Device for filling culture solution into test tube

Abstract

The invention discloses a device for filling culture solution into a test tube, wherein the device has the advantages that the device is rapider to operate, the quantification accuracy is higher and strains are not apt to be polluted. The device comprises a shell and a sliding box. Sliding grooves are arranged on two internal side walls of the shell. An input tube is communicatively arranged above the shell. An air hole is arranged in one side of the input pipe. An output tube is communicatively arranged below the shell. Sliding rails are arranged on the two side walls of the sliding box. The sliding rails are embedded into the sliding grooves and are in sliding fit with the sliding grooves. An inlet is arranged above the sliding box and an outlet is arranged below the sliding box. The four sides of the sliding box are in contact with the inner walls of the shell and are in sliding fit with the inner walls of the shell.

Description

technical field [0001] The invention relates to a tool, especially a device for dripping culture solution into a test tube. Background technique [0002] In recent years, edible fungi have been widely welcomed by people for their rich nutritional value, and a large number of edible fungi have entered people's diets. Planting edible fungi has also become a major means for farmers to get rich. Planting edible fungi first requires strains. Now the commonly used method of making edible fungus mother species is: fix a funnel on the iron stand, and put a rubber hose on the long tube below the funnel, and fix it under the funnel. A stop clip. When injecting the culture medium into the test tube, hold the test tube with the left hand, with the mouth of the tube facing up, insert the funnel hose into the test tube, pinch the stop clamp with the right hand, so that the culture solution flows into the test tube, loosen the stop clamp after the required amount is reached, and the cultu...

AI Technical Summary

Problems solved by technology

The disadvantage of this device is that the injection of the culture solution into the test tube is slow because of the need to visually check the amount of culture solution flowing into the test tube

In the low temperature season, the culture medium is easy to solidify after a long operation time

At the same time, due to errors in manual visual inspection, the loading capacity is not accurate

When the amount of loading is too small, the inclined surface is too thin, the nutrition is low, and the mycelium is difficult to grow normally; when the amount of loading is too large, the inclined surface is shortened, resulting in the waste of culture medium

In addition, when the amount of culture solution injected into the test tube is too much, it is necessary to pour the excess culture solution back into the funnel. The culture solution is easily contaminated when it flows through the mouth of the test tube, and eventually the bacteria are contaminated.
