There are lots of options out there when it comes to heating and stirring in the lab. By far we see the most requests for hotplates and hotplate stirrers but actually these may not be the best option for the application in question. We find many customers have sometimes unrealistic expectations on the sample types they can handle and the stability and accuracy of temperatures they achieve.
When deciding on which heating or stirring option is best for your application, there are a number of points you should consider:
Sample type - chemical properties, volume, physical properties including viscosity
Temperatures in the protocol - what temperature do you need and how accurate do you need this to be?
For our guide to heating and stirring, we will be reviewing the following pieces of benchtop kit - hotplates / hotplate stirrers & magnetic stirrers, overhead stirrers and water baths. Other pieces of equipment that can be used include ovens and incubators which at low enough temperatures can be used in combination with certain stirrer models.
