Culture medium split charging device for test tubes

Abstract

A culture medium split charging device for test tubes comprises a stand column for fixing a sealing container. An air inlet and a liquid outlet are formed in an upper cover and a bottom plate of the container respectively. The stand column is fixed at the center of a base. An annular first groove is formed in the base on the periphery of the stand column. A rotating disc which is driven by a first motor and can carry out quantitative rotating is arranged on the stand column through a sleeve and is placed in the first groove. A coaxialy-arranged tray is arranged on the lower side of the rotating disc. First through holes which are formed in the periphery direction and are used for the test tubes to penetrate through and second through holes which are used for locating the bottoms of the test tubes are formed in the rotating disc and the tray respectively. A pushing rod which can slide vertically is inserted into each second through hole. An eccentric wheel and a second motor for driving are arranged at the lower end of one pushing rod. The culture medium split charging device is a semi-automatic device, split charging efficiency can be effectively improved, split charging accuracy can be improved, and split charging errors are avoided.

Description

technical field [0001] The scheme relates to the field of a tool used in a laboratory, specifically a medium dispensing device for test tubes. Background technique [0002] In the laboratory, "incline" is often used. The so-called "incline" is to fill the medium into the test tube. After autoclaving, the test tube is placed on a certain slope before the medium is solidified to form the "incline" of the medium. , and then the inoculation operation is mainly used to preserve the strains. At present, there is no culture medium dispensing device specially for test tubes in the market. In normal operation, use the rubber tube under the funnel to introduce the melted medium into the funnel, and then introduce the medium into the test tube one by one through the connected rubber tube. When the medium in the funnel is insufficient, replenish it. The disadvantages of this operation method are: low efficiency; easy to contaminate the inner wall of the test tube mouth, and pollute th...
