Description
Quartz microfibre filter grade Q3400 is produced entirely from 100 % high-purity quartz microfibres and is heat-pretreated to guarantee excellent weight constancy and dimensional stability throughout use. The filters are especially suitable for emission control at temperatures up to 900 °C and for applications in which the highest purity demands are placed on the filter medium itself. A dedicated trace-element analysis is performed for every production batch and is documented with a certificate of analysis, supporting reliable analytical and environmental monitoring workflows. Grade Q3400 from manufacturer Sartorius is selected when low blank contribution, high thermal resistance and stable filter geometry are essential for gravimetric sampling and related laboratory procedures. Outstanding dimensional stability after heat pretreatment helps maintain consistent filtration behaviour under demanding thermal conditions. These quartz microfibre filters serve professional laboratory and emissions-testing environments that require reproducible results at elevated temperature. They are supplied in a practical pack of 50 pieces for routine monitoring and quality-control programmes.
This article is part of Glass & quartz fibre filters, in Filtration.

Questions about Quartz microfiber filters Q3400
What is this article?
Quartz microfiber filters Q3400 is the article on this page. Luminix Health distributes Sartorius for laboratory use. It sits in Glass & quartz fibre filters, inside Filtration, in Lab consumables.
Glass-fibre and quartz-fibre filters are depth filters with a high dirt load, used for air sampling, for total suspended solids and in front of a membrane. They have no sharp pore-size cutoff the way a membrane does. Binderless grades matter when the filter will be weighed or heated.
Filtration holds back what is larger than the pores and lets the rest through. Paper is the ordinary laboratory filter. A membrane has a stated pore size and a polymer that must survive the solvent. A syringe filter is that membrane in a housing on a syringe. Glass fibre takes a higher dirt load. Ultrafiltration holds back macromolecules and passes salts. The pore size, the chemical compatibility and the volume are the three choices. Laboratory apparatus around filtration is indexed under ISO laboratory apparatus.
