Coal Research Institute of Changsha Hunan Nonferrous Metallurgy Design Institute developed fluidized roasting - acid leaching - ion exchange process has been employed in Hubei Stone Coal smelter (below). Figure Fluidized roasting-acid leaching-ion exchange method for vanadium extraction The main technical and economic indicators obtained by this new process semi-industrial test are: roasting acid leaching conversion rate of 67.03%, acid leaching recovery rate of more than 98%, ion exchange adsorption rate of more than 99%, leaching desorption rate of more than 99%, precipitation of vanadium The recovery rate of ammonium acid is more than 99%, the recovery rate of vanadium from raw material to product is about 65%, the working adsorption capacity of ion exchange resin is up to 420mg/g (wet resin), and the average concentration of eluent V 2 O 5 is about 100g/L. The quality meets the requirements of Class 99 of metallurgy in GB3283-87.
We have a complete plastic consumables production line. Mold-making, injection molding and sterilization, all the procedures are done efficiently in our own factory. Precision molds, high quality raw material and advanced equipment to produce and perform quality testing with strict and comprehensive rules to ensure our products meet the highest quality and performance standards expected by the hospitals, research institutions and industrial, clinical laboratories that we supply.
• Excellent mold-making ability.
Our R&D team, with over 30 years` experiences, work with high quality mold-making equipment imported from Germany and professional mold analysis software that allow NEST to develop more precise molds.
• Injection molding in Class 10,000 and Class 100,000 clean rooms, with strict quality control.
10,764 ft2 Class 10,000 clean room and 32292 ft2 Class 100,000 clean room, all-electric high-speed injection molding machines imported from Japan, raw material which meet USP Class VI requirements. Production and quality control are performed strictly in accordance with corresponding SOP.
• Sterilization by electronic beam irradiation.
The Rhodotron TT200 electron accelerator which imported from the IBA company, Belgium. A world leader in the E-Beam sterilization industry. Sterilization process has been certified by the ISO 11137 quality system. Compared with sterilization by cobalt 60 or ethylene oxide sterilization, sterilization by electronic beam irradiation is more efficient and safer. It requires less time and will not produce any chemical residue.
The length and width of the deep well plate comply with the SBS international standards. The depth of wells is increased based on the appearance and size of normal plates (mainly 96-well and 384-well plates) to enlarge the volume of each well. In addition, the manufacturing material
(currently mostly used is polypropylene (PP)) is changed and the surface treatment process has been improved for this series of deep well plates to adapt to its specific use range. The deep well plates of NEST have a variety of specifications, conforming with the needs of fully automatic workstations and experiments.
When using a thermal cycler with fluorescence detector above the samples, NEST white PCR plates effectively prevent crosstalk between wells. The Nest white PCR plate also allows for high accuracy of detection when signal intensity is low. Nest clear PCR plates are designed for PCR machines where the fluorescence detector is located below the sample plate.
