Description

Technical Field

[0001] The utility model belongs to the technical field of taking devices, and in particular relates to a quick taking device for testing pH of microbial culture medium. Background Art

[0002] The pH test of microbial culture medium refers to the process of measuring the acidity and alkalinity of the culture medium used to cultivate microorganisms. Since different microorganisms have specific requirements for the pH value of the growth environment, the appropriate pH range can ensure the normal growth, reproduction and physiological functions of microorganisms. Usually, pH meters or pH test paper are used for testing. The pH meter measures the hydrogen ion concentration through electrodes to obtain an accurate value, while the pH test paper relies on color changes to determine the approximate pH range against the colorimetric card. By testing the pH of the microbial culture medium, the pH value of the culture medium can be adjusted in time to provide a suitable growth environment for microorganisms, thereby improving the success rate of microbial culture and the accuracy of the experiment.

[0003] In the existing process of pH testing of microbial culture media, sampling is generally done manually or using basic automated equipment. This method is not only inefficient and time-consuming, but also prone to cross-linking between test tubes due to human errors or insufficient equipment precision during operation, affecting the accuracy and reliability of the test results. Improvements are needed. To this end, a rapid sampling device for pH testing of microbial culture media is proposed. Utility Model Content

[0022] In the rapid access device for testing the pH of microbial culture medium, the base 1 is used to support the entire device. When quickly accessing the microbial culture medium in multiple groups of test tubes, the multiple groups of test tubes are respectively inserted into the test tube openings 4 of the vertical plate 3, and clean water is injected into the liquid injection port 5;

[0023] After that, the motor 131 is started, the output shaft of the motor 131 rotates to drive the screw rod 133 to rotate, and the screw rod 133 rotates to drive the movable bar 132 to move horizontally on the installation frame 2, thereby driving the vertical plate 3 to move horizontally, so that the test tube port 4 and the test tube are directly opposite to the through port 6 and the liquid collection tube 7, and the liquid collection tube 7 is sucked and discharged through the pump body 8.

[0033] In the rapid access device for testing the pH of microbial culture medium, the base 1 is used to support the entire device. When quickly accessing the microbial culture medium in multiple groups of test tubes, the multiple groups of test tubes are respectively inserted into the test tube openings 4 of the vertical plate 3, and clean water is injected into the liquid injection port 5;

[0034] After that, the motor 131 is started, the output shaft of the motor 131 rotates to drive the screw rod 133 to rotate, and the screw rod 133 rotates to drive the movable bar 132 to move horizontally on the installation frame 2, thereby driving the vertical plate 3 to move horizontally, so that the test tube port 4 and the test tube are directly opposite to the through port 6 and the liquid collection tube 7, and the liquid collection tube 7 is sucked and discharged through the pump body 8. The lifting member 10 is composed of an electric push rod 101 and a connecting rod 102.

After the pump body 8 is started, the culture medium is sucked into the liquid collection tube 7 by the negative pressure, and the culture medium is discharged into the collection box 9. During this process, the limit block 12 slides on the slide 11 to ensure that the liquid collection tube 7 is lifted and lowered smoothly, thereby avoiding sampling errors caused by shaking;

[0035] After the above operations, the vertical plate 3 is moved so that the liquid injection port 5 is aligned with the through hole and the liquid collection tube 7. The liquid collection tube 7 extracts clean water to flush the culture medium remaining in the liquid collection tube 7.
