Print PagePack of 100 30mm PVDF 0.45um syringe filters with a glass fiber prefilter
30mm Uniflo syringe filters containing a glass fiber prefilter to get reliable and consistent test results for labs that routinely prepare analytical sample with maxium value. This will reduce the number of devices needed for sample process and decreases plastic waste.
Prefilters enable you to obtain more filtrate from difficult samples that would clog single layer syringe filters
Features:
- Multi-layer construction reduces the number of filters needed to complete sample preparation (compared to a filter without a prefilter)
- Filter reduces hand strain when compared to filters without a prefilter, while maximising throughput
- Suitable for low protein binding applications, applications utilising both aqueous and organic buffers - including labs in environmental and academia
- 30mm polypropylene housing
- 0.2 and 0.45um pore sizes
- Nylon, PVDF, PES, PTFE and H-PTFE membrane choices
- Tested chemical resistance with many common solvents
- Each manufactured lot is integrity bubble point tested
- 100 and 500 pack sizes

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. |
