20L Reactors

A jacketed glass reactor consists of an inner glass vessel enclosed within an outer jacket, allowing circulation of temperature-controlling fluids. This provides precise temperature control for reactions with heat-sensitive materials suitable for processes that require heating or cooling such as chemical synthesis, pharmaceutical research, and material testing. 

There are 2 types of jacketed glass reactors

  • Single jacketed glass reactors

These reactors have one outer jacket that allows for temperature control of the reactor's contents.
Made suitable for: Laboratory applications with precise temperature regulation during chemical reactions or processes.

  • Dual jacketed glass reactors

Designed with both an inner and an outer jacket, these reactors allow for the circulation of cooling or heating fluids in-between.
Made suitable for: applications that require more precise and efficient thermal management because of its enhanced temperature control.

There are 2 types of non-jacketed glass reactors:

  • Single non-jacketed glass reactors

- these reactors lack an outer jacket and do not provide direct temperature control.
- Made suitable for: simple processes that do not require precise temperature regulation such as basic mixing, dissolution, or general reactions.

  • Dual non-jacketed glass reactors

- while these reactors lack an outer jacket, they possess two separate reaction chambers. It is purposed for experiments involving two different reactants that need to be combined or reacted simultaneously.
- Made suitable for: applications requiring separate reaction environments or parallel reactions, where precise temperature control is not a primary concern.


The Ai R-series of 20L jacketed and non-jacketed glass reactors are designed for various laboratory applications. Each reactor features adjustable stirring speeds and a constant pressure feeding funnel that allows you to add material to the vessel at a uniform and controlled speed. The built-in condenser makes it possible to recover some materials, also at a controlled rate of speed.
