Constant-temperature oscillator for biochar experimental research

The utility model relates to the technical field of constant-temperature oscillators, discloses a constant-temperature oscillator for biochar experimental research, and aims to solve the problems that a test tube filled with a reagent is easy to collide with an oscillation chassis in an oscillation process to cause breakage of the test tube, and the existing constant-temperature oscillator is large in oscillation amplitude, low in oscillation efficiency and high in oscillation efficiency. The constant-temperature oscillator comprises a constant-temperature oscillator body, a heat preservation cover plate is installed on the upper surface of the constant-temperature oscillator body, a base plate is installed in the constant-temperature oscillator body, placing openings are formed in the upper surface of the base plate at equal intervals, and fixing devices are installed in the placing openings. Due to the fact that the passive clamping block and the active clamping block are both made of silica gel, the test t
