Abstract

The invention relates to an experimental test tube rack with adjustable height. The experimental test tube rack with the adjustable height comprises a supporting seat, a telescopic mechanism and a bearing plate positioned above the supporting seat and parallel to the supporting seat. The telescopic mechanism and an auxiliary telescopic rod are vertically installed between the supporting seat and the bearing plate. The telescopic mechanism and the auxiliary telescopic rod are respectively positioned at the left and right ends of the center position above the supporting seat. The bearing plate is internally provided with a plurality of test tube holes. The bearing plate is provided with a plurality of arc grooves. The lower end of the supporting seat is provided with supporting legs.

Description

technical field [0001] The invention relates to the field of experimental instruments, in particular to a height-adjustable test tube rack for experiments. Background technique [0002] Test tubes are one of the most common glass instruments in the laboratory, and are often used in chemical experiments. The existing test tube racks are usually wooden racks, bamboo racks or aluminum racks, with 6 holes, 12 holes, etc. Usually, the test tube rack is used to place and dry the test tubes. Sometimes the test tube can also be placed on the test tube rack to observe the phenomenon of an experiment. Therefore, the test tube can be said to be the most basic experiment in the chemical laboratory. Instruments, traditional test tube racks are usually equipped with a corresponding number of small wooden columns and small holes for placing test tubes, and some existing devices have gradually appeared test tube racks made of aluminum materials, and the test tubes are realized through a two...
