Nuclepore track-etched polycarbonate membranes are manufactured from high-quality polycarbonate film and have sharply defined pore sizes, high flow rates and excellent chemical and thermal resistance. The membranes have a smooth flat surface and exhibit very low levels of extractables.
Features and Benefits
- Low protein binding and low extractables ensuring no sample contamination
- High chemical resistance and good thermal stability for a wide range of samples
- Low, consistent ash and tare weights
- Smooth flat surface for good visibility of particles
Applications
- Epifluorescence microscopy
- Environmental analysis
- Cell biology
- EPA testing
- Fuel testing
- Bioassays
- Parasitology
- Air analysis
- Water microbiology
Guide to…Membrane Filter Properties
Identifying the filter material most suitable for your application based upon the nature of the liquid or gas you are filtering will ensure the best performance of your filter. Each membrane filter material has differing chemical and physical properties such as hydrophobicity, flow rate, extractables and protein retention making them suited to differing applications. Once you have selected the most compatible filter material, you will need to consider what pore size is most appropriate.
| Membrane Material | Protein binding | Hydrophilic/Hydrophobic | Chemical resistance | Applications |
| Hydrophilic PTFE | Low | Hydrophilic | High | Purification of HPLC organic and solvent/aqueous solutions |
| Hydrophobic PTFE | Low | Hydrophobic | High | Filtration of solvents |
| PES | Low | Hydrophilic | Low/Medium | Purification of tissue culture solutions, buffers |
| PVDF | Low | Hydrophilic | Medium | Filtration of protein solutions |
| NYL | Medium | Hydrophilic | Medium | Filtration of aqueous and solvent/aqueous mixtures |
| CA | Low | Hydrophilic | Low | Filtration of protein solutions |
| CN | High | Hydrophilic | Low | Filtration of aqueous solutions where protein binding is not a concern and microbioloigical applications. |
| RC | Low | Hydrophilic | Medium | Filtration of aqueous and organic solvents and protein recovery applications. |
