Improved filtration efficiency. Nalgene Rapid Flow disposable filter units with PES (polyethersulfone) membrane feature the exclusive Rapid Flow carrier plate design and offer fast flow rates and high throughput. The optimal protection against cell culture contamination - The PES membranes with low protein binding and low extractables are ideally suited for sterile filtration of cell culture media, sera, additives and buffers.
Features
- The top can be unscrewed from the filtrate bottle for easy access to the filtrate.
- Leak-proof screw cap prevents changes in pH in the filtrate bottle, ensuring longer shelf life of the stored media
- Pore size, membrane type, catalogue number, batch number and expiry date are clearly marked on the upper chamber of the filter units.
- The unpadded membrane support minimises foaming in protein-containing samples.
- Pyrogen-free and non-cytotoxic
- Gamma sterilised and individually packaged for sterile storage for 5 years.
PES membrane (polyethersulfone)- Low protein binding to maintain protein balance
- Low extractable content to maintain media purity
- Blue connector for easy identification
- The asymmetric PES membrane and the unique Rapid-Flow membrane support system enable fast flow rates and a large total throughput for increased filtration efficiency
- 0.2 µm filters remove all bacteria, ideal for sterilisation
- 0.45 µm filters are used for particle removal and liquid clarification
