CHROMAFIL® Syringe Filters – Polyvinylidene (PVDF)
- Hydrophilic membrane
- For polar and nonpolar solutions, water-soluble oligomers and polymers like proteins
- Binding capacity for proteins 82 µg/filter
- The PVDF filter with integrated glass fibre prefilter (GF/P) is recommended for filtration of biological samples with high particle loads. This filter features a high binding capacity for proteins.
- Also suited for filtration of polar and non polar solutions
- Features stability and hydrophobic interactions similar to PTFE

CHROMAFIL Disposable Filters
This table lists the chemical compatibility of our CHROMAFIL materials. The chemical compatibility depends on several parameters such as time, pressure and concentration. In most cases, CHROMAFIL filters will have only short contact with a solvent. In these cases they may be used despite limited compatibility. For example, a PTFE filter with PP housing does not liberate any UV-detectable substances during filtration of 5 ml THF, although PP shows only limited resistance towards THF.
