Inoculation instrument for culture and reproduction of microbial bacteria

Abstract

The invention belongs to the technical field of microbial inoculation, and particularly relates to an inoculator for microbial bacterial culture and reproduction, which comprises a controller, a base and an inoculation ring. The top of the base is rotationally connected with a rotary disc, a motor is fixedly connected inside the base, and an output shaft of the motor is fixedly connected with the rotary disc. An iron powder tray is fixedly connected to the top of the rotary disc, and a magnetic strip is slidably connected to one side of the iron powder tray. A magnet is fixedly connected to the interior of the inoculation ring, and a heat insulation plate wraps the magnet. In the prior art, the inoculation effect is poor or the inoculation fails due to the fact that the scribing track is not obvious and continuous scribing or separated scribing can be hardly carried out according to the scribing requirement for some personnel with unskilled scribing skills. In the invention, iron powder in the iron powder tray is adsorbed by the magnet in the inoculation ring, the iron powder is adsorbed on the top of the iron powder tray due to electrostatic force, and an inoculation track is displayed, so that the scribing track is clear and convenient for personnel to observe, thereby facilitating scribing and further improving the inoculation effect.

Description

technical field [0001] The invention belongs to the technical field of microorganism inoculation, in particular to an inoculation instrument for cultivating and multiplying microorganisms and bacteria. Background technique [0002] When using a medium plate to isolate and culture bacteria, it is often necessary to streak the medium plate. The purpose of streaking is to dilute the mixed microorganisms or different cells or bacteria in the same microbial group on the surface of the plate culture medium to obtain more independently distributed single cells or bacteria, which grow and multiply into A single colony is usually regarded as a pure species of the microorganism to be isolated. [0003] For example, a Chinese patent with an application number of CN201510417939.2 discloses a microbial streaking and inoculating instrument, including a housing, a frequency converter, a motor, and a controller located inside the housing, and a control panel and sensors located on the hous...
