Frequently Asked Questions
What is a Quartz Frit Filter (Sintered Disc)?
A quartz frit filter, also called a quartz sintered disc, is a high-purity fused quartz component used for fine filtration. It is manufactured by sintering quartz particles together, creating a porous structure that allows liquids or gases to pass through while trapping impurities.
What porosity grades are available in quartz frit filters?
Quartz fritted filters are available in porosity grades 00 to 4, covering pore sizes from 10 microns to 540 microns. This allows selection from coarse separation to ultra-fine particle retention.
What are the standard sizes of quartz frit filters?
Standard diameters range from 10 mm to 100 mm, with thickness options between 2 mm and 5 mm. Custom sizes and shapes can also be manufactured upon request.
How much temperature can a quartz frit filter withstand?
Quartz fritted discs are highly heat-resistant and can operate up to 1100°C in continuous use, making them suitable for high-temperature and thermal shock conditions.
Can quartz frit filters be customized?
Yes. Both diameter and thickness can be customized, and all porosity grades (00–4) can be manufactured to match specific application needs.
What is the difference between quartz frit filters and glass frit filters?
Quartz frit filters are made from fused quartz (SiO₂ 99.99%), which offers much higher purity, thermal resistance, and chemical stability compared to borosilicate glass frits. This makes them more suitable for demanding laboratory, semiconductor, and high-temperature applications.
