|Application|This product can not form stable complex with most metal ions, and can be used as buffer in solution system containing metal ions. It was applied to the purification of tubulin by using cellulose phosphate chromatography. The purified recombinant GTP binding protein ARF1 and ARF2 were purified by gel filtration and used as buffer to crystallize ketoenzyme from E. coli. In addition, PIPES is not suitable for redox system because it can form free radicals. In cation exchange chromatography, a low concentration of PIPES buffer should be used, because pipes has relatively large ionic strength and its pKa value is concentration dependent.

|Product advantage|The purity is >99%, with good water solubility and stable process, which can ensure that the product appearance is pure white crystal powder.

Brief Description: ;
Caustic soda (sodium hydroxide) is a versatile alkali. It is a white solid ionic compound consisting of sodium cations Na+ and hydroxide anions OHâ??. Sodium hydroxide is a highly caustic base and alkali that decomposes proteins at ordinary ambient temperatures and may cause severe chemical burns.

Main Uses/ Industry :
" Caustic soda reacts with bauxite to dissolve aluminium-bearing minerals in the ore so that insoluble impurities can be separated. The purified alumina is then used to produce aluminium.

Caustic soda is commonly used as a reagent in chemical reactions.

Caustic soda is used in the saponification reaction to manufacture soap. In detergents, it is a part of the process of neutralisation of LAB.

Caustic soda solution is used in the exploration, production and processing of petroleum and natural gas. It is also used as an adsorbent for carbon dioxide in light petroleum fractions; a treatment step in removal of various sulphur compounds.

Caustic soda solution is used in the pulping and bleaching process and de-inking of waste paper.

Caustic soda forms an important input in the steel industry. It is used to clean steel.

Caustic soda solution is used to process cotton and dye synthetic fibres such as nylon and polyester. Mercerising of fibre with sodium and hydroxide solution provides greater tensional strength and consistent lustre. It removes waxes and oils from the fibre to make it more receptive to bleaching and dying. In rayon it is used during the viscose process to extract cellulose from pulp.

Caustic soda solution is used in the treatment of water by regenerating the anion resin bed. It is used on a large scale in DM plants."

Guanidine Thiocyanate is a strong chaotropic protein denaturant, and is intended for use in isolation of nucleic acid.Guanidine Thiocyanate is an ultrapure, molecular biology grade reagent. It is free of detectable nuclease and protease activity and is a strong protein denaturant, as both the guanidinium cation and the thiocyanate anion are chaotropic agents. It is provided in one bottle containing 500 g. It is recommended for isolation of RNA, especially for tissues such as pancreas with high levels of RNase activity. In solution, it is known as guanidinium thiocyanate. Guanidine Thiocyanate is thoroughly tested for contaminating nonspecific endonuclease, exonuclease, and RNase activity.

Introduction of polyacrylamide

Polyacrylamide is water-soluble polymer, appearance is white or light yellow toner particles, easy bibulous, long-term thermal decomposition, decomposition temperature above 200 , under anaerobic conditions, 210 carbonized to black powder. Insoluble in most organic solvents, has good flocculation sex, can reduce the friction resistance between liquid, ion characteristics can be divided into non-ionic and anionic, cationic and amphoteric four types.

Polyacrylamide is a kind of abnormal function of the fine water disposal reagents, and is non-toxic, does not pose too much persecution to water quality. Polyacrylamide flocculation treatment of waste water, cover an area of an area small, less investment, strong adaptability, a brief, high processing efficiency, can control the space is large, etc. PH value is too low, acid easily provoked explosion together, constitute a crosslinking shape insolubles, spending anionic polyacrylamide and lower part; With the increase of PH value, weak alkaline acid reaction solution increased, spending amount of polyacrylamide part gradually cut, good ablation.


Polyacrylamide is a kind of efficient additives, is a good assistant, we purify environment polyacrylamide is widely used as flocculant, suspended in liquid has a good job. Many enterprises in order to environmental protection is done using polyacrylamide flocculant, more common is the water purification, textile, coal, paper and other industries. Polyacrylamide is mainly used as pulp fiber and additive of adhesives, polyacrylamide for waste water treatment at the same time. Polyacrylamide has been widely used in water treatment, paper, glue, urban sewage, oil, coal, mining and metallurgy, geology, light textile, construction and other industrial sectors. Especially the flocculation performance application in all walks of life are essential.
