Grade B Glass Microfiber Filter, Binderless Borosilicate, 1.0µm, 70mm, 500°C, 100/Pk SKU: LE-B7000

Featuring binderless borosilicate glass microfiber technology delivering exceptional 1.0µm particle retention with twice the thickness of Grade A and higher loading capacity. Medium to fast flow rate characteristics optimize processing efficiency while maintaining precise filtration performance for biochemical polymer collection and protein precipitation applications. 100% borosilicate glass construction without binders or strengthening agents ensures chemical purity and eliminates contamination interference in sensitive analytical protocols.

Key Glass Microfiber Membrane Characteristics

Combines fine 1.0µm particle retention with exceptional loading capacity for high-volume sample processing
Binderless construction prevents contamination in liquid scintillation counting and sensitive analytical methods
Depth filtration matrix traps particulates within random fiber structure with complex void space efficiency
Thick 675µm borosilicate glass microfiber construction handles samples with high particulate loads
Smooth, uniform fibers enable characteristically high flow rates while retaining exceptionally small particles

Key Construction Characteristics

Temperature resistance up to 500°C enables high-temperature procedures and thermal processing
Ideally suited for collection of biochemical polymers precipitated by denaturation
Functions effectively as solid particulate filter for gases or high-capacity prefilter applications
Biologically inert borosilicate glass resists most solvents and reagents except hydrofluoric acid
Autoclavable construction permits sterilization protocols at 125°C for 15 minutes

LE-B7000 filters achieve fine particle retention combined with good flow rate performance, accelerating your analytical workflows while maintaining superior filtration integrity. Particularly useful for liquid clarification, solids quantification in heavily loaded fine particulate suspensions, and liquid scintillation counting techniques requiring high loading capacity. Standard 70mm diameter accommodates most laboratory filtration equipment configurations, delivering reliable performance for your critical biochemical analysis, protein precipitation, and suspended solids determination applications requiring both chemical purity and thermal stability.
