A new- type burette holder was designed for analytical chemistry experiments and testing laboratories of enterprises and institutions. An instrument for repairing the damaged burettes was also invented. In addition, the unclear scale lines of burettes can be easy to read by the new method. Thus, the teaching cost was saved and the students would fell easy in a titration experiment.
