Safety Heat System Protects the Lab

An industry-leading early detection system that uses two independent safety controls to continuously monitor the electronics and shut off the heating before an overtemperature condition occurs.

Powerful, Consistent Stirring Performance

Precise stirring from 60 to 1600 rpm is made possible by the design of a powerful motor, strong magnet, and software-controlled ramp rate, ensuring secure magnetic coupling for viscous applications.

Easy to Read LCD Display With Everything You Need to Know

The bright LCD display includes large temperature and speed settings, intuitive icons, and a prominent hot top indicator – all designed to quickly and easily monitor performance from across the lab. Designed for Durability and Reliability with the Exclusive SmartHousing The SmartHousing is chemical resistant with an innovative, easy-to-clean design that channels spill away from internal components and the angled control panel.

FAQ-Guardian 5000 Hotplate Stirrers

What types of applications is the Guardian 5000 Series hot plate stirrer designed for?

Guardian 5000 Series are designed for safety and simplicity in all academia, research, and industrial applications. Therefore, the design ensures proper mixing and temperature control of the top plate or your sample when used with the optional temperature probe.

Which features are built into the Guardian 5000 Series to make it safe for use in academic settings?

The Guardian 5000 Series are designed for durability, reliability, and safety with its exclusive SmartHousing and SafetyHeat. SmartHousing remains cool to the touch at all temperature settings, is chemical resistant, and is an easy-to-clean design that channels away spills from internal components and the front panel.  In other words, the SafetyHeat system protects the lab with an industry-leading early detection system that uses two independent safety controls to continuously monitor the electronics and shuts off the heating before an overtemperature condition occurs.

What type of Guardian top plate material best suits the lab, ceramic or aluminum?

Ceramic and aluminum top plates are both suitable for lab use and each material has its benefits. Most importantly, Ceramic top plates are chemical resistant and safer if working with corrosive chemicals that may splash onto the plate surface. They can withstand higher temperatures up to 500 °C and can be wiped clean.

The white surface of a ceramic top plate is preferable for quantitative chemical analysis or other work where clear visibility of the sample color is required.

The edges of a ceramic top plate may not be as hot as the center. This may not be suitable if uniform heating over the entire plate surface is needed for the application. Aluminum top plates offer more uniform temperature over the entire heating surface and will not crack or chip, and will withstand accidental handling.

To avoid thermal shock, glassware should be used on ceramic top plates, and heating of metallic vessels should be avoided. Above all, Ceramic top plate units are also not suitable for sandbaths or any vessel that may reflect heat back onto the surface which may cause thermal shock.
