Barnstead SP133835 Super-Nuova Heated Magnetic Stirrer 120V 10.1A Ceramic

Barnstead SP133835 Super-Nuova Heated Magnetic Stirrer 120V 10.1A Ceramic

The Barnstead SP133835 Super-Nuova is a digital heated magnetic stirrer with a large ceramic hot plate surface, designed for laboratory mixing and heating applications. It provides independent digital control of both heat and stir speed, a programmable timer, and an external temperature probe input — all on a 100-square-inch ceramic work surface suited to larger vessels and multi-sample setups.

Applications

The Barnstead Super-Nuova series heated magnetic stirrer is a standard piece of benchtop laboratory equipment used for combining reagents, maintaining reaction temperatures, and running timed stirring protocols across chemistry, biology, pharmaceutical, and materials science labs. The large ceramic surface accommodates flasks, beakers, and multi-vessel setups that smaller hot plate stirrers can't handle. The RS-232 serial port allows the unit to interface with a computer for automated control or data logging, making it well suited to environments where process documentation is required. The external temperature probe input supports closed-loop temperature control when a thermocouple or PT100 probe is connected directly to the reaction vessel, giving more precise control than surface-temperature sensing alone. These units have been in common laboratory use from the 2000s onward and remain in active service in academic, industrial, and quality-control lab settings today.
