  • SILICA POWDER FOR QUANTITATIVE SUPPLY, PURIFICATION KIT FOR BIOLOGICAL MATERIAL USING SAME, AND METHOD FOR PRODUCING SAME
    Publication number: 20190270066
    Abstract: An object of the present invention is to provide a silica powder having enhanced handleability and quantitative feeding performance, a purification kit for a biomaterial, wherein a plurality of individual compartments of a container are filled with the accurately and quantitatively determined silica powder, and a production method for the kit, and the like. The silica powder for quantitative feeding is a silica powder, wherein 99 mass % or more of particles pass through when the silica powder is sieved through a sieve with a nominal mesh opening of 250 ?m in accordance with JIS standard sieve list (JIS Z8801-1982) for 1 minute, and a mass change on a sieve with a nominal mesh opening of 106 ?m is 1 mass % or less, when the silica powder is sieved through the sieve for 1 minute.
