Combi syringe filters with a coarse glass fiber prefilter and a small pore membrane as main filter For solutions with a high load of particulate matter: lower back pressure, easy filtration For high yields of filtration: more ml of pure filtrate per filter Glass fiber prefilter to remove larger particles and membrane filters for fine filtration
The glass fiber membrane(1.6㎛) removes coarse particles, before they
can block the fine main membrane. This results in a better filtration
efficiency, especially for highly contaminated samples.
