Thermo Fisher Scientific has announced 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.
