BioGrade® Trifluoroacetic acid (TFA)
BioGrade® TFA is an ultra high purity grade of trifluoroacetic acid designed for use in purity-critical fields such as peptide or protein research and in applications where very low levels of impurities and nonvolatile residue are desired. It can be used directly from the bottle without any further purification.
