| CHROMAFIL® GF/PVDF |
|
| Polyvinylidene difluoride syringe filters with glass fiber prefilters |
 |
Combi syringe filters with a coarse glass fiber prefilter and a small-pore membrane as main filter |
 |
|
User benefits:
 For solutions with a high load of particulate matter: lower back pressure, easy filtrationFor high yields of filtrate: more mL of pure filtrate per filter
|
|
The technology:
The glass fiber membrane (1.0 µm) removes coarse particles, before they can block the fine main membrane. This results in a better filtration efficiency, especially for highly contaminated samples |

CHROMAFIL® filter membranes |
|
| Chemical compatibility of filter materials |
|
| The following table lists the chemical compatibility of our CHROMAFIL® materials. The chemical compatibility depends on several parameters such as time, pressure, temperature and concentration. In most cases, CHROMAFIL® filters will have only short contact with a solvent. |
|
In these cases they may be used despite of 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. |
