Glass Fiber Syringe Filters

Glass Fiber Syringe Filters

Hydrophobic material. Excellent compatibility with organic solvents and strong acids ( apart from hydrofluoric acid) and bases. Syringe Filters contain a glass fiber filter with a retention efficiency of 98% for 1.2 μm spherical particles. It is very useful when relatively dirty solutions have to be clarified, or as a pre-filter.



Ultrasonic welding ensures no contaminant to samples
Luer lock inlet provides strong,leak-tight syringe connection to withstand filtration pressure.


Hydrophobic membrane
High flow rate
100% Borosilicate glass
Luer lock inlet Tip make sure secure connection and avoid filter blow off


Filtration of aqueous and organic solutions
Pre-filter of small volume liquids to avoid saturation of small-porosity membranes
Fuel hydraulic fluids and machined parts
Increased sample throughput
Large particulate removal
Pre-filtering of suspensions

Chemical Compatibility

Incompatible with :
Limited resistance with ammonia, NaOH and KOH solutions
Benzyl alcohol
