Distillation head with condenser sealed to a Vigreux column. Top thermometer joint is a 10/18 for use with a 25mm immersion thermometer.

* High Quality Glass Material: Made of borosilicate 3.3 glass with heavy wall, uniform and flawfree. it boasts excellent chemical resistance, allowing it to withstand the corrosion of various chemical reagents commonly used in distillation processes.
* Joints：short path with 14/20 joint, with a 10/18 outer joint to accept thermometers adapter
* Vacuum jacketed: The vacuum double layer provides excellent thermal insulation to prevent the product from decomposing at high heating temperatures.
* Applications: Suitable for experiments requiring precise control of reaction conditions in organic chemistry, analytical chemistry, and related fields, such as the separation and purification of trace substances.
