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
