Description

Technical Field

[0001] The utility model relates to the technical field of constant temperature oscillators, in particular to a constant temperature oscillator sample fixing mechanism. Background Art

[0002] The main body of the constant temperature oscillator includes an oscillation device and a temperature control device. Generally, the temperature control range of the constant temperature oscillator is about 5°C-70°C. Since the oscillation frequency, cavity temperature and time of the constant temperature oscillator are controllable, it is widely used in microbial culture and biochemical cross-linking reactions.

[0003] Existing constant temperature oscillators often use fixed-shape limiting rings to achieve fixation. The fixing process is to insert the sample into the limiting ring and rely on the friction between the two to achieve the limiting effect. However, the sample containers are of different sizes, so different limiting rings are required to achieve fixation. This is inconvenient to use and there is room for improvement.
