Glass reactor is made of high borosilicate GG3.3 and famous for its clearance and anti-corrosion character .
The stirring paddle or shaft is made of stainless steel with ptfe coating and bottom discharge valve is also made of high Borosilicate GG3.3 and ptfe material .
Jacketed glass reactor means there is a jacket space between inner layer and outer layer . So you can use this jacket space to make heat or cool liquid circulation . Then those heating or cooling liquid will pass heat or cool to the solvent of glass tank to make those material or solvent to make reaction under vacuum pressure
