Nasopharyngeal Swab & Oropharyngeal Swab
Nest nylon flocked swabs provide optimum specimen collection because of their ability to collect more specimen at the collection site and to more rapidly release the entire sample specimen.
ITM (Inactivation Transport Medium)
Features:
1.ITM medium serves to both inactivate viruses and prevent nucleic acid degradation.
VTM (Viral Transport Medium)
Features:
1.Used for collection, storage and transportation of human nasopharyngeal virus samples.
Normal Saline Medium
Features:

Recovery of cerium oxide from spent acid
Scandium oxide is widely used in cutting-edge technology aspects of the nuclear industry, aerospace, rockets, missiles, lasers, electronics and superconductivity, is a rare and precious metals, with the development of high-tech world, demand for scandium oxide will become increasingly increase.
A titanium ore containing iron elements scandium, scandium per tonne of ilmenite containing scandium oxide calculated folded about 0.0065% to 0.018% taken from scandium scandium oxide ore (or the scandium-containing waste) molding process and has alkali Two kinds of acid methods. The alkali method is to treat the antimony ore with alkali, then acidify the crucible into the solution, and then extract and obtain a series of treatments to obtain cerium oxide; the acid method is to pulverize the antimony ore, and then react with sulfuric acid to obtain a solution, and then extract, etc. a series of treatments to obtain cerium oxide
The preparation of cerium oxide from spent acid is mainly because ilmenite contains barium, and ilmenite is decomposed by sulfuric acid, in which titanium, iron, barium, etc. all become soluble sulfates into the solution, and later most of them are removed by freeze crystallization. The iron is then hydrolyzed by heating, and the titanium-forming meta-titanic acid is separated from the solution. The barium sulfate and the like are still left in the solution, and the cerium-containing solution (ie, waste acid) is used for extraction, back extraction, filtration, acid dissolution, The precipitated ruthenium, filtered water washed, re-fired, cooled, and packaged, the finished yttrium oxide product is obtained. The process for preparing cerium oxide from spent acid is shown in the figure below.
