Glass-fibre filters

The glass fibre filters from LABSOLUTE® are made of borosilicate glass without binder and are thus biologically inert. The filters provide a high retention power and simultaneously enable elevated flow rates, which makes them applicable for almost every area of laboratory filtration. Among other things, they are used for clarification of protein solutions, air or water monitoring and for gravimetric and waste water analyses. Furthermore, they can be ideally used as prefilters for membranes.

• Very high resistance to almost all kinds of chemicals
• Temperature-resistant up to 500 °C
• Autoclavable up to 134 °C

• Thickness: 0.26 mm
• Weight: 52 g/m²

Glass microfibre filters have a fast filtration and a high loading capacity and particle retention rate. Manufactured from high grade borosilicate glass. They are suitable for gravity or low suction filtration. Filtration speeds generally very much higher than conventional cellulose papers. Efficient retention of micron size particles. Must be used flat. Ideal for use in flat perforated plate Buchner type funnels (not sintered glass models). Can be used up to 500 °C. Filtration velocity acc. to Herzberg.

Wide range of applications including:

• Retention of fine analytical precipitates
• Retention of biochemical gelatinous precipitates
• Water/air pollution analyses
• As prefilters for membranes
• Scintillation counting
• Radioimmunoassay
