with water. Hydrophilic PTFE syringe filter is a versatile filter for aqueous and aggressive organic solvent-based solutions and especially ideal for HPLC

Phenex syringe filters are designed for efficient and rapid filtration of almost any solution prior to analysis, and are optimized for superior flow rates and high throughput. Proper membrane and size selection are the keys to choosing the best product to maintain the integrity of your sample components as well as to protect your system from

View Hydrophilic PTFE Membrane Filters View PTFE Syringe Filters View Hydrophilic PTFE Syringe Filters. Regenerated Cellulose (RC) Regenerated Cellulose is a hydrophilic, solvent resistant, low protein binding membrane. R C membrane is ideal for removing particulates from HPLC samples, prior to injection. This membrane is compatible with all

Hydrophobic PCTE membranes typically have insufficient water entry pressures for these applications and will allow liquid water to pass at pressures lower than required. Hydrophobic PTFE and PETE membrane filters have the highest water entry pressures for membrane filters and are commonly used for these applications.

Request Information. A key sample preparation technique, microfiltration removes micron-range particles or biological entities from fluids by passage through a microporous medium, such as a membrane filter. Merck, with over 50 years of filtration expertise, sets the industry standard for high-performance membrane technology for sample preparation.
