Problems solved by technology

[0003] However, the automation of the sampling device of the bioreactor in the prior art is relatively low, which requires manual sampling, which increases the workload and labor intensity of the staff, and in the sampling process When pulling the sampling bottle to move, it is easy to cause the bottle to fall, and in serious cases, the bottle will break and the sample will flow out. In addition, after the sampling device is used, it needs to be cleaned manually, and the cleaning efficiency is low. After cleaning, the liquid in the suction tube The cleaning water is not easy to clean, it needs to be air-dried naturally, if the residual liquid inside is not cleaned in time, it will easily absorb dust and other impurities inside, which will affect subsequent use

Embodiment 1

[0051] refer to Figure 1-13 , a sampling device based on biological experimental equipment, including a workbench 1, a bioreactor 2 is fixedly connected to the top of the workbench 1, the top inner wall and bottom inner wall of the bioreactor 2 are rotatably connected to the same stirring rod 4, and the workbench The bottom inner wall of 1 is fixedly connected with a stepping motor 57, the output shaft of the stepping motor 57 extends into the bioreactor 2 and is fixedly connected with the stirring rod 4, and the top of the stirring rod 4 extends above the bioreactor 2 and is fixedly connected There is an internal gear ring 5, the top of the bioreactor 2 is provided with a connected sampling tube 3, the top of the bioreactor 2 is provided with a sampling box 12, and the top of the sampling box 12 is provided with a connected through hole 45, and the workbench 1 One side of the top is provided with a moving assembly for moving the sampling box 12 up and down, the bottom of the...

Embodiment 2

[0067] Embodiment two: if Figure 13 Shown in -15, a kind of sampling device based on biological experiment equipment, the difference between this embodiment and embodiment one is: the top of circular plate 50 is fixedly connected with rubber pad 54, when holding sample bottle 20 from through hole 45 places When putting into the sampling case 12, the rubber pad 54 can prevent the sample bottle 20 from being in rigid contact with the bottom inner wall of the sampling case 12.

[0068] However, as those skilled in the art know, the operating principle and wiring method of the rotating motor 10, the drive motor 26, the vacuum pump 38, the water pump 41, the solenoid valve 49, the circular plate 50, the telescoping rod 56 and the stepper motor 57 are Commonly seen, they all belong to conventional means or common knowledge, and will not be described in detail here, and those skilled in the art can make arbitrary selections according to their needs or convenience.

Abstract

The invention belongs to the technical field of biological experiment equipment, particularly relates to a sampling device based on biological experiment equipment and a use method thereof. According to the scheme, the sampling device comprises a workbench, the top of the workbench is fixedly connected with a biological reaction box, the inner wall of the top and the inner wall of the bottom of the biological reaction box are rotationally connected with a same stirring rod, and a stepping motor is fixedly connected to the inner wall of the bottom of the workbench. The device is simple in structure and convenient to operate. A moving ring can drive a sample containing bottle to move by starting a driving motor, the bottle body is prevented from toppling and breaking in the moving process of the sample containing bottle, air in the sample containing bottle can be extracted through a vacuum pump to form negative pressure, and then a sample can be extracted. In addition, cleaning and drying are integrated, so that the cleaning efficiency is improved, and the influence on subsequent use caused by residual liquid on the inner walls of the biological reaction box, a sampling pipe, a sampling connecting pipe and a sampling barrel can be prevented.

Description

technical field [0001] The invention relates to the technical field of biological experimental equipment, in particular to a sampling device based on biological experimental equipment and a method for using the same. Background technique [0002] Bioengineering requires reactions within a bioreactor. A bioreactor is any manufacturing or engineering device that provides a biologically active environment. In one context, a bioreactor is a process involving biological or biochemically active Vessels for chemical processes produced, which can be carried out aerobically or anaerobically, these biological reaction devices are usually cylindrical, with volumes ranging from a few liters to several cubic meters, often made of stainless steel. [0003] But the automation degree of the sampling device of the bioreactor of the prior art is low, needs manual sampling, increases the workload and labor intensity of the staff, and when pulling the sampling bottle body to move in the samplin...
