Glass Fiber Membrane Filters, GS-25, 16mm - 293mm

Advantec GS-25 Glass Fibre Filters – High Wet Strength Prefilters for Analytical and Gravimetric Use

Advantec GS-25 glass fibre filters are fine-porosity prefilters designed for analytical and gravimetric analysis, particularly in workflows where high wet strength and structural integrity are required. With a nominal retention of 0.6 µm and a medium flow rate, these filters are ideal for clarifying liquids ahead of membrane filtration or for general-purpose particulate removal.

Constructed with an organic binder, GS-25 filters offer enhanced mechanical durability under wet conditions, although they are best used with light to moderate particulate loads due to their limited dirt-holding capacity.

Key Features

• Organic binder for improved wet strength

• Fine porosity with 0.6 µm (<0.65 µm) nominal retention

• Medium flow rate: 15 mL/min/cm²

• Suitable as a prefilter for finer membranes

• Thermal resistance up to 120°C

• Thickness: 0.22 mm | Weight: 70 g/m²

Common Applications

• Prefiltration for analytical and gravimetric workflows

• Sample clarification prior to membrane filtration

• General particulate removal in low-load applications

• HEPA-type air filtration
