[0001] The utility model relates to the technical field of experimental tools, in particular to a PCR plate which is easy to heat. Background Art

[0002] PCR plates are essential tools for molecular biology experiments. Made of plastic and featuring multiple wells, they house PCR reaction systems, which are then run through a thermal cycler after specific reagents are added. They ensure a stable and consistent reaction system, facilitate simultaneous processing of multiple samples, and improve experimental efficiency. Their excellent thermal conductivity ensures uniform temperature, making them indispensable in basic research, medical diagnostics, and the biotechnology industry.

[0003] In some experiments, it is necessary to heat the culture in the culture tubes within the PCR plate. Currently, the most common heating method is generally to use a water bath. However, in actual operation, there are often situations where the conditions for a water bath are not available, which undoubtedly brings great inconvenience to the heating process. Moreover, after the water bath, water droplets will stick to the outer surface of the culture tube, which may affect subsequent experimental operations, such as interfering with measurement results and causing contamination. This series of problems makes how to better heat the culture when water bath conditions are not available a difficult problem that experimenters need to solve urgently. Utility Model Content

[0004] In order to solve the above problems, the utility model proposes a PCR plate that can be heated in a water bath without an external heating source and can quickly dry water droplets on the outer surface of the culture tube at a constant temperature.

[0005] To solve the above technical problems, the present invention proposes a technical solution: a PCR plate that is easy to heat, comprising a PCR plate body and a heating base, wherein a temperature measuring tank is provided above the PCR plate body, the PCR plate body is detachably mounted on the heating base, a support mesh is detachably provided in the middle of the heating base, and ventilation holes are provided on the side walls of the heating base;

[0006] It also includes an air-drying seat that cooperates with the PCR plate body. The PCR plate body can be detachably mounted on the air-drying seat. Fan 1 and Fan 2 are respectively provided on opposite sides of the air-drying seat. Fan 1 and Fan 2 are respectively an inlet fan and an outlet fan. An electric heating rod is provided near the fan in the air-drying seat. The temperature of the electric heating rod is controlled by an adjustment knob fixed on the outer wall of the air-drying seat.

[0007] Furthermore, handles are symmetrically provided on both sides of the PCR plate body, limiting strips are provided at the upper edges of the heating seat and the air-drying seat, and limiting grooves that cooperate with the limiting strips are provided below the PCR plate body.

[0008] Based on the above features, the handle makes it easy for the user to pick up the PCR plate body for heating operations. The limit bar and the limit groove facilitate the PCR plate body to be quickly and stably placed on the heating block or air drying block for heating or air drying operations.

[0009] Furthermore, the supporting mesh plate is made of a bendable elastic material, and a slot matching the supporting mesh plate is provided on the inner side wall of the heating seat, and the edges on both sides of the supporting mesh plate are inserted into the slot.

[0010] Based on the above features, the card slot can stably support and fix the support mesh in the heating seat. The support mesh made of elastic material is easy to bend, and its edges are easy to remove from the card slot, making it easy to disassemble and assemble.

[0011] Furthermore, the air holes are arranged at an angle, the air holes close to the inner end of the heating seat are lower than the air holes close to the outer end of the heating seat, and an easy-tear strip is provided at the air holes on the outer wall of the heating seat.

[0012] Based on the above features, the inclined ventilation holes can prevent water from overflowing during the water bath process, and the easy-tear strips can protect the ventilation holes when the heating base is not in use, preventing dust and impurities from entering the ventilation holes and even contaminating the culture and affecting the experimental results.

[0013] Furthermore, handle grooves are symmetrically provided on both sides of the heating seat.

[0015] Furthermore, the air-drying seat is symmetrically provided with air-drying grooves for placing fans one and two. The air-drying grooves are composed of an upper inclined plate and a lower inclined plate. The junction of the upper inclined plate and the lower inclined plate protrudes toward both sides of the air-drying seat. Fan one, fan two and the electric heating rod are fixed on the lower inclined plate.

[0016] Based on the above features, Fan 1 and Fan 2 are arranged in an air-drying trough composed of an upper inclined plate and a lower inclined plate, which can prevent water droplets on the culture tubes from falling onto Fan 1 and Fan 2 and causing damage. In addition, the wind blown out by the inclined Fan 1 is more concentratedly blown toward the culture tubes on the PCR plate body, thereby improving the air-drying efficiency.

[0017] Furthermore, there are at least two fans 1 and 2, and they are evenly spaced.

[0018] Based on the above characteristics, the air-drying efficiency of the culture tube can be improved, and uniform constant temperature air-drying can be achieved.

[0019] Compared with the prior art, the advantages of the present invention are: the design of the heating seat can not only hold water and place it on an external heating source to heat the culture tubes on the PCR plate body, thereby playing an isolation role to prevent the culture tubes from being overheated and affecting the experimental results or even being damaged, but also use a heating source inside it for heating, and install a supporting mesh plate for isolation, with various heating methods, and is not restricted by external heating conditions, and is flexible and convenient to use. Fan 1 and Fan 2 in the air-drying seat can be responsible for supplying and exhausting air into the air-drying seat respectively, thereby achieving stable and rapid circulation of air in the air-drying seat, and rapidly drying the culture tubes on the PCR plate body. At the same time, the electric heating rod can evenly heat the air blown to the culture tube by Fan 1 under the control of the adjustment knob, so as to maintain a constant temperature environment in the culture tube and ensure the accuracy of the experimental structure.

After the electric heating rod 9 is preheated, the PCR plate body 1 with the culture tube is removed and placed on the air-drying seat 6. Similarly, the limit strip 12 is embedded in the limit groove to fix the PCR plate body 1. The water droplets on the culture tube automatically drip into the pull-out water collection box at the lower end of the air-drying seat 6. Turn on fan 1 7 and fan 2 8. The wind blown to the culture tube by fan 1 7 is heated by the electric heating rod 9 and passes through the surface of the culture tube at a constant temperature. At the same time, fan 2 8 can accelerate air circulation and dry the water on the surface of the culture tube. Finally, the culture tube is removed to inspect the culture, and the water collection box on the air-drying seat 6 is pulled out in time for cleaning.
