Gate Scientific has developed an innovative hotplate stirring system for heating and mixing liquid samples for research, product development and quality control applications in materials and chemistry intensive industries such as life science, biotech, pharmaceutical, glass and CASE (coating, adhesive, sealant, elastomer) manufacturing.

The Wi-Fi Precision Hotplate uses a SmartSense Stirbar to wirelessly monitor the actual temperature within the stirred media.

Most hot plate stirrers measure the hot plate or heat source temperature. Researchers often need another thermometer or temperature sensor within the stirred liquid. The hot plate temperature is not typically controlled by the external thermometer, so users have to set the hot plate to a slightly higher temperature than the desired temperature of the liquid being stirred.

In Gate Scientific’s system, a magnetic stirring bar, called SmartSense Stirbar, contains a RFID wireless temperature sensor and power source.

The RFID-enabled SmartSense Stirbar measures the temperature of the liquid and continuously relays data to the digitally programmable hotplate stirrer via wireless communication. Based on real-time information from the stir bar, the Gate Precision Hotplate Stirrer will self-adjust the heat setting to maintain the temperature as specified. Dual sensing elements ensure accurate temperature measurements.

The SmartSense technology and the strong neodymium magnet comes encased in inert EFEP fluoropolymer for a broad range of applications.
