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

In HPLC, particulates and microbial growth in mobile phase buffers and samples can damage expensive HPLC equipment such as pumps, valves, columns and detectors. They can also lead to erratic analytical results. Pre-filtering samples and mobile phases prior to analysis can help prevent column and frit blockage, abnormally high operating pressures, and can undue wear on valve and injector seals.

Verex Filter Vials are designed to provide simple and rapid sample preparation by incorporating a syringe, filtration membrane, vial, and cap/septa all into one product. Each filter vial is comprised of two parts: the external vial and internal plunger with an integrated filter and cap with a pre-slit PTFE/Silicone septa.
