◆ Finetech®-Glass Microfiber Filter
Micro-glass fiber filters offer high efficiency, submicron particle retention combined with high permeability and high dust holding capacity . Micro-glass filters are made of high-purity borosilicate glass microfibers that are biologically inert and resistant to most solvents and reagents with the exception of hydrofluoric acid and highly concentrated alkali solutions.
Binder-free grades are temperature resistant to about 500℃.Grade MG 550 HA can withstand temperatures to 550℃. Grades with binders can resist temperatures of about 180℃ and brief exposures to 250℃.

Glass fiber filter - MGF
◆ Glass fiber filter - MGF This glass fiber filter has a very rapid flow rate and an extremely high loading capacity. Because of the tight specification of 0.7 µm particle retention and pure borosilicate glass structure, MGF is the material upon which the EPA Method TCLP 1311 for Toxicity Characteristic Leaching Procedure was developed. It remains today the filter of choice. Recommended for DNA binding and purification. Very effective in filtering finely precipitated proteins,MGF can be used in conjunction with MGD as a prefilter for the successful clarification of extremely difficult biochemical solutions and fluids, and nucleic acids. ◆ Micro-Glass Fibers without Binder Grade Basis Weight (g/m2) Thickness (mm) Particle Retention in Liquids (μm) Pressure Drop* (mbar) MGF 75 0.45 0.7 120 *A = 10 cm2, flow velocity 400 cm3/sec Grade Application MGF Higher efficiency in particle retention for smaller particles than other glass fiber grades, clarification of protein solutions, filtration of liquids prior to HPLC ◆ Cross reference: Finetech Whatman E-D Scientific Specialities Advantec MGF GFF 151 GD-75
