Because of their strong, fibrous, and non-clogging nature, glass fiber filters make excellent prefilters for a wide variety of filtration workflows from basic liquid filtration to highly specialized gas and air filtration. These same properties make glass fiber filters excellent as direct filters too for the clarification of buffers, reagent and protein solutions, as well as gravimetric, air monitoring and wastewater analysis. Their 100 % borosilicate constructions give glass fiber filters a highly pure, extremely white appearance and is the reason that these filters continue to perform over long periods without a loss in performance compared to standard cellulose filters, for instance which demonstrate a decline in filtration performance as filtering load increases.
Quartz fiber filters are made of a specialized crystalline quartz microfiber material and represent the pinnacle quartz technology. Sartorius’ quartz filters are 100% quartz crystal without any addition of glass microfibers or binding agents making them very resistant to heat and highly pure. In addition, the quartz filters, grade Q3400 are tempered to remove all chemically combined water and to give the filters excellent weight and dimensional stability. These highly specialized filters are especially suitable for demanding situations where only the highest purity, yet great durability and retention are required such as in emissions monitoring at temperatures of up to 900° or other high temperature, highly corrosive situations.
Thus for smooth fast filtering in tough situations, hot, cold, wet or dry, always choose Sartorius glass or quartz microfiber filters
