For over 50 years, Andrews Glass has been supplying specialty, precision, and electro-optic glass products to scientists, engineers, and manufacturers in industry, education, and government.
ROBU™porous filter discs, also known as sintered or fritted discs, are high quality filters that can be easily incorporated into your filtration and separation systems. Made exclusively of borosilicate 3.3 glass, through a special milling and sintering process, ROBU filters contain no foreign substances. Because our filters are 100% glass, they can easily be fused to the glass part or filter apparatus for almost any application.
