Quartz Microfiber Filters / Grade Q3400

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.
