| CHROMAFIL® GF/PET | |
| Polyester syringe filters with glass fiber prefilters |
Features
 |
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 filtration For 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 |
||
| Housing: | Solvent-resistant, ultra low bleed polypropylene | ||
| Entry: | Luer lock | ||
| Exit: | Luer | ||
| Pore diameter: | 1.0 / 0.20 µm or 1.0 / 0.45 µm | ||
| Filter diameter: | 25 mm | ||
| Void volume: | < 80 µL | ||
| Packing unit: | 100 filters / BIG-BOX with 400 filters | ||
|
Hydrophilic multipurpose membrane |
|
For polar and nonpolar solutions the HPLC filter with glass fiber prefilter, especially suited for eluent mixtures of water and organic solvents |
|
Recommended for solutions with a high load of particulate matter or for highly viscous solutions |

| 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. |
