LabExact® 934-AH® 1.5um Binderless Glass Microfiber Filter Media, Prewashed, 9cm, 100/PK

Grade A-E - Fine porosity and fast flow rate, with a 1.0µm size particle retention. Binderless borosilicate glass microfiber. DOP efficiency is 99.98%. Primarily used in suspended solids and air monitoring.

Grade 934-AH® - Fine porosity, fast flow rate, with a 1.5µm size particle retention. This material is the standard for volatile suspended solids content and related measurements (Standard Methods 2540D and EPA Method 160.2). Also widely used in cell harvesting applications and RIA scintillation counting. Binderless borosilicate glass microfiber enables use up to 550°C. The trademark 934-AH® is owned by GE Healthcare/Whatman Inc. and used under exclusive license for purposes of private label.

LabExact 934-AH® glass microfiber filters are produced from 100% borosilicate glass microfiber without the use of binders or strengthening agents. Fine porosity, fast flow rate with a 1.5 um size particle retention. This material is the standard for suspended solids content and related measurements (Standard Methods 2540D and EPA Method 160.2). Also widely used in cell harvesting applications and RIA scintillation counting. Binderless borosilicate glass microfiber enables use up to 550°C. Depth filtration traps particulate within the random matrix of fibers within the thickness of ...

Grade D - Coarse porosity, fast flow rate, with a 2.7µm size particle retention. Well suited for higher volume and repetitive laboratory filtering. Also ideally used as a general pre-filter to extend primary filter life. Binderless borosilicate glassmicrofiber.

Grade D filter media features a coarse porosity and fast flow rate, delivering reliable performance with a 2.7 µm particle retention. It is well suited for higher volume, repetitive laboratory filtration where speed and consistency are critical. The robust structure supports efficient throughput while maintaining dependable particulate capture. Commonly used as a general pre-filter, Grade D helps protect and extend the service life of finer primary filters downstream. Manufactured from binderless borosilicate glass microfiber, it offers excellent chemical resistance, low extractables, and ...
