Tromethamine (Tris) - Excipient

BIO EXCIPIENT GRADE | TR3220 | CAS# 77-86-1

INTENDED FOR USE AS AN EXCIPIENT

Product-image

Tris, commonly used as a buffer in biochemistry and molecular biology,
stabilizes the pH of solutions in electrophoresis and other biological
applications. It is also an enzyme inhibitor used in the biopharmaceutical
industry and is commonly utilized in electrochromatography, UV
analysis and HPLC applications. Tris is extensively used as a
biological buffer or a component of buffer solutions. Tris can be
used as a “Good’s” buffer because it has low UV absorptivity,
minimal reactivity, stable pH and is soluble in water.


These are general specifications. BioSpectra will customize our products to meet your quality based requirements.
