Thermo Fisher Scientific Introduces New Rapid-Flow Filter for Faster Results

Innovative Design Uniformly Supports Filter Membrane to Enable Faster Filtration of Cell-Culture Media

MILFORD, Mass. (April 17, 2012) – Thermo Fisher Scientific Inc., the world leader in serving science, today announced the availability of the new Thermo Scientific Nalgene Rapid-Flow Filter, which enables faster filtration of cell-culture media. All Thermo Scientific Nalgene filter units and bottle-top filters will now incorporate the Nalgene Rapid-Flow™ membrane support system.

The Nalgene Rapid-Flow design maintains membrane stability, providing better performance and increased flow rates for faster throughput of media.

Most filters use a radial spoke design to support the filter membrane. The wide space between the spokes allows the membrane to be displaced during filtration, which can stress the membrane and distort its pore structure. The result is suboptimal flow rate and throughput. In contrast, the Nalgene Rapid-Flow uses an array of evenly spaced columns that are close enough together to provide uniform support of the membrane, yet far enough apart to allow rapid filtration, resulting in improved flow rate and throughput.

“We are very excited to share this new technology with our customers,” said Dennis Gorlick, senior product manager, lab ware and specialty plastics, Thermo Fisher. “With this advancement, we are providing a product that increases filtration flow rate and throughput while providing a last line of defense against contamination, especially for cell-culture applications. The Rapid-Flow Filter will help our customers save valuable time in the lab.”
