GLASS MICROFIBER FILTERS (BINDER FREE)
(Recommended in analysis of air and water according to international standards)
DESCRIPTION
New range of filters made exculsively with 100% borosilicate glass microfiber and free from any type of bonding agent. These filters are capable of combining rapid velocities of filtration with high loading capacities together with excellent retention of fine particles.
PROPERTIES
Chemical stability
This microfibers filters have an excellent stability and base solutions of high concentration.
Thermal stability
Filters can withstand operating temperature up to 500 C.
Permeability
Glass microfibers filters have high permeability.
Retention of particles
These filters have an excellent level of retention of particles.
Load capacity
Due to its high apparent density, these filters have a large load capacity.
