• Glassware and containers
• Distillation Apparatus
• Filtration Equipment

This is a reaction device that combines necessary parts for reaction operations, including glass reaction vessels, condensers, and dropping funnels, along with a dedicated frame. It is suitable for various liquid-phase reaction experiments. 【Features】 ● A diverse lineup of containers, ranging from double-tube vessels to triple-tube vessels with medium baffles. * Medium baffle: Our unique obstruction plate structure installed inside the jacket of the glass reaction vessel. The ring-shaped obstruction plate helps to force the circulation of heat transfer media or refrigerants within the jacket, improving the heat transfer coefficient of the reaction vessel. It is very effective in reducing temperature unevenness in the jacket. ● Devices from 300mL to 2L and from 3L to 5L use the same frame. They adopt a reaction vessel similar in shape to a typical glass-lined kettle (10% dished head), making them ideal for considerations of scale-up and scale-down. ● The flash valve minimizes dead space at the bottom of the vessel, achieving minimal liquid pooling to avoid wasting samples. ● The installation area is a space-saving design with a minimum of 380mm x 380mm. It can also be installed within a draft. Customization is possible according to your desired specifications. For more details, please refer to the catalog or feel free to contact us.

• Other physicochemical equipment

By forming a thin film on the inner wall of the evaporation tube with a wiper, low-boiling components can be evaporated in a short time, promoting the movement of the sample. The residence time is also short as it flows down the evaporation tube, allowing for reduced heating time of the sample during operation. Additionally, by reducing pressure, the boiling point can be lowered, making it suitable for processing heat-sensitive samples. It is also possible to recover reusable components of solvents from used solvents and waste liquids. 【Features】 ● Ideal for the separation of heat-sensitive substances that are prone to thermal decomposition (such as vitamins, hormones, enzymes, and aromatic substances). ● Uniform thin film formation due to the use of high-precision tubes and wiper mechanism. ● The evaporator body is made of borosilicate glass, which has excellent corrosion and chemical resistance, and allows for internal observation. ● Non-grease specification at the joint part prevents contamination by impurities. Customization is also possible to meet your desired specifications. For more details, please refer to the catalog or feel free to contact us.

• Concentration Equipment
• Distillation Apparatus

This device is suitable for operations requiring evaporation and distillation under high vacuum. By forming a thin film on the inner wall of the evaporation tube with a wiper, it promotes the movement of the sample, allowing low-boiling components to evaporate in a short time. The short residence time as it flows down the evaporation tube enables operation with reduced heating time for the sample. Furthermore, the presence of a cooler inside the evaporator brings the evaporation surface and condensation surface close together, which helps to suppress pressure increases caused by generated vapor, achieving high vacuum and facilitating low boiling. It is suitable for handling heat-sensitive and high-boiling substances. **Features** - Optimal for the separation of heat-sensitive substances that are prone to thermal decomposition (such as vitamins, hormones, enzymes, and aromatic substances). - Uniform thin film formation due to the use of high-precision tubes and wiper mechanism. - The evaporator is made of borosilicate glass, which offers excellent corrosion and chemical resistance, and allows for internal observation. - Non-grease specification at the joint parts prevents contamination by impurities. Customization is also possible to meet your desired specifications. For more details, please refer to the catalog or feel free to contact us.

The AG! triple-tube reaction vessel features a vacuum jacket and a ring-shaped medium baffle as its main characteristics. The vacuum jacket prevents heat loss and enables more stable temperature control. Additionally, it prevents frost from forming on the surface of the vessel, making internal observation at low temperatures easier. Furthermore, we successfully installed a ring-shaped medium baffle inside the jacket, which improved the heat exchange rate by approximately three times (compared to our company’s previous models). Moreover, the vacuum jacket prevents heat loss and maximizes the capabilities of the constant temperature bath. The design considers scalability! Our triple-tube reaction device is designed with scalability in mind, maintaining a ratio of the inner diameter to height of all reaction layers between 1:1 and 1.5.
