MultiDensity 1000 Glass Microfiber Filter, Binderless
The MultiDensity™ product platform now includes this easy to use, thinner1 binderless glass microfiber filter which retains solids in a broad size range. Larger solids become entrapped on the built in pre-filter layer allowing the multiple density zones of filter to entrap finer solids rapidly and reliably. This yields a faster flow rate with higher fluidic capacity.
The borosilicate glass is highly resistive to aggressive solvents, acids (not compatible with hydrofluoric acid) and base with a usable range of 0-14pH and a wide effective temperature range of -200 to 500°C. However, it may become brittle and susceptible to cracking at < -100°C.
Up to 4x capacity of traditional glass microfiber filters in same porosity range
- Handles larger sample volumes or samples with higher ratio of solids.
- Less frequent filter changes = fewer variables in sample prep.
- 100% binderless glass microfiber, formed to create a built-in pre-filter
- Lower extractables for better quality analysis.
- Wide ranging chemical compatibility borosilicate glass.
Finely controlled porosity for consistent and reproducible results
- Extends the life of a membrane when used in series.
- Disk to disk results are consistent.
Laser cut for decreased fiber shedding and increased handling stability
- Fibers on cutline are fused together to form an easy to handle disk.
- Fewer extraneous fibers to wash out into filtrate.
