[0025] See Figure 1 , Figure 2 and Figure 3 This application discloses an external reagent storage device. The external reagent storage device includes a housing 1, a water bath 2, and a weighing assembly 3. In some embodiments, an operation panel 11 is mounted on the top of the housing 1, and the operation panel 11 is provided with a first placement port 12 and a second placement port 13; the water bath 2 is provided with a water bath cavity 21, and the top of the water bath 2 is connected to the bottom of the operation panel 11, with the first placement port 12 communicating with the water bath cavity 21; the weighing assembly 3 is disposed below the second placement port 13. Preferably, by integrating the water bath 2 and the weighing assembly 3 into the operation panel 11 of the housing 1, the operator can perform water bath heating and weighing of reagents through the first placement port 12 and the second placement port 13 respectively, eliminating the need to transfer reagents between multiple workstations, facilitating operation, and effectively improving experimental efficiency.
[0026] See Figure 1 andFigure 3 In some embodiments, the reagent to be heated in a water bath is pre-contained in a corresponding container. When performing water bath heating, the container containing the reagent can be placed into the water bath 2 through the first placement port 12. In this embodiment, the water bath chamber 21 of the water bath 2 is pre-contained with a liquid, such as water, for transferring heat to the object or reagent being heated. Preferably, it also includes a first reagent bottle 28. The first reagent bottle 28 is disposed at the first placement port 12 and extends into the water bath chamber 21. Thus, the reagent requiring water bath heating can be injected into the first reagent bottle 28, so that the water bath chamber 21 performs water bath heating on the reagent injected into the first reagent bottle 28.
[0027] See Figure 1 and Figure 3 In some embodiments, the system further includes a water drain bracket 22 and a water drain through hole 23. The water drain bracket 22 is provided with a placement cavity 24. The water drain bracket 22 is connected to the first placement port 12 and extends into the water bath cavity 21. The water drain through hole 23 is distributed around the water drain bracket 22 and is used to connect the placement cavity 24 and the water bath cavity 21. Preferably, by placing a container containing reagents into the placement cavity 24, the water leak bracket 22 supports and fixes the container containing reagents. Simultaneously, the water leak through-hole 23 connects the placement cavity 24 and the water bath cavity 21, causing the container containing reagents to be immersed in water. This allows the water in the water bath cavity 21 to transfer heat to the reagents, achieving water bath heating. Optionally, multiple water leak through-holes 23 are distributed around the periphery of the water leak bracket 22, allowing water in the water bath cavity 21 to flow evenly into the placement cavity 24, resulting in a uniform temperature within the placement cavity 24 and maintaining a consistent temperature between the placement cavity 24 and the water bath cavity 21, thereby ensuring uniform heating of the reagents. In this embodiment, the first reagent bottle 28 is placed into the placement cavity 24 through the first placement port 12, and the water in the water bath cavity 21 flows evenly into the placement cavity 24 through the water leakage hole 23 to heat the reagent contained in the first reagent bottle 28 in a water bath.
[0028] See Figure 1 and Figure 3In some embodiments, a heating assembly 4 is also included. The heating assembly 4 includes a heating base 41, a heat insulation seat 42, and a heating element 43. The heat insulation seat 42 is mounted on the bottom of the water bath 2, the heating base 41 is mounted on the heat insulation seat 42, and the heating element 43 is disposed on the bottom of the heating base 41. Optionally, the heat insulation seat 42 is made of insulating and heat-insulating material. Optionally, the bottom of the water bath 2 has a through hole communicating with the water bath cavity 21, and the heat insulation seat 42 is mounted in the through hole. Optionally, a sealing ring is provided between the heat insulation seat 42 and the water bath 2 to improve the sealing performance between the heat insulation seat 42 and the water bath 2. Optionally, the heat insulation seat 42 has a slot for mounting the heating base 41, and the top of the heating element 43 abuts against the bottom of the heating base 41. Thus, the heating element 43 heats the water contained in the water bath chamber 21 through the heating base 41, so that the water in the water bath chamber 21 heats the reagent contained in the first reagent bottle 28 in a water bath. At the same time, the heat insulation seat 42 insulates the heating base 41 and the water bath chamber 2, blocking the transfer of heat between the heating base 41 and the water bath chamber 2, reducing heat loss, and improving the heating efficiency of the heating base 41 in heating the water in the water bath chamber 21.
[0029] See Figure 2 and Figure 3 In some embodiments, a temperature sensing component is also included, comprising a first temperature probe 25 and a second temperature probe 44. The first temperature probe 25 is disposed in the water bath 21, and the second temperature probe 44 abuts against the heating element 43. In this embodiment, the temperature of the water bath 21 is monitored by the first temperature probe 25 to ensure it remains constant during the experiment, avoiding the impact of temperature fluctuations on the accuracy and reliability of the experiment. Simultaneously, the temperature of the heating element 43 is monitored by the second temperature probe 44 to understand the working status of the heating element 43, helping to ensure that the heating element 43 works normally and avoiding equipment failure due to insufficient heating or overheating. Thus, the temperatures of the water bath 21 and the heating element 43 can be monitored simultaneously, effectively ensuring normal equipment operation, improving the accuracy and reliability of the experimental process, and also helping to save energy and time.
[0030] See Figure 2 and Figure 3In some embodiments, a drain pipe 26 and a drain valve 27 are also included. The drain pipe 26 connects the inlet of the drain valve 27 to the water bath chamber 21. Preferably, by opening and closing the drain valve 27, the drain pipe 26 is connected to or cut off from the outside, thereby realizing the drainage and water storage of the water bath chamber 21. In this embodiment, when filling the water bath chamber 21 with water, the drain valve 27 can be closed to fill the water bath chamber 21 with water from the first placement port 12, or the drain valve 27 can be opened to supply water from the outside water supply pipe to the water bath chamber 21 through the drain valve 27 and the drain pipe 26. When the water bath chamber 21 stores enough water, the drain valve 27 is closed to stop the water supply to the water bath chamber 21. When draining the water bath chamber 21, the drain valve 27 is opened to discharge the water in the water bath chamber 21 to the outside through the drain pipe 26 and the drain valve 27.
[0031] See Figure 1 and Figure 2 In some embodiments, the weighing assembly 3 includes a pressure sensor 31, a mounting bracket 32, and a support plate 33. The support plate 33 is disposed below the second placement port 13, and the pressure sensor 31 is connected to the bottom of the support plate 33. The operation panel 11 is connected to the pressure sensor 31 through the mounting bracket 32. Optionally, the pressure sensor 31 is mounted on the mounting bracket 32, and the top of the mounting bracket 32 is connected to the bottom of the operation panel 11, thereby mounting the pressure sensor 31 below the operation panel 11. Simultaneously, the support plate 33, connected to the top of the pressure sensor 31, is placed below the second placement port 13. Thus, the reagent to be weighed can be pre-contained in a corresponding container. During weighing, the container containing the reagent can be placed on the support plate 33 through the second placement port 13 to drive the pressure sensor 31 to detect pressure changes on the support plate 33, thereby achieving the weighing of the reagent.
[0032] See Figure 1 and Figure 2In some embodiments, there are multiple second placement ports 13; each second placement port 13 contains a second reagent bottle 35, the bottom of which abuts against the top of the weighing assembly 3. Preferably, the bottom of the second reagent bottle 35 abuts against the support plate 33, so that the pressure sensor 31 can detect the pressure change caused by the reagent injected into the second reagent bottle 35, thereby achieving the weighing of the reagent. Optionally, each of the multiple second placement ports 13 contains a second reagent bottle 35, so that multiple reagents required in the experiment can be injected into different second reagent bottles 35 in sequence. In this way, since each injection of reagent can cause a pressure change, multiple reagents can be weighed by a single pressure sensor 31 without moving the weighed second reagent bottle 35, thus improving weighing efficiency. Furthermore, the second reagent bottle 35 can also be a water tank for storing water.
[0033] See Figure 2 and Figure 3 In some embodiments, a limiting groove 34 is further included, which is disposed on the top of the support plate 33, and the second placement port 13 is disposed opposite to the limiting groove 34. Preferably, the limiting groove 34 limits the container placed on the support plate 33 through the second placement port 13, ensuring that the container can be stably fixed on the support plate 33. In this embodiment, the limiting groove 34 and the second placement port 13 are arranged in a one-to-one correspondence, and the bottom of the second reagent bottle 35 is fixed in the limiting groove 34, so that the second reagent bottle 35 is reliably fixed on the support plate 33, thereby driving the pressure sensor 31 to accurately detect the pressure change caused by the reagent injected into the second reagent bottle 35, and achieving accurate weighing.
[0034] In some embodiments, a cell preparation apparatus includes an external reagent storage device as described above.
[0035] See Figure 1 , Figure 2 and Figure 3In some embodiments, the reagent to be heated in a water bath is injected into the first reagent bottle 28. The heating element 43 heats the water contained in the water bath chamber 21 through the heating base 41, so that the water in the water bath chamber 21 heats the reagent contained in the first reagent bottle 28. At the same time, the temperature of the water bath chamber 21 and the heating element 43 are monitored simultaneously by the first temperature probe 25 and the second temperature probe 44, which effectively ensures the normal operation of the equipment and improves the accuracy and reliability of the experimental process. Furthermore, the reagent to be weighed can be injected into the second reagent bottle 35, which drives the pressure sensor 31 to detect the pressure change caused by the reagent injected into the second reagent bottle 35, thereby realizing the weighing of the reagent. This allows the operator to perform water bath heating and weighing of the reagent at the same workstation, without the need to transfer the reagent between multiple workstations, which is convenient for operation.
