Commonly used in chromatography columns, this fine filtering fiber is made of Pyrex borosilicate glass. It keeps the solid phase of standard gravity liquid chromatography columns in place, and is commonly used in purification of organic compounds. Borosilicate Pyrex is non-reactive with most solvents and organic compounds and has a lower thermal coefficient of expansion.
