A Hotplate Magnetic Stirrer is an essential laboratory tool used to heat and mix liquids simultaneously. By combining a heating plate with a rotating magnetic field, the instrument creates consistent mixing while maintaining controlled temperatures. The Vertex Analytical range includes compact units for routine laboratory use as well as advanced models with programmable functions and external temperature monitoring. Users can choose between a basic Magnetic Stirrer with Hotplate for everyday mixing tasks or a more advanced digital hotplate stirrer for applications that require accurate temperature regulation and timed operation. Several models feature ceramic-coated heating surfaces that improve chemical resistance while supporting easy cleaning after use.

Digital Temperature and Speed Control

Selected models feature a clear digital display that allows users to monitor and adjust stirring speed, temperature, and operating time. Speed ranges extend up to 1500 rpm, providing flexibility for both gentle mixing and vigorous agitation.

Dual Temperature Monitoring

When a PT1000 temperature probe is connected, the system displays the actual liquid temperature in real time. Consequently, users can achieve more accurate temperature control during critical laboratory processes. Advanced models support two operating modes:

• Direct hotplate temperature monitoring
• External probe-based liquid temperature measurement

Multiple Plate Configurations

Users can therefore select the most suitable configuration for their vessels and workflow requirements. The range includes:

• Round top plate models (135 mm diameter)
• Square top plate models (135 × 135 mm and 160 × 160 mm)
• Large-format heating surfaces for higher volume applications

Strong Magnetic Drive System

Each Magnetic Hotplate Stirrer uses a brushless motor and powerful magnetic coupling to maintain stable stirring performance. Depending on the model, stirring capacities range from 2 L up to 20 L of water.

Corrosion-Resistant Heating Surface

Several models incorporate a ceramic hotplate magnetic stirrer design featuring a ceramic-coated aluminum or stainless-steel surface. As a result, the heating plate resists many common laboratory chemicals while supporting efficient heat transfer.

Applications

In addition, the integrated probe holder can accommodate temperature probes, pH electrodes, and other sensors during mixing processes. The Laboratory Hotplate Stirrer range is suitable for:

• Chemical reagent preparation
• Buffer and media preparation
• Pharmaceutical formulation work
• Environmental testing laboratories
• University teaching laboratories
• Research and development facilities
• Water analysis laboratories
• Industrial quality control laboratories

Performance and Convenience

The compact footprint helps maximize valuable bench space. A major advantage of a Hot Plate Magnetic Stirrer is its ability to streamline laboratory workflows. Instead of using separate heating and mixing devices, users can perform both functions on a single benchtop instrument. For laboratories requiring elevated temperatures, the high temperature hotplate stirrer models can reach temperatures of up to 550°C while maintaining controlled stirring performance.

Advanced models offer:

• Programmable timers from 1 minute to 12 hours
• Adjustable temperature settings
• Fine speed adjustments
• External temperature feedback
• Large-capacity stirring options
• Included support stand and probe accessories

Safety and Reliability

Safety remains important in every laboratory environment. Therefore, selected models include built-in over-temperature protection that automatically disconnects heating if the safe operating limit is exceeded.

Additional safety features include:

• Brushless motor technology
• Stable low-speed operation
• Temperature monitoring functions
• Probe-based feedback control
• Durable heating surfaces
• Anti-corrosion construction
