77-86-1 factory Offer Tris (hydroxymethyl) aminomethane 

Tris (hydroxymethyl) aminomethane is widely used in acute metabolic and respiratory acidemia, and is an alkaline buffer that has a good buffer effect on metabolic acidosis and enzyme activity response. Tris is commonly used as a biobuffer with a pH of 6.8, 7.4, 8.0, 8.8. Its structure, pH varies greatly with temperature. In general, the PH value decreases by 0.03 for each one degree increase in temperature. Tris is widely used in the preparation of buffers in biochemistry and molecular biology experiments. For example, Tris are required for TAE and TBE buffers commonly used in biochemical experiments (for the dissolution of nucleic acids). Because it contains amino acids, it can condense with aldehydes. Tris is a weak alkali with a pKa of 8.1 at room temperature (25 degrees C), and according to the buffer theory, the effective buffer range of Tris buffer is between pH7.0 and 9.2. Tris alkali aqueous solution pH at about 10.5, generally add hydrochloric acid to adjust the pH to the desired value, you can obtain the pH buffer. However, attention should also be paid to the effect of temperature on the pKa of Tris.

77-86-1 for sale Tris buffer Tris (hydroxymethyl) aminomethane Good Supplier In China

Tris buffer solution is not easy to store for a long time, low concentration of reserve liquid, the number of uses is also small, generally ready-to-use. CN201510468240.9 provides an open-to-use, easy-to-store, preparation method simple and fast preparation method of trihydroxymethyl methane buffer tablet preparation method. Here are the steps:

(1) Trihydroxymethylmethane methane, boric acid, EDTA, crosslinked straight chain starch, according to the weight ratio of 54:22:3.0:3.3 in order of accurate weighing. For example, trihydroxymethylmethane methane 540g, boric acid 220g, EDTA30g crosslinked straight-chain starch 33g, mixed well;

(2) pressed into tablets on the tablet press, pressing pressure of 2-4 tons, pressing 200 tablets, containing trihydroxymethylmethane methane, boric acid, EDTA, cross-linked straight chain starch, its weight ratio is 54:22:3.0:3.3;

(3) When used, a piece of water dissolved in 500 ml distillation, that is, PH8.0 buffer solution.
