Description
Technical Field
[0001] The utility model belongs to the technical field of temperature control experimental devices, in particular to a temperature control timing device for preventing centrifuge tubes from being polluted. Background Art
[0002] In PCR experiments, constant temperature heating is often required, with the temperature as high as 100°C for ten minutes. The conventional DKT200-4 constant temperature metal bath does not have a timing device, and it needs to be taken out one by one. There is a time difference in the process and it is not safe, which is easy to cause experimental contamination. The centrifuge tube cools down slowly after being taken out, and the approximate temperature cannot be judged. At this time, because the air in the centrifuge tube expands due to long-term heating, if the experimenter takes it out directly, it is easy to cause the lid to explode, causing experimental contamination, which is unsafe for the experimenter and needs to be taken out slowly. In addition, due to the large number of tubes, it is easy to cause time deviation, which has a certain impact on the experiment.
[0003] Conventional constant temperature metal baths do not have a timing device and require the use of a quartz timer. Although multiple times can be timed at the same time, it is easy to make mistakes when doing large-scale experiments. After all are taken out, they need to be cooled to room temperature and then centrifuged. The cooling process is slow and the approximate temperature cannot be known.
[0004] In view of the above situation, the existing experimental methods and equipment are modified, and a movable anti-pollution temperature control timing device is designed to avoid pollution and protect the experimenters, so that the experiment can be completed more accurately and conveniently. Utility Model Content
[0005] The purpose of the utility model is to provide a temperature control timing device for preventing centrifuge tube contamination, so as to solve the problems raised in the above background technology. The following technical solution is provided: A temperature control timing device for preventing centrifuge tube contamination, comprising:
[0006] The upper end of the support foot is fixed with a support plate, the interior of the support plate is provided with a sink, and the bottom end wall of the sink is evenly provided with a placement opening for holding the centrifuge tube;
[0007] A cooling component is rotatably arranged in the middle of the support leg and is used to cool the centrifuge tube;
[0008] A hinged part is arranged on one side of the supporting foot, an explosion-proof cover plate is movably connected to the hinged part, the explosion-proof cover plate can be buckled with the supporting foot, and a timer and a temperature control device are fixedly arranged in the middle of the explosion-proof cover plate.
[0009] In this technical solution, the centrifuge tube needs to be heated at a constant temperature for a period of time in the PCR experiment, the constant temperature is 100°C, and the constant temperature time is ten minutes. When in use, first cover the device above the DKT200-4 constant temperature metal bath device, and the metal bath device is provided with a socket for the heating placement port. At this time, the placement port and the socket in the metal bath device are aligned up and down, and then the centrifuge tube is inserted into the placement port, and the metal bath device is turned on to heat the placement port.
[0010] When the centrifuge tube is heated for a long time, the air in the tube expands due to the heat. If the experimenter tries to take it out directly, the cover may explode, causing experimental contamination and endangering the experimenter. Therefore, when the centrifuge tube is heated, the explosion-proof cover and the support feet should be fastened at the same time.
[0011] Conventional thermostatic metal baths do not have a timing device and require the use of a quartz timer. Although multiple times can be timed at the same time, it is easy to make mistakes when doing large-scale experiments. After all are taken out, they need to be cooled to room temperature and then centrifuged. The cooling process is slow and the approximate temperature cannot be known. In order to ensure the accuracy of the constant temperature time, a timer and temperature control device are used to achieve precise control of the constant temperature heating time of the centrifuge tube.
[0012] In any of the above technical solutions, further, the cooling component includes a swing rod, one end of which is horizontally rotatably arranged in the middle of the support leg, and a fan is fixedly arranged at the other end of the swing rod.
[0013] The support leg comprises a support rod, the interior of the support rod is in a cavity shape, an adjusting nut is rotatably provided at the lower end of the support rod, a lead screw is threadedly connected to the middle part of the adjusting nut, and a supporting part is fixedly provided at the lower end of the lead screw.
[0014] In the present technical solution, after the constant temperature heating of the placement port is completed, the device needs to be separated from the metal constant temperature bath. After separation, the legs arranged at the four ends of the device make the lower end of the centrifuge tube suspended in the air without contact. At this time, the operator turns the rocker arm to align the fan with the bottom of the placement port. The fan accelerates the flow of air at the lower end of the placement port, shortening the time for the placement port to return to room temperature, thereby completing the experiment more accurately and conveniently.
[0015] When the height of the device is not enough, the operator can turn the adjustment nut by himself, and the adjustment nut and the lead screw are threaded to extend the lead screw and change the length of the legs to adapt to the experimental requirements. At the same time, the four limbs of the device can support the centrifuge tube to be suspended in the air without contact with the desktop, which can prevent the desktop from being contaminated by pollutants and affecting subsequent experiments. The small fans on the four limbs are located on both sides when the shelf is heated in the metal bath, and are in a closed state at this time. When the shelf is taken out and needs to be cooled, the fan rotates inside. After starting, the centrifuge tube can be cooled more quickly, which is conducive to shortening the experimental process.
[0016] In any of the above technical solutions, further, an operating table is fixedly provided at the middle of the explosion-proof cover. A timer and a temperature control device for temperature monitoring are fixedly provided on the operating table. The explosion-proof cover is made of transparent glass.
[0017] In this technical solution, when the experiment needs to be heated at 100℃ for ten minutes, the centrifuge tube can be placed in the placement port and covered with the explosion-proof cover. After the whole is placed in the constant temperature metal bath, the timer is started for timing. When the constant temperature heating is finished, the whole is taken out and placed aside. When the centrifuge tube cools to room temperature, the temperature control device will sound a reminder, and then the centrifuge tube can be taken out for subsequent experiments. The explosion-proof cover is made of transparent explosion-proof glass, which can be used to observe the status of the centrifuge tube during the constant temperature heating of the centrifuge tube.
[0018] The beneficial effects of the utility model are as follows: by providing a support plate and an explosion-proof cover, the centrifuge tube is suspended and isolated from the desktop when the metal bath device is heating, reducing the contact between the centrifuge tube and the desktop to avoid contamination. At the same time, by independently provided timers and temperature control devices, when the temperature drops to a certain range, a reminder can be issued to indicate the operator, making the experiment more accurate. The integrated design of the entire device makes the time control of the constant temperature more precise, which is conducive to the conduct of the experiment. Increasing the air flow under the centrifuge tube by a fan can speed up the cooling of the centrifuge tube, which is conducive to shortening the experimental process.

[0027] Embodiment 1:
[0028] like Figure 1-3 As shown, this embodiment provides a temperature control timing device for preventing centrifuge tube contamination, comprising:
[0029] A support leg 10, a support plate 11 is fixedly provided at the upper end of the support leg 10, a sink 12 is provided inside the support plate 11, and a placement opening 13 for holding a centrifuge tube is evenly opened at the bottom end wall of the sink 12;
[0030] A cooling component 20 is rotatably disposed at the middle of the support leg 10 and is used to cool the centrifuge tube;
[0031] The hinge 30 is arranged on one side of the support leg 10, and an explosion-proof cover plate 40 is movably connected to the hinge 30. An operating table 41 is also fixedly arranged at the middle of the explosion-proof cover plate 40. A timer 50 and a temperature control device 60 for temperature monitoring are fixedly arranged on the operating table 41. The explosion-proof cover plate 40 is made of transparent glass.
[0032] The explosion-proof cover plate 40 can be buckled with the supporting leg 10 and a timer 50 and a temperature control device 60 are fixedly provided in the middle of the explosion-proof cover plate 40 .
[0033] In the present technical solution, the centrifuge tube needs to be heated at a constant temperature for a period of time in the PCR experiment, the constant temperature is 100°C, and the constant temperature time is ten minutes. When using this device, first cover the device above the DKT200-4 constant temperature metal bath device, which is provided with a jack for the heating placement port 13. Conventional constant temperature metal baths do not have a timing device and require the use of a quartz timer. Although multiple times can be timed at the same time, it is easy to make mistakes in remembering the time when conducting large-scale experiments; after all are taken out, they need to be cooled to room temperature and then centrifuged. The cooling process is slow and the approximate temperature cannot be known. In order to confirm the accuracy of the constant temperature time, a timer 50 and a temperature control device 60 are used to achieve precise control of the constant temperature heating time of the centrifuge tube.
[0034] During the experiment, the placement port 13 is aligned with the socket in the metal bath device, and then the centrifuge tube is inserted into the placement port 13, the metal bath device is turned on and the placement port 13 is heated. After the whole is placed in the constant temperature metal bath, the timer 50 is started for timing. When the constant temperature heating is finished, the whole is taken out and placed aside. When the centrifuge tube cools to room temperature, the temperature control device 60 will sound a reminder, and then the centrifuge tube is taken out for subsequent experiments. The explosion-proof cover 40 is made of transparent explosion-proof glass, which can be used to observe the state of the centrifuge tube during the constant temperature heating of the centrifuge tube. The air in the centrifuge tube expands due to long-term heating. If the experimenter directly takes it out, it is easy to cause the cover to explode, causing experimental pollution and unsafe for the experimenter. Therefore, when the centrifuge tube is heated, the explosion-proof cover 40 is buckled with the support foot 10 at the same time.
[0035] In a preferred embodiment of the present invention:
[0036] like Figure 2-5 As shown, specifically, the cooling assembly 20 includes a swing rod 21 , one end of which is horizontally rotatably disposed at the middle of the support leg 10 , and a fan 22 is fixedly disposed at the other end of the swing rod 21 .
[0037] The support leg 10 supports a rod 14, the interior of the support rod 14 is in a cavity shape, and an adjusting nut 16 is rotatably provided at the lower end of the support rod 14, a lead screw 15 is threadedly connected to the middle of the adjusting nut 16, and a support portion 17 is fixedly provided at the lower end of the lead screw 15. The support portion 17 is made of rubber material. And the pitch of the lead screw 15 is 2mm.
[0038] In the present technical solution, after the constant temperature heating of the placement port 13 is completed, the device needs to be separated from the metal constant temperature bath. After separation, the legs 10 arranged at the four ends of the device make the lower end of the centrifuge tube suspended in the air without contact. At this time, the operator rotates the rocker arm 21 to align the fan 22 with the bottom of the placement port 13. The fan 22 accelerates the flow of air at the lower end of the placement port 13, shortening the time for the placement port 13 to return to room temperature, thereby completing the experiment more accurately and conveniently.
[0039] When the height of the device is not enough, the operator can turn the adjustment nut 16 by himself, and the pitch of the nut 16 and the lead screw 15 is selected as a standard part of 2mm. The adjustment nut 16 and the lead screw 15 are threaded so that the lead screw 15 is extended and the length of the support leg 10 is changed to adapt to the experimental requirements. At the same time, the four limbs of the device can support the centrifuge tube to be suspended and not in contact with the desktop, which can prevent the desktop from being contaminated by pollutants and affecting subsequent experiments. The small fans on the four limbs are located on both sides when the shelf is heated on the metal bath, and are in a closed state at this time. When the shelf is taken out and needs to be cooled, the fan rotates inside. After starting, the centrifuge tube can be cooled more quickly, which is conducive to shortening the experimental process. The lead screw and thread with a pitch of 2mm are used. The rotating nut can realize the increase of the height of the four brackets. Even if the operating table is in a non-horizontal position, it can ensure that the position of the centrifuge tube will not be offset during the heating process of the centrifuge tube, ensuring the quality of the constant temperature metal bath.
[0040] The embodiments of the present application are described above in conjunction with the accompanying drawings. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
