Description

Technical Field

[0001] The utility model relates to the field of centrifuge tube auxiliary equipment, in particular to a constant temperature centrifuge tube rack. Background Art

[0002] Centrifuge tube racks are special equipment used in laboratories to store and manage centrifuge tubes. They come in a variety of specifications and colors to accommodate different types of centrifuge tubes. The design of a centrifuge tube rack usually contains multiple grids, each of which can hold a centrifuge tube separately, to ensure the safety of the sample and avoid confusion. The material selection of the centrifuge tube rack is also very important. Commonly used materials include polyethylene (PE), polycarbonate (PC), polypropylene (PP), etc. Among them, polypropylene PP is widely used due to its good performance. The material of the centrifuge tube rack matches the centrifuge tube to ensure stability and safety during the experiment.

[0003] Centrifuge tubes are commonly used consumables in laboratories. They are mainly used in conjunction with centrifuges to load experimental liquids and place them in centrifuges for centrifugal separation. Centrifuge tubes can be divided into plastic centrifuge tubes and glass centrifuge tubes according to their materials. The use of centrifuge tube racks not only helps to keep the laboratory clean, but also improves experimental efficiency because experimenters can quickly find the required centrifuge tubes.

[0004] Many biological laboratories have certain temperature requirements for substances temporarily stored in centrifuge tubes. They need to ensure temperature stability within a certain time range to ensure that the activity or potency of the experimental samples is not affected by temperature.

[0005] Existing centrifuge tube racks are mostly made of plastic. When encountering experiments with complex operation processes, the items in the tubes are exposed to room temperature for a long time, which leads to the inactivation of the samples or the reduction of the potency. In addition, most existing centrifuge tube racks cannot tolerate high temperatures. In laboratories with sterility requirements, they cannot be sterilized at 121°C, so their sterilization effect cannot be guaranteed. Utility Model Content

[0006] The utility model is aimed at the above-mentioned problems and specifically designs a constant temperature centrifuge tube rack to meet the requirement of temperature stability of experimental samples within a certain period of time and ensure the validity of experimental data.

[0007] To achieve the above purpose, the utility model provides a constant temperature centrifuge tube rack, including a main body and a bottom cover, the main body is provided with centrifuge tube holes, a constant temperature cavity is provided inside the main body, a coolant is filled in the constant temperature cavity, and the bottom cover is installed at the bottom of the main body.

[0008] By adopting the above technical scheme, a centrifuge tube hole is set on the main body. During the experiment, the centrifuge tube can be placed in the centrifuge tube hole. Since the constant temperature cavity inside the main body is filled with a refrigerant, the constant temperature centrifuge tube rack is placed in a refrigerator for a period of time before the experiment to maintain a constant temperature. After being taken out, the temperature change value can be kept within the required range for a certain period of time.

[0009] Furthermore, the inner diameter of the centrifuge tube hole is matched with the outer diameter of the centrifuge tube, and the hole diameter of the centrifuge tube has various specifications, all of which are matched with the outer diameters of various specifications of laboratory centrifuge tubes.

[0010] By adopting the above technical solution, a variety of regular centrifuge tube holes are arranged on the upper surface of the main body, which can be suitable for the placement and constant temperature of a variety of centrifuge tubes.

[0011] Furthermore, a filling hole is provided on the bottom cover, and a screw cover is installed on the filling hole.

[0012] By adopting the above technical solution, the filling hole can be used to connect the pipeline, fill the refrigerant into the constant temperature cavity, and then tighten it with the screw cap.

[0013] Furthermore, the filling hole is a countersunk hole relative to the bottom cover, and the cap of the screw cover is sunk in the countersunk hole.

[0014] The countersunk hole design allows the screw cap to be recessed into the bottom surface after being tightened into the filling hole, thus preventing it from being left unused.

[0015] Furthermore, a shock-absorbing layer is attached to each inner wall of the centrifuge tube hole, which can effectively prevent the centrifuge tube from vibrating and breaking when moving.

[0016] Preferably, the main body is an organic silicone material with thermal conductive filler added.

[0017] In summary, the utility model provides a constant temperature centrifuge tube rack, whose main body is an organic silicone material with added thermal conductive filler. Its lower thermal conductivity can reduce the temperature change rate of the contents, and can also pre-treat the test tube rack when the temperature slightly exceeds the required temperature, while ensuring that the constant temperature time is extended without causing the temperature to deviate from the required temperature. Adding a refrigerant inside it can maintain the temperature, and utilizing the high temperature resistance and acid and alkali resistance of silicone to meet the requirements of high temperature and wet heat sterilization and the general needs of the laboratory, improves the defect that the original centrifuge tube rack cannot maintain the temperature of the contents of the centrifuge tube stable within a certain period of time, can meet the temperature stability of the experimental samples within a certain period of time, and ensure the validity of the experimental data.

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. Example

[0029] like Figure 1-5 As shown, this embodiment provides a constant temperature centrifuge tube rack, including a main body 1 and a bottom cover 2, the main body 1 is an organic silicone material with added thermal conductive filler; centrifuge tube holes 11 of various specifications are arranged on the top of the main body 1, the spacing is the same as that of the centrifuge tube racks commonly used in the market, the diameter and shape match the 2ml, 5ml, 15ml, 50ml, 225ml, and 500ml centrifuge tubes commonly used in the market, and the hole height is 2 / 3 of the height of the centrifuge tube of the corresponding specification.

[0030] A shock-absorbing layer is attached to each inner wall of the centrifugal tube hole 11 , a constant temperature chamber 12 is arranged inside the main body 1 , a refrigerant is filled in the constant temperature chamber 12 , and a bottom cover 2 is installed at the bottom of the main body 1 .

[0031] The bottom cover 2 is provided with a filling hole 21 , on which a screw cover 22 is installed; the filling hole 21 is a countersunk hole relative to the bottom cover 2 , and the cap of the screw cover 22 is sunk into the countersunk hole.

[0032] The working principle of the constant temperature centrifuge tube rack of the utility model is:

[0033] 1. The main body of the centrifuge tube rack of the utility model is an organic silica gel material with added fillers, and the fillers include metal oxides (Al2O3, MgO, BeO, etc.) or metal nitrides (SiN, AlN, BN, etc.). The thermal conductivity of these fillers is related to their particle size distribution, morphology, interface contact and the degree of bonding within the molecule. Fibrous or foil-shaped thermal conductive fillers usually provide better thermal conductivity. The temperature resistance range of ordinary silica gel is usually between -40℃ and 160℃. This makes them perform well when used in daily environments, such as silica gel accessories and gifts. In addition, in terms of acid and alkali resistance, the performance of silica gel is relatively good.

[0034] 2. Taking advantage of these characteristics of silica gel, we use suitable silica gel materials to make high temperature resistant constant temperature silica gel centrifuge tube racks. We use the lower thermal conductivity of silica gel to reduce the temperature change rate of the contents, and can also pre-treat the test tube rack when the temperature slightly exceeds the required temperature, while ensuring that the constant temperature time is extended, and the temperature will not deviate from the required temperature. We use the high temperature resistance and acid and alkali resistance of silica gel to meet the requirements of high temperature and moist heat sterilization and the general needs of the laboratory.

[0035] 3. When working, first fill the appropriate coolant into the constant temperature chamber 12 of the centrifuge tube rack through the filling hole 21. Put the centrifuge tube rack in a refrigerator or a thermostat for more than 4 hours to keep the temperature constant. When using, take it out of the refrigerator or the thermostat, insert the centrifuge tube into the hole and perform the experimental operation. The temperature of the substance in the centrifuge tube can change within 5°C within 40 minutes.

[0036] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
