1.0 M BIS-TRIS propane

100 mL bottle of 1.0 M BIS-TRIS propane Optimize Reagent.
Citrate BIS-TRIS propane (CBTP) is a buffer system useful across pH 2.5 to 9.5.
Using CBTP one can use a single buffer system to screen pH 2.5 to 9.5 by varying the ratio of Citric acid to BIS-TRIS propane. Although the two buffer reagents are made available separately for convenient, individual replacement, they are designed to be used together, with the supplied CBTP buffer titration table to create a crystallization buffer system covering pH 2.5 to 9.5.
