Description

Technical Field

[0001] The utility model relates to the technical field of experimental equipment, in particular to an integrated organic synthesis console. Background Art

[0002] Currently, common synthesis reactions in organic synthesis laboratories require temperature control, magnetic stirring, nitrogen, vacuum, and water cooling. Temperature control primarily involves oil bath heating, often using a heat-collecting magnetic stirrer, which integrates heating and magnetic stirring. Another temperature control method uses a temperature controller combined with a transformer, with the oil bath placed on a magnetic stirrer to achieve heating and stirring. These are the two most common temperature control and magnetic stirring methods used in laboratories. Nitrogen and vacuum are provided by nitrogen cylinders and vacuum pumps, respectively, while water cooling is directly connected to tap water.

[0003] While integrated temperature control and magnetic stirring are achieved, reducing the size of the system, the temperature control relies solely on a relay mechanism, which results in limited precision. This is particularly true when the voltage is unstable or increases during nighttime troughs, leading to large fluctuations in the oil bath temperature. This makes accurate temperature control difficult, especially at lower temperatures, such as room temperature or 37°C, when precise control is required. Furthermore, the oil bath in a thermal magnetic stirrer is fixed, requiring replacement thermal magnetic stirrers of varying sizes to heat and stir reaction flasks, making it impractical. Furthermore, while the combination of a temperature controller, transformer, and magnetic stirrer can address voltage issues to some extent (by lowering the heating voltage via a transformer or voltage regulator to minimize its impact on temperature control accuracy), a heating and stirring system requires three instruments, requiring significant space and making it inconvenient to use, especially when multiple reactions are being run simultaneously. Furthermore, chemical laboratories typically contain a high concentration of corrosive gases and solvents, which can significantly impact transformers. In particular, voltage regulators are prone to sparking during voltage regulation, posing a significant safety hazard in the laboratory.

[0004] At the same time, no matter which of the above-mentioned heating and stirring methods is used, it is impossible to directly use nitrogen, vacuum, cooling water and other operations, and additional docking is required, which also makes the operation during the synthesis process cumbersome.

[0005] Based on this, this solution provides an integrated organic synthesis console that not only integrates temperature control and stirring, but also integrates functions such as nitrogen, vacuum, and cooling water on the console. At the same time, it basically does not take up any operating space, and fully realizes the integration of operations commonly used in the field of organic synthesis. Utility Model Content
