Glass Microfibre Filters – BM/D / Equivalent Whatman Grade GF/D
Nominal Pore Size: 2.7µm. Diameter: 110mm. 100 Discs.
Glass Microfibre filters are manufactured from 100% borosilicate glass: binder-free and chemically inert. The fine fibres of glass microfibre filters allow high efficiency rates even down to the sub-micronic range combined with good permeability and high dirt holding capacity. The fine capillary structure can absorb significantly larger quantities of water than an equivalent cellulose filter, making them suitable for spot tests and liquid scintillation counting methods.
Specifications / Applications
Glass microfibre filters can be used at temperatures up to 500°C.
They are ideal for use in applications involving air filtration and for gravimetric analysis of volatile materials where ignition is involved.
The filters can also be made completely transparent for subsequent microscopic examination.
Binder free, eliminating possible sample contamination due to no added extractables.
With particle retention in liquids from 0.7µm to 2.7µm
High retention for filtering particles in the sub micron range
Ideal for use in the food and beverage industry, biochemical protocols and environmental analysis.
They are non-gyroscopic and biologically inert.
Chemical resistance to most solvents and reagents is very good, except for hydrofluoric acid and other acids or alkalis at high concentration.
