| Message: | Tris Chinese Name: tris (hydroxymethyl) aminomethane, the appearance of white crystalline powder, good water solubility, can also be dissolved with ethyl acetate, but the dissolution rate is relatively slow, not with ether, carbon tetrachloride, copper, aluminum corrosion. The pKa value of Tris at 25 ℃ is 8, and the buffer range is 7-9. The common Tris buffers are Tris HCl buffer, Tris phosphate buffer and various derivative buffers, such as TBS, Te, etc. Tris is a very important biological buffer, and its CAS number is 77-86-1.
Tris interferes with some pH electrodes, so it is necessary to use the electrode which is compatible with tris solution. In addition, Tris is not suitable for the determination of biquinolinic acid (BCA), and Tris needs to wear gloves and goggles during the operation, because the inhalation, intake and skin absorption of Tris will have a certain impact on the human body.
Desheng biotechnology has been developing and producing biological buffers for many years, and has invested a lot of money in the R & D and production of Tris series products. At present, the company's products have been sold to more than 100 countries around the world, product quality is reliable, price concessions can be discussed, interested can call consultation, Desheng biotechnology welcome your call. |
