LabExact® Grade A 1.6um Binderless Glass Microfiber Filter Media, 2.1cm, 100/PK

Grade TCLP - Binderless borosilicate glass microfiber filter media with a particle retention of 0.7µm. Acid treated and multi-stage deionized water rinsed to conform to EPA Method 1311. Inherently low Barium and Zinc Borosilicate Glass and resistant to acids and bases. Recommended for use in U.S. EPA Method 1311 "Toxicity Characteristic Leaching Procedure". Method scope: "The TCLP is designed to determine the mobility of both organic and inorganic analytes present in liquid, solid and multiphasic wastes." Saves time and waste disposal expense in the lab by eliminating technician acid ...

Grade D Coarse porosity, fast flow rate, with a 2.7um 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. Glass microfiber filters are produced from 100% borosilicate glass microfiber without the use of binders or strengthening agents. Depth filtration categorizes filter media that traps particulate within the random matrix of fibers found within the thickness of the media. The efficiency rating of the filter is characteristic of the complex void space structure that develops ...

Binder free glass microfiber used for Determination of Total Suspended Solids (Standard Method 2540 D. and EPA Method 160.2) and Volatile Suspended Solids. Features: 934-AH® Pre-washed and weighed for high heat applications >550° Washed, dried, desiccated and fired to 550°C Weighed to 4 decimal place resolution Industry standard 934-AH® glass microfiber filter, ready to use Meets requirements for use with VSS and TSS analysis Compares to Whatman RTU series, Environmental Express Pro Weigh series, Ahlstrom Munksjo 169W series

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.

Grade A Fine porosity, fast flow rate, with a 1.6µm size particle retention. Frequently used in the filtration of precipitated proteins and cells. Ideally suited for use as a filter for radioimmuno assay of weak beta emitters by scintillation counting and gravimetric determination of airborne particulate. Glass microfiber filters are produced from 100% borosilicate glass microfiber without the use of binders or strengthening agents. Depth filtration categorizes filter media that traps particulate within the random matrix of fibers found within the thickness of the media. The ...
