Abstract
Description
Technical Field
[0001] This utility model relates to the field of experimental device technology, specifically to a device for preparing microbial slant culture medium. Background Technology
[0002] Test tube slant culture medium is a special form of solid culture medium. Its preparation process involves dispensing molten culture medium raw materials such as agar into test tubes while hot, followed by sterilization by high-pressure steam. After the culture medium cools and solidifies, the culture medium in the test tubes presents a slant shape. This shape design is mainly to facilitate the expansion and transfer of bacterial strains and long-term preservation.
[0003] However, currently, there is a lack of dedicated equipment for preparing test tube slant agar cultures. Typically, laboratory staff simply place the aliquoted test tubes on the lab bench, using books or other objects to maintain a slight angle so that the culture medium forms the desired slant during cooling. While this method is simple and easy, it's difficult to guarantee the consistency of the test tube tilt angle.
[0004] The difference in the tilt angle of the test tubes leads to significant differences in the slant area of the prepared culture medium. This results in variations in the distribution density and growth environment of the bacterial strains on the medium, affecting their physiological state and genetic stability.
[0005] Furthermore, existing techniques for preparing slant agar culture media in test tubes have the limitation of not being able to adjust the tilt angle of the test tubes. Therefore, a new solution is needed to address these issues. Utility Model Content
[0006] Therefore, the purpose of this utility model is to provide a device for making microbial slant culture medium, so as to solve the technical problems that the test tube angle cannot be adjusted and the tilt angle of multiple test tubes cannot be consistent.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A device for preparing microbial slant culture medium includes a base frame with a perforated periphery and two columns located above the base frame. A test tube rack is hinged between the two columns. A lead screw is provided below the movable end of the test tube rack on the base frame. The lead screw passes through the base frame and has a handwheel at the bottom end.
[0009] By adopting the above technical solution, the test tube rack, as a mature product, can achieve the simultaneous and consistent arrangement of multiple test tubes. By suspending and hinged the test tube rack, and then using a screw rod to support the bottom surface of the test tube rack, the angle of the test tube rack can be adjusted and fixed. This not only solves the problem of not being able to adjust the tilt angle of the test tubes in the existing technology, but also ensures the consistency of the tilt angle of the test tubes.
[0010] The present invention is further configured such that auxiliary plates are provided on both sides of the movable end of the test tube rack of the base frame, and an arc-shaped channel is opened on the auxiliary plate along the movable direction of the test tube rack, and a protrusion protrudes from the movable end of the test tube rack toward the arc-shaped channel.
[0011] By adopting the above technical solution, the arc-shaped channel plays a guiding role, ensuring that the protrusion can move along the path of the arc-shaped channel.
[0012] The present invention is further configured such that a ball is provided at the top of the lead screw.
[0013] By adopting the above technical solution, the top surface of the sphere has no sharp edges or corners, which can reduce the damage to the bottom surface of the test tube rack during the movement of the lead screw.
[0014] The present invention is further provided that the bottom surface of the test tube rack is provided with a thickened plate.
[0015] By adopting the above technical solution, the bottom surface of the test tube rack can be prevented from being deformed by pressure.
[0016] The present invention is further configured such that the test tube rack is transparent.
[0017] By adopting the above technical solution, it is convenient to observe the internal condition of the test tube rack and test tubes.
[0018] In summary, the present invention has the following main advantages:
[0019] 1. By suspending and hinged the test tube rack, and then using a screw rod to press against the bottom surface of the test tube rack, the angle of the test tube rack can be adjusted and fixed. This not only solves the problem of not being able to adjust the tilt angle of the test tubes in the existing technology, but also ensures the consistency of the tilt angle of the test tubes.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0023] The embodiments of this utility model will be described below based on its overall structure.
[0024] A device for preparing microbial slant culture medium, such as Figure 1 As shown, the device includes a base frame 1 with openwork on all sides and two uprights 2 located above the base frame 1. A test tube rack 3 is hinged between the two uprights 2. The test tube rack 3 is preferably transparent and tilted when no external force is applied. A lead screw 4 is provided below the movable end of the test tube rack 3 on the base frame 1. The lead screw 4 passes through the openwork in the middle of the base frame 1 and is threadedly connected to the top plate of the base frame 1. A handwheel 5 is provided at the bottom end of the lead screw 4. By rotating the handwheel 5, the height of the lead screw 4 can be adjusted, thereby adjusting the movable end of the test tube rack 3 that the top of the lead screw 4 abuts against, and thus adjusting the tilt angle of the test tubes 11 inside the test tube rack 3.
[0025] To ensure more stable movement of the test tube rack 3, in some embodiments, the base frame 1 is provided with auxiliary plates 6 on both sides of the movable end of the test tube rack 3. The auxiliary plates 6 have arc-shaped channels 7 along the direction of movement of the test tube rack 3, and the movable end of the test tube rack 3 has protrusions 8 protruding into the arc-shaped channels 7. The center of the arc-shaped channels 7 is located on the rotation axis of the test tube rack 3, ensuring that the protrusions 8 can move along the path of the arc-shaped channels 7.
[0026] In some embodiments, the top of the lead screw 4 is provided with a ball 9, and the bottom surface of the test tube rack 3 is provided with a thickened plate 10. The top surface of the ball 9 has no sharp edges or corners, which can reduce the damage to the bottom surface of the test tube rack 3 during the movement of the lead screw 4. At the same time, the thickened plate 10 can prevent the bottom surface of the test tube rack 3 from being deformed by pressure.
[0027] In summary, the present invention has the following advantages: by suspending and hinged the test tube rack 3, and then by using the screw rod 4 to push against the bottom surface of the test tube rack 3, the angle of the test tube rack 3 can be adjusted and fixed. This not only solves the problem that the tilt angle of the test tube 11 cannot be adjusted in the prior art, but also ensures the consistency of the tilt angle of the test tube 11.
