This product is designed for advanced material research in energy storage, specifically as a separator membrane for zinc battery and other electrochemical systems. The GA-100 glass fiber filters from Advantec provide high porosity, excellent chemical inertness, and thermal stability, which support effective electrolyte retention and uniform ion transport during cycling. Supplied in 110 mm diameter discs with 100 sheets per box, these filters are widely used in laboratory-scale battery assembly and filtration processes. Their consistent microstructure and purity make them suitable for evaluating electrode performance and separator compatibility, enabling reproducible experimental results across various electrolyte formulations.
