New Syringe Filter Speeds Sample Preparation

Mar 24 2010

Millipore Corporation announced the introduction of the redesigned Millex® 13mm sample preparation syringe filter. The filter, which is used in tens of thousands of laboratories worldwide to prepare samples for critical techniques, including HPLC, UHPLC, and LC-MS, has been redesigned to provide greater speed and recovery than conventional syringe filters of the same size. Increasing filtration speed also increases pressure on the filter housing. The new 13mm filter utilises a novel, Milliporepatented housing design that withstands higher operating pressures than conventional 13mm filters (up to 150 psig), and, therefore, allows for faster filtration.

In addition, the new device is low in extractables that can be detected by sensitive analytical instruments. It also has 50% less sample hold-up volume, so more sample is recovered after filtration.

“Device manufacturing cleanliness is especially important given the increasing sensitivity of today’s analytical instruments,” said Rebecca Duguid, Analytical Sample Preparation Product Manager. “The new 13mm Millex syringe filter is manufactured in a clean room to pharmaceutical standards with fully automated equipment and 100% visual and physical inspection.”

The new 13mm Millex syringe filter can be used to prepare from 1 to 10mL of sample. It is available in two pore sizes and four membrane materials: polyethersulfone (PES), polytetrafluoroethylene (PTFE), nylon, and
polyvinylidene fluoride (PVDF). The housing is color-coded by membrane type for easy identification. The device is compatible with a wide range of solvents and other chemicals, which makes it well suited for all analytical applications and sample types.
