Scientific instruments are tools for precision measurement, and their precision and reliability must be an order of magnitude higher than the object being measured. Therefore, although there are not as many components as airplanes, the systematic design is also beyond imagination. The chromatographic column, as a consumable, is a separation center, just like the heart. High pressure, tightness and flow rate stability are required. And the oven needs to be kept at a constant temperature. To prevent leakage, maintain constant temperature, pressurized flow, every link, can not be slack. For materials, seals, and fluid mechanics, a high foundation is required.

The method for checking whether the instrument leaks: pinch off the external vacuum skin tube, and observe whether the vacuum gauge on the instrument can keep the instrument leak-free for five minutes. If there is air leakage, check whether the sealing ring on each sealing joint and rotating shaft is effective. On the contrary, the instrument is normal to check the vacuum pump and vacuum pipeline.

FT-3L double glass reactor

Model: FT-3L

Features: FT-3L double-layer glass reactor has an electric constant speed stirring system, condensation and dropping system, and the sandwich of the kettle body needs external heating or cooling circulation equipment. While stirring the material, the circulating hot solution or cooling liquid is injected through the interlayer to heat or cool the material in the kettle at a constant temperature. When the material is heated, the evaporation efficiency can be improved under vacuum conditions (vacuum device needs to be connected). The solvent vapor is cooled into liquid when passing through the glass condensing coil (cooling device needs to be connected), which can be returned to the kettle or recovered through the valve at the lower part of the reflux elbow. After the reaction is completed, the materials can be discharged from the side discharge port at the bottom of the kettle.

Working principle

This machine has an electric constant speed stirring system, condensation and dropping system, and the sandwich of the kettle body needs external heating or cooling circulation equipment. While stirring the material, the circulating hot solution or cooling liquid is injected through the interlayer to heat or cool the material in the kettle at a constant temperature. When the material is heated, the evaporation efficiency can be improved under vacuum conditions (vacuum device needs to be connected). The solvent vapor is cooled into liquid when passing through the glass condensing coil (cooling device needs to be connected), which can be returned to the kettle or recovered through the valve at the lower part of the reflux elbow. After the reaction is completed, the materials can be discharged from the side discharge port at the bottom of the kettle.

This series of products use the need to support the vacuum device, high temperature or low temperature circulation device and other components of the system device.
