Advantec GA-55 Glass Fibre Filters – General-Purpose Filters for Air Monitoring and Analytical Use

Advantec GA-55 glass fibre filters are binderless, fine-porosity filters widely used in air pollution monitoring, gravimetric analysis, and general laboratory filtration. With a nominal particle retention of 0.6 µm and fast flow rates, these filters offer reliable performance in applications requiring the capture of fine particulates while maintaining throughput.

Constructed from pure borosilicate glass microfibers, GA-55 filters are free from binders, ensuring high purity, low extractables, and excellent thermal resistance up to 500°C. Their thin profile and fast flow make them a preferred option for environmental air testing and analytical workflows.
