อุปกรณ์กรอง CHROMAFIL filtration cartridges
| CHROMAFIL® filtration cartridges |
|
|
Features |
- Filtration cartridges for sample clarification under vacuum (e.g., using the CHROMABOND® vacuum manifold or SPE automation systems like Gilson Aspec™, Rapidtrace) or by gravity
|
|
|
|
-
Different membranes (PET, RC, PTFE, PVDF, GF) and pore sizes (0.2, 0.45 and 1.0 µm). The membrane materials correspond to the respective CHROMAFIL® syringe filters.

|
| 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. |
