2,4,6-Trimethylpyridine N:C(CH3)CH:C(CH3)CH:CCH3 CAS #108-75-8 F.W. 121.18 Bennett & Luft., Biophys & Biochem. Cytol., 6,113 (1959). A very stable buffer, used with Osmium tetroxide; provides excellent fixation, better stability and buffering capacity. The pH can be adjusted by varying the amount of hydrochloric acid in the final volume of 200 ml. Preparation Instructions: Pour 9ml of 2N HCl; add 5.34ml of Sym-Collidine, mix well and add distilled water up to 200 ml for a pH 7.4 solution. Set consists of: – 1 amp 5.34ml Sym Collidine – 1 amp 9.0 ml of 2N HCl Storage : 0-5°C
