System for automatically dispensing medium

Abstract

The invention provides a system for automatically dispensing a medium. The system comprises a cabinet, a driving mechanism is arranged in the cabinet, a vessel sending mechanism, a dispensing mechanism and a liquid injecting mechanism are matched and arranged above the cabinet, and the cabinet is also provided with a control unit for controlling the driving mechanism to operate; a driving mechanism comprises a main motor and an auxiliary motor; the vessel sending mechanism comprises a circular base plate and a dish library rack, the base plate is fixed above the cabinet, the dish library rack is installed on the base plate, and a main motor outputs power to the dish library rack; the dispensing mechanism comprises an upper bracket plate and a lower bracket plate which is under the upper bracket plate, and the central parts of the upper bracket plate and the lower bracket plate are fixedly connected, and the auxiliary motor outputs power to the dispensing mechanism. The liquid injecting mechanism comprises a peristaltic pump and a liquid injecting pipe, the liquid injecting pipe is installed on the peristaltic pump, and one end of the liquid injecting pipe is inserted in a container which is equipped with medium, and the other end of the liquid injecting pipe is positioned between the upper bracket plate and the lower bracket plate. The system reduces manpower cost, improves work efficiency, and substantially reduces risk of medium pollution.

Description

technical field [0001] The invention relates to the technical field of microorganism cultivation equipment, in particular to an automatic subpackaging system for culture medium. Background technique [0002] Plate medium is an indispensable consumable for biological laboratories in many fields such as biomedicine, food and beverage, quality inspection, disease prevention and control, medical treatment, and electronics. High-quality culture medium plays a very important role in the experimental results of the laboratory. At present, the medium plate is mainly artificially packed and poured and purchased finished medium. The amount of poured medium is uneven, the operator has high work intensity, high human capital, low efficiency, and it is easy to contaminate the medium, and the quality of the poured medium is unstable, which affects the experimental results. The cost of finished culture media is high, the shelf life is short (up to 6 months), frequent purchases, and high ...

AI Technical Summary

Problems solved by technology

Manual sub-packaging of the pouring medium plate has uneven pouring medium volume, high work intensity of operators, high human capital, low efficiency, and easy contamination of the medium, and the quality of the pouring medium is unstable, which affects the experimental results

The cost of the finished medium is high, the shelf life is short (up to 6 months), frequent purchases, and high requirements for transportation and storage conditions (2-25°C dark), especially the transportation process requires cold chain transportation, otherwise the quality of the medium will be affected

The existing culture medium dispensing equipment on the market has relatively high requirements for plates. When placing an empty plate and putting a poured plate on top, the plate rack must rotate half a plate position clockwise and counterclockwise. If the plate The top of the cover and the bottom of the dish body have relatively prominent anti-slip edge ribs, which are easy to jam the dish and have a high failure rate, which cannot achieve higher versatility of the plate. The equipment corresponds to a special plate

At present, there are many structures and sizes of plates on the market, but there is no room for choice.
