Tris, technical grade, 1 kg

Specifications

SKU	0210313201
Alternate Names	Trometamol; Tromethamine; Tris-[hydroxymethyl]aminomethane; 2-Amino-2-(hydroxymethyl)-1,3 propanediol;THAM; Tris base
Application Notes	This grade of tris is suitable for use as a standard biological buffer in less critical applications where economy is an important consideration. The pH values of all buffers are temperature and concentration dependent. For Tris buffers, pH increases about 0.03 unit per °C decrease in temperature, and decreases 0.03-0.05 unit per ten-fold dilution. For precise applications, use a carefully calibrated pH meter with a glass/calomel combination electrode.
