I. Fritted Disc Grade Guide

Note: The following follows the industry-standard classification system. Different manufacturers may have varying pore size standards.

Grade	Pore Size (μm)	Use
G1	80~120	Coarse particle filtration, coarse gas distribution
G2	10~15	Coarse precipitate filtration, gas washing
G3	4.5~9	Fine precipitate filtration, mercury filtration
G4	3~7	Fine particle filtration
G5	1.5~3	Ultrafine particle filtration
G6	<1.5	Bacterial filtration

* Pore sizes may vary by manufacturer.

II. Diameter Options

Diameter	Common Frit Grades	Typical Use
30mm	G2, G3	Low-flow gas or liquid filtration
65mm	G2, G3	Routine flow filtration
80mm	G2, G3	Medium-flow filtration

Description

The fritted filter ball is a spherical glass fritted filter that can be connected with barbed fittings, suitable for pressure or vacuum filtration of gases and liquids in the electronics and pharmaceutical industries. Made from high-quality borosilicate glass 3.3, it offers excellent physical and chemical properties with uniform pore size distribution.

The key design of the fritted filter ball features a spherical chamber combined with a sintered fritted disc: gas or liquid enters from one end, passes through the sintered frit inside the ball, and exits from the other end. Fritted disc grades cover the G1~G6 full range, with diameters from 30mm to 180mm — meeting diverse flow rate and filtration precision requirements.

✦ Key Advantages: Compared to conventional filtration devices, the spherical design offers low flow resistance and large filtration area. Firm welding overcomes the fragility of traditional glass filters. Uniform pore size distribution ensures consistent and reliable filtration results. Barbed fitting compatibility allows for easy installation.

Quality Assurance

Every fritted filter ball undergoes rigorous pore size inspection, visual inspection, and material testing to ensure the frit is intact, unclogged, and has uniform pore size. Bulk orders support custom diameters and fritted disc grades — welcome to inquire.

Tip: Inspect the fritted disc for cracks or clogging before use. Clean immediately after use to prevent residue from blocking the frit pores.
