The invention relates to the technical field of molecular biology, and more particularly, to a six-face heating high-temperature sterilization biological shaking table.
A heating high-temperature sterilization biological shaking table is a laboratory equipment used for sterilizing biological materials through high-temperature heating and shaking. This type of sterilization is also known as “dry heat sterilization.” The equipment typically has a heating chamber that is able to reach high temperatures, such as 160-180° C. Inside the chamber, there is a platform or table that can shake or agitate the biological materials, such as petri dishes or test tubes, to ensure that they are exposed to the heat evenly. The high-temperature heating process kills or inactivates microorganisms, bacteria, and other contaminants that may be present in the biological materials, thus making them safe for further experimentation or use. The shaking table helps to ensure that the heat is distributed evenly and that all surfaces of the materials are exposed to the heat for the same amount of time. This type of sterilization is effective for killing microorganisms that are not killed by lower temperatures, such as thermophiles and endospores. It's used in research lab, food industry, medical or pharmaceutical industry and other places where sterilization is required.
In the field of existing biological shaking tables, an interior of a box body of the shaking table is mainly sterilized with ultraviolet rays, or by spraying alcohol or hydrogen peroxide. However, those methods have a disadvantage that corners are not completely sterilized, which affects the final cultivation effects; in addition, the box body has poor thermal insulation performance and is prone to generation of condensed water, it is easy to cause bacterial infection and affect the actual cultivation.
