Hawach BIO-42 2.5 micron filter paper is equivalent to Whatman’s filter paper Grade 42 with a more competitive price, which has a high retention rate and a slow flow rate (2.5μm). The finest particle retention in all Hawach laboratory filter paper. Commonly used for the determination of the elemental content of minerals such as barium sulfate, metastannic acid, calcium carbonate, barium carbonate, filtration of gasoline or organic solvents, and filtration preparation of spectral and chromatographic samples, such as atomic absorption (AAS) determination of the second laurel in the feed.
Laboratory filter paper is a medium-speed filter paper that retains fine particles in cellulose filter paper. Commonly used for the analysis of fine particle sediments such as barium sulfate, metastannic acid, and calcium carbonate. Filter paper used in the laboratory can use the determination of the content of dibutyltin acid. Similarly, cellulose filter paper grade 44 is also possible.
Features of Quantitative Laboratory Filter Paper Grade 42
1. Laboratory filter paper is ideal in repetitive or multiple analyses. 2. Supplied in sheets, discs, as well as folded formats 3. High-purity filters contain 0.0009% maximum ash content 4. Particularly useful for gravimetric analysis 5. Slow filtration speed and the nominal particle retention rating of 2.5μm 6. 2.5 micron filter paper is equivalent to Whatman’s filter paper Grade 42
Advantages of Filter Paper Used In Laboratory Grade 42
1. Filter paper used in laboratory is acid-washed and has an extremely low ash content 2. FDA-grade manufacturing capabilities. 3. High quality with cost-effective 4. Full range of diameter and OEM service available
Applications of 2.5 Micron Filter Paper BIO-42
1. Precipitates of the specific gravity analysis 2. Barium sulfate, stannic acid, and fine precipitated calcium carbonate, and other 3. Widely used in methods to prepare samples for further testing using many types of instrumentation.
