Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of microbial experimental apparatus, more particularly to a double mode portable electrode type inoculating loop sterilizer. BACKGROUND

[0002] High-temperature burning of inoculating loops to achieve microbial sterilization is a core step in microbial subculture, isolation and purification. In a complete operation, heating of inoculating loops includes two purposes: complete killing of all microorganisms (sterilization) and partial killing of microorganisms (reduction of biomass).

[0003] Traditional sterilization devices provide a continuous heat source (flame or infrared), and an operator can achieve this by simply changing the heating time, but existing sterilizers that use contact electrodes for heating must be reset at a fixed point. In addition, traditional inoculating loops require the inoculating loop to be held by hand during inactivation in an alcohol lamp or infrared sterilizer, and the operator holds the inoculating loop throughout the process. In the process of repeated operation counted in hundreds of times, not only is it easy to consume the attention and physical strength of the experimental personnel, increasing the probability of making mistakes, but also it wastes unnecessary operation time and reduces work efficiency.

[0004] Therefore, how to propose a convenient and efficient double mode portable electrode type inoculating loop sterilizer is a problem that needs to be solved by those skilled in the art. SUMMARY
