Glass reactor GRL-20CE

Overview of the Glass Reactor GRL-20CE

The Glass reactor GRL-20CE is a modern laboratory unit designed for carrying out chemical reactions and processes that require precise control and continuous observation. It is built around a 20 l borosilicate glass vessel with a 9 l jacket, combining excellent chemical and thermal stability with a fully transparent design. This transparency lets researchers monitor reaction progress directly and adjust conditions as the process develops, making the reactor well suited to research and development work in chemical and pharmaceutical laboratories.

Design and Performance

The borosilicate glass construction provides the chemical resistance and thermal stability needed for demanding reaction work across a broad temperature window of -80°C to 200°C, when paired with a suitable circulator. The jacketed vessel allows a heat-transfer fluid to circulate through the 9 l jacket for controlled heating and cooling, while the integrated DSC350 controller manages process parameters. A 370 W BLDC motor drives the stirrer across an adjustable range of 20 to 500 rpm, supporting both gentle mixing and more vigorous agitation depending on the reaction. The vessel is rated for operation under vacuum down to -0.1 MPa, which is useful for distillation, degassing and reactions requiring reduced pressure.

Laboratories that need larger or alternative jacketed configurations may also consider the comparable jacketed double glass reactor, which shares the same emphasis on temperature-controlled reaction processing.

Applications

The GRL-20CE is intended for chemical synthesis, mixing, distillation, crystallization and other temperature-sensitive processes that benefit from precise control and visual monitoring. Its versatile feature set and robust glass design make it suitable for complex reaction sequences in research and development environments, where reproducibility and the ability to observe the reaction directly are important. Typical workflows include solvent reactions under vacuum, reactions requiring controlled heating or cooling through the jacket, and processes where adjustable stirring speed influences product quality.

To support the reactor in everyday use, laboratories often complement it with supporting glassware made from borosilicate 3.3 glass, such as beakers and measuring cylinders, for preparing and transferring reagents. Together with the appropriate temperature-control and vacuum equipment, the Glass reactor GRL-20CE provides a dependable platform for controlled chemical and pharmaceutical reaction work.
