Precision Filtration Media

The LABEXACT 12K995 is a binderless borosilicate glass microfiber filter designed for laboratory air and liquid analysis. Its 1.5 um pore size captures fine particulates while maintaining flow. Each pack contains 100 discs sized at 9 cm diameter for high-volume testing workflows.

Replaces Basic Cellulose Pads

Standard paper filters often shed fibres or degrade above modest temperatures. This grade withstands 500 Degrees C, so it survives ashing and hot gravimetric procedures that destroy cellulose. The jump is worth it whenever thermal stability or low extractables are required by the method.

Handles 100-Sample Batches

A single pack supports 100 filtration runs, giving ample headroom for routine environmental or quality-control series. The 0.43 mm thickness provides mechanical strength for vacuum or pressure setups. It is not suited for sub-micron sterile filtration or applications demanding rated membrane pore integrity.

Questions about this item

What diameter funnel or holder fits the 9 cm glass microfiber filter?

The filter measures 9 cm in diameter, so it fits standard 9 cm filter funnels, vacuum manifolds or Gooch crucibles that accept a 9 cm disc.

How do you install the binderless borosilicate glass microfiber filter without tearing it?

Wet the filter with a few millilitres of the sample liquid or distilled water before applying vacuum; the moisture eliminates air pockets and prevents the brittle 0.43 mm media from cracking under differential pressure.

When should the 1.5 µm pore-size filters be replaced during gravimetric analysis?

Replace a filter when its mass change between successive weighings exceeds your method’s acceptance criterion or when visible loading reduces flow rate below the required filtration speed.
