CHROMAFIL disposable syringe filters GF/PVDF-45/25 membrane material: glass fibre/polyvinylidene difluoride pore dia.: 1.0/0.45 µm, membrane dia.: 25 mm color code above: black / below: white pack of 100

Combi syringe filters are recommended for solutions with a high load of particulate matter or for highly viscous solutions. These products combine a coarse glass fiber prefilter and a small-pore polyvinylidene difluoride membrane as main filter. The hydrophilic PVDF membrane is for 100 % aqueous samples, water-soluble oligomers and polymers like proteins. All CHROMAFIL filters are autoclavable (121 °C and 1.1 bar for 30 min)!
