🧪 Product Overview:

The inner chamber holds the reaction solution for stirring and processing, while the outer jacket allows temperature regulation via circulating fluids (hot or cold water/oil). This flask supports stirring reactions under normal or negative pressure and is perfect for:

  • Temperature-controlled chemical reactions

  • Solution distillation and reflux

  • Fine chemical, pharmaceutical, and new material synthesis

Its design ensures optimal heat transfer, safe sealing, and ease of operation during laboratory workflows.
