The grade Q3400 is made of 100 % high-purity quartz microfibers only and pre-heated to guarantee excellent weight and dimensional stability. The filters are especially suitable for emissions monitoring at temperatures of up to 900°C and wherever filters of the highest purity are needed. A trace element analysis is performed for each single lot and its certificate of analysis is available on demand.

Quartz microfibre filters are especially suited for emission monitoring at temperatures of up to 900 °C and wherever filters of the highest purity are needed. They are free of glass fibres and binding agents.
