AI Technical Summary
Existing liquid inoculation devices are prone to causing inoculum to drip outside the bottle when the inoculation bottle is rotated horizontally, resulting in errors in the inoculation amount.
A liquid microbial culture quantitative inoculation device was designed, comprising a limiting component and a supporting component. The limiting component fixes the inoculation bottle mouth through an L-shaped connecting frame and a limiting plate, while the supporting component supports the inoculation bottle through a supporting platform and a spring, ensuring that the liquid outlet is always located inside the bottle mouth and preventing the liquid outlet from deviating during rotation.
This effectively prevents the inoculum from dripping outside the bottle, ensuring the accuracy and uniformity of the inoculation amount.
