(Trometamol, Tromethamine, Tris-[hydroxymethyl]aminomethane) Purity: 99.0-99.5%
Buffering
pH range 7.0-9.0
pKa at 25°C = 8.1
This grade of tris is excellent where purity and value are both important. It is superior to our technical grade tris and less expensive than our ultra pure material. This grade will suffice for most buffer applications.
