Description

Technical Field

[0001] This utility model belongs to the technical field of microbial anaerobic fermentation equipment, specifically relating to an anaerobic bottle that can measure the volume of gas produced. Background Technology

[0002] Anaerobic fermentation is an indispensable part of microbial fermentation, especially in geological formations where anaerobic microorganisms play a crucial role in methane gas production. In laboratory anaerobic cultivation, we typically use closed, fixed-space containers—anaerobic culture flasks—which makes it difficult to directly observe gas production and accurately measure the volume of gas produced. Utility Model Content

[0003] To address the technical problem of not being able to visually observe the presence and specific amount of gas produced during anaerobic fermentation, this invention provides an anaerobic bottle that can measure the volume of gas produced.

[0004] This utility model is achieved using the following technical solution: an anaerobic bottle capable of measuring the volume of generated gas, comprising a bottle body, a cap ring, and a drain wedge. The bottle body is transparent and has a first scale indicating the volume, with the scale value increasing from the bottom to the mouth. The cap ring has a flexible sealing membrane for sealing the bottle mouth, which can move up and down at both ends of the cap ring's forming surface. The front end of the drain wedge can extend into the bottle body to squeeze out the liquid inside. The drain wedge has a second scale indicating the volume of the remaining liquid inside the bottle, with the scale value increasing from the rear end to the front end.

[0005] Furthermore, the volume formed by the flexible sealing film and the cap ring is greater than or equal to the volume of the bottle.

[0006] Furthermore, the flexible sealing membrane is a polytetrafluoroethylene membrane.

[0007] Furthermore, the drainage wedge is an inverted frustum shape, and the drainage scale value increases from the large end to the small end.

[0008] Furthermore, the bottle body and the bottle cap are connected by a threaded connection.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] 1. Direct observation of gas generation: Due to the design of the transparent bottle and flexible sealing membrane, users can directly observe the gas generation during anaerobic fermentation, which is convenient for studying and recording the gas dynamics during fermentation.

[0011] 2. Precise gas volume measurement: The first graduation on the bottle clearly displays the gas volume when the bottle is inverted, allowing users to accurately measure the volume of generated gas, facilitating data collection and analysis. The second graduation on the drain wedge allows for precise control of the liquid volume inside the bottle.

[0012] 3. Corrosion resistance: Using polytetrafluoroethylene (PTFE) membrane as the sealing material not only ensures the airtightness of the bottle, but also its excellent corrosion resistance and high temperature resistance make the anaerobic bottle suitable for a variety of anaerobic fermentation experiments, extending its service life.

[0013] 4. Easy to operate and maintain: The bottle body and cap ring are connected by threads, which makes it easy to open, close and seal. The operation is simple and does not require complicated tools. At the same time, the replacement and cleaning of the polytetrafluoroethylene membrane is also relatively easy, which helps to maintain the hygiene of the equipment and the accuracy of the experiment.

[0018] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of an anaerobic bottle capable of measuring the volume of gas produced.

[0019] like Figure 1 As shown, an anaerobic bottle capable of measuring the volume of generated gas includes a bottle body 1, a bottle cap ring 2, and a drain wedge 4. The bottle body 1 is a transparent bottle body with a first scale indicating the volume, the scale value increasing from the bottom to the mouth of the bottle. The bottle cap ring 2 is provided with a flexible sealing membrane 3 for sealing the mouth of the bottle body. The flexible sealing membrane 3 can move up and down at both ends of the forming surface of the bottle cap ring 2. The front end of the drain wedge 4 can extend into the bottle body 1 to squeeze out the liquid inside the bottle body 1. The drain wedge 4 is provided with a second scale indicating the volume of the remaining liquid inside the bottle body 1, the scale value increasing from the rear end to the front end.

[0020] In this embodiment, the bottle body 1 is cylindrical, and the bottle body 1 is threadedly connected to the bottle cap ring 2. The bottle body 1 and the bottle cap ring 2 can be closed by twisting the threads to achieve a seal. The drain wedge 4 is an inverted frustum shape, and the drain scale value increases from the large end to the small end. The flexible sealing membrane 3 is a polytetrafluoroethylene membrane, and the volume formed by the flexible sealing membrane 3 and the bottle cap ring 2 is greater than or equal to the volume of the bottle body 1.

[0021] like Figure 2 As shown, during use, add liquid 5 to bottle 1, place bottle cap ring 2 on the bottle mouth, insert flexible sealing film 3 into bottle 1, press the drain wedge 4 into flexible sealing film 3 according to the desired volume scale to drain excess liquid 5, then tighten bottle cap ring 2 to bottle 1, remove drain wedge 4 and you can observe. After gas production, bubbles and gas 6 can be directly observed in the space, as shown. Figure 3 As shown, when it is necessary to measure the gas production volume, the bottle is inverted. The flexible sealing membrane 3 forms a plane under the influence of gas pressure, and the gas volume 6 can be read through the first scale on the bottle body 1.
