The invention discloses a bacterial colony sampling device for biotechnology. The device comprises a fixed seat, an injector and test tubes, a culture dish is arranged on the inner side of an inserting block, the top of the fixed seat is fixedly connected to a pipe sleeve, the outer side of the pipe sleeve is movably connected to telescopic pipes, one sides, far away from the culture dish, of thetwo telescopic pipes are fixedly connected to a mounting plate I, the injector is arranged between two liquid storage bottles, the bottom of the injector is fixedly communicated with a main opening inthe top of a demultiplexer, the sides, directly close to the culture dish, of the two telescopic pipes are fixedly connected to a mounting plate II, and a plurality of test tubes are arranged in themounting plate II. The device has the following beneficial effects: sampling at multiple positions can be conducted at the same time by connecting the injector with the demultiplexer, stratified sampling and diluted sampling can be conducted through liquid discharging of a liquid storage tank, an anti-skid pad can prevent the situation that sampling is affected due to device displacement caused bymistaken touch of the device during sampling, the sampling height is controlled by inserting and pulling a fixing bolt to adjust a telescopic rod, and different sampling devices are installed.
Description
technical field [0001] The invention relates to a sampling device, in particular to a biotechnology colony sampling device, which belongs to the field of biological sampling devices. Background technique [0002] With the development of biotechnology and the popularization of biological products, biotechnology has become more and more important. In the production of biotechnology, colony sampling research is required. From a statistical point of view, sampling is mainly divided into random sampling and non-random sampling. Among them, random sampling includes multiple sampling methods such as equidistant sampling, stratified sampling, and dilution sampling, and sampling devices are used in sampling research. [0003] At present, the existing biotechnology colony sampling device is bulky and complicated to operate, and cannot perform non-random sampling, and cannot perform simultaneous multi-sampling during sampling, which not only reduces sampling efficiency and quality, but...
