ROBU VitraPOR glass filters made of high-purity quartz glass are designed for use in the most demanding thermal and chemical environments. Offering exceptional resistance to thermal shock and aggressive substances, these filters are ideal for applications requiring the highest level of temperature and material stability. With a maximum operating temperature of up to 1100 °C, they are perfectly suited for high-temperature processes, trace analysis, and cleanroom-compatible procedures. Available in various defined porosities, VitraPOR quartz filters ensure precise and reproducible filtration performance where standard borosilicate filters reach their limits.

In compliance with ISO 4796-80 and ASTM E128-99 standards.
