PURPOSE: An auxiliary tool for chemical experiments is provided to allow a user to safely perform a heating experiment by using a test tube or flask after installing a clamp holder or using a beaker or other containers after installing a heating object support. CONSTITUTION: In the auxiliary tool for chemical experiments, three coupling holes(12a,12b,12c) are formed in line on the top surface of a base plate(10) to allow a support(14) to be fitted into one of the holes, in which the support is provided with female and male screws on the both distal ends and a plurality of recesses(15) along the circumference thereof at regular distances. A clamp holder(20) having nippers(21) and a horizontal bar(22) is installed to the support with a holder fastener(30) in a rotatable and length adjustable manner. A heating object support(40) having ring shaped support members(41a,41b) to be installed to the both ends of the horizontal bar is installed to the support with a fastener(50).
