Benchmark Scientific Hotplates and Stirrers provide reliable performance and safe operation for everyday laboratory use. Like our popular 7 x 7-inch series, these hotplates/stirrers feature a durable, chemical-resistant white ceramic top plate and advanced microprocessor controls. The constant monitoring system provides precise control of temperature with rapid heating and faster boiling times. In addition, the powerful motor drive system ensures efficient mixing in larger and more viscous samples.
Temperature and mixing speed can be viewed on the large digital display and safety LED illuminates when the top plate temperature exceeds 50°C. An external temperature probe can also be used for applications that require precise control of sample temperature. The probe provides direct feedback to the microprocessor with constant monitoring and adjustments for maintaining the selected temperature in the sample within +/- 1°C. All models are compatible with borosilicate glass beakers and other vessels up to 20 liters (15 L maximum stirring volume). An optional clamp assembly (H3770-CS) is available for mounting thermometers, temperature probes, etc.
