อุปกรณ์กรอง Syringe Filter CHROMAFIL RC

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 membrane
For aqueous and organic – aqueous liquids, i.e. for polar and medium polar solutions
Recommended for solutions with a high load of particulate matter or for highly viscous aqueous 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.
