Overhead Stirrer Provides an Effective Tool for Rapid Screening

An independent report (www.asynt.com/download_files/84.pdf) demonstrates how the Asynt Vortex overhead stirrer system provides an effective tool for rapid screening of a range of reaction conditions in parallel - an essential for efficient process development.

The Asynt Vortex overhead stirrer system is designed to enable three reactions to be stirred simultaneously using a single overhead stirrer motor and heated to temperatures to over 200°C.

In the report - researchers evaluate the consistency of mixing delivered by a Vortex system controlling three reaction vessels by measuring the bulk mixing and extraction times in each vessel and comparing this data with a stand-alone vessel.

From the experiments conducted - the researchers concluded that no significant difference was measured in the mixing capability of a reaction vessel connected to a Vortex system when compared to a stand-alone single reaction vessel set-up. In addition the mixing characteristics across the three reaction vessels set up on the Vortex system were, within experimental error, the same. Therefore the researchers concluded that the Vortex system constitutes a useful addition for laboratories conducting parallel synthesis minimising both the necessary laboratory footprint required and reducing the cost significantly by replacing three overhead stirrers with one. Further the integration of the Vortex with an Asynt DrySyn Multi hotplate allows heating of the three reaction vessels using a single hotplate also reducing the space requirements and costs when compared to a standard set-up without the mess and safety concerns of using a conventional oil bath system.
