This heat‑treated quartz binderless glass microfiber filter is pre‑fired using an algorithmically controlled muffle furnace process to ensure consistent and repeatable thermal conditioning. The heat‑treatment produces an annealed filter media that is stronger, more dimensionally stable, and easier to handle during preparation and use. This controlled firing significantly reduces the initial LOI (loss on ignition), improving analytical accuracy in high‑temperature applications. As a result, the filter demonstrates enhanced thermal durability with an effective operating temperature range of ...

Grade 934-AH® - Fine porosity, fast flow rate, with a 1.5µm size particle retention. This material is the standard for volatile suspended solids content and related measurements (Standard Methods 2540D and EPA Method 160.2). Also widely used in cell harvesting applications and RIA scintillation counting. Binderless borosilicate glass microfiber enables use up to 550°C.
