Description

Technical Field

[0001] The utility model relates to the technical field of thermostats, in particular to a clamping structure for test tubes of thermostats. Background Art

[0002] As a device that can directly or indirectly control one or more heat sources and cold sources to maintain a specific temperature, the thermostat is widely used in many fields. Among them, the dry thermostat adopts advanced micro-electric control and semiconductor refrigeration technology, which is particularly suitable for the constant temperature storage of samples of various analytical instruments. In the field of medical injection research and development, the use of the thermostat is particularly critical. It can provide a constant storage temperature for the injection under development, thereby ensuring its stability and effectiveness.

[0003] However, in actual use, some test tube thermostats currently on the market have certain design defects: specifically, these instruments usually do not have a special clamping structure designed for the test tube, which causes the test tube to easily collide with the placement rack during the placement process, thereby causing damage, which not only affects the integrity of the test tube, but may also cause contamination or damage to the sample in the test tube, thereby affecting the accuracy and reliability of the experimental results. Therefore, we propose a clamping structure for thermostat test tubes that is convenient for placing and clamping test tubes to solve the above problems. Utility Model Content
