Compound Paper Bag with 25kg/bag or Cardboard Bucket. Reagent-grade products are packaged with 250g plastic bottle (or be packed according to the measurement requirements of customer and OEM Package as well).
The product is a light yellow or yellow-brown powder with no caking. It has an endemic taste and odor, with no other peculiar smells, and contains no visible extraneous impurities.
Yes. While we provide general specifications for industrial, pharmaceutical, and reagent grades, we can fully customize the physicochemical indexes according to specific customer requirements.
The industrial grade is slightly soluble in a 2% solution, whereas the pharmaceutical grade and reagent grade are completely pellucid (clear) when dissolved.
The product must be fully dissolved and properly sterilized before it is put into use.
We offer 25kg/bag compound paper bags or cardboard buckets. Reagent-grade products are packaged in 250g plastic bottles. Custom measurement packaging and OEM packages are also available upon request.
Across all grades (industrial, pharmaceutical, and reagent), the standard specifications restrict the ash content (on dry matter) to ≤10.0% and the moisture levels to ≤6.0%.
