NEW!! Sintered filters made of pure quartz glass
As the leading manufacturer of VitraPOR sintered filters, we are expanding our product range with quartz glass filters. From now on you can order standard quartz glass filter discs here. Special designs and intermediate sizes are available on request.
Quartz glass is one of the most demanding of all glasses for use in technical applications. The single-component glass consists of pure, amorphous silicon dioxide (SiO2). Due to its exceptionally high resistance to heat, low thermal expansion and excellent thermal shock resistance, quartz glass is used wherever other glass materials reach their limits.
Slit Sieve Funnel (Buchner Funnel) for membrane- or paperfilter
Our VitraPOR Buchner funnel made of pure borosilicate glass 3.3 with the renown properties like chemical and high temperature change resistance.
A special type of our funnel is equipped with a sieve plate. Contrary to the classical filter funnel with a sintered VitraPOR glass filter disc, it is fitted with a glass disc with approx. 1,8 mm wide slits. This disc is designed for very coarse filtration processes or to support round membranes or paper filters which facilitates to take out the filtrate and to clean the funnel.
The sieve plate is produced by us in a novel manufacturing process allowing special geometries, slit or bore patterns and sizes when required.
See here our available standard sizes.
