Embodiment 1

[0040] This example provides a process for the laboratory to automatically configure LB culture medium. LB medium is one of the most commonly used media in microbiology laboratories. In this example, the experimenter needs to configure LB medium. According to the "Molecular Cloning Experiment Guide", 1L liquid LB medium should be added to 950ml deionized water: 10g tryptone, 5g yeast extract, 10g NaCl, adjust pH to 7.0 with 5mol / L NaOH, and dilute to 10g with deionized water. 1L.

[0041] When using the present invention to prepare the LB medium, the experimenter turns on the machine, such as figure 1 As shown, click Start in the 2-Control panel, then select common medium, and then select LB medium, the panel will display: Please put tryptone in No. 1 feeding port, and put yeast extract in No. 2 feeding port, No. 3 feeding port is put into NaCl. Experimenters add each raw material as required, and the quality of the added raw material must exceed the required amount. The ...

Embodiment 2

[0047] This example provides the process of automatically configuring the phenylalanine medium in the laboratory. To configure 1L liquid phenylalanine medium, add in 950ml deionized water: yeast extract 3g, L-phenylalanine 2g, disodium hydrogen phosphate 1g, NaCl 5g, agar 12g, adjust pH to 5mol / L NaOH 7.0, make up to 1L with deionized water.

[0048] It is assumed that the phenylalanine medium is not written in the usual medium in the procedure of the present invention. When using the present invention to prepare the phenylalanine medium, the experimenter turns on the instrument, selects the custom mode, and inputs 3g for the No. 1 feeding port, 2 g for the No. 2 feeding port, 1 g for the No. 3 feeding port, 5 g for the No. 4 feeding port, and No. 5 feeding port. Feeding port 12g. The experimenter clicks start and the instrument starts running. The subsequent steps were the same as in Example 1.

Abstract

The invention discloses a biological laboratory culture medium automatic configuration device, which relates to the field of biological culture medium configuration and automatic filling, including a solid feeding system, a liquid filling system, a control system, and a surplus material collection system; the solid feeding system includes Solid feeding port, spiral feeding tray, vibrating coil, shock absorbing device, hopper, high-precision weighing device, material outlet, residual material outlet; the liquid filling system includes a suction pipe, a water pump, a flow meter, and a water outlet , an infrared monitor; the control system includes a touch control panel, a control center, a control circuit, and an electric control door; the remaining material collection system includes the electric control door and a drawer-type collection box. The present invention can configure various types of culture medium, eliminating the need for multiple weighing steps in the manual configuration of the culture medium, and liberating the experimenters from time-consuming and laborious repetitive work. The mechanized operation also makes the configuration more uniform each time. Avoid contamination of the culture medium, thus making the experiment more accurate and efficient.

Description

technical field [0001] The invention belongs to the field of biological culture medium configuration and automatic filling, and relates to the application of automatic filling technology in the field of biological culture medium configuration, in particular to an automatic biological laboratory culture medium that integrates solid and liquid filling and is suitable for laboratories. Configure the device. Background technique [0002] In the microbiology laboratory, it is often necessary to configure different kinds of media. At present, the laboratory mainly relies on manual configuration by experimenters. When the experimenter configures the medium, it is necessary to weigh the required solid raw materials several times and measure the deionized water many times. First, the weighing process is complicated and has no technical requirements, but the experimenters spend a lot of energy in the process of configuring the medium, which takes up their time to find and solve prob...
