Ohaus Guardian 5000 Hot Plate Stirrer, 18L

Ohaus Guardian 5000 Hot Plate Stirrer, 18L: Precision, Safety, and Performance for Your Lab

Elevate your laboratory's capabilities with the Ohaus Guardian 5000 Hot Plate Stirrer. Engineered for exceptional precision in heating and stirring liquid samples, this robust instrument is a cornerstone for any demanding research or routine application. Its durable ceramic top plate ensures uniform heat distribution, crucial for repeatable results, across a wide temperature range from ambient +5°C up to a scorching 500°C. Coupled with an advanced magnetic drive system, the Guardian 5000 delivers highly accurate stirring speeds, adjustable from a gentle 60 rpm to a vigorous 1600 rpm, accommodating diverse sample viscosities and volumes.

Unmatched Safety with SafetyHeat™ System

Your safety and the integrity of your samples are paramount. The Guardian 5000 integrates Ohaus's proprietary SafetyHeat™ system – a sophisticated dual-sensor early detection mechanism. This intelligent system continuously monitors the hot plate, and in the event of a potential overtemperature condition, it automatically and safely shuts down the heating element. An additional "hot top" indicator provides a clear visual alert when the heating surface exceeds 40°C, even if the unit is turned off, preventing accidental burns. Furthermore, an integrated support rod holder facilitates the secure attachment of external temperature probes or accessories, enhancing overall lab safety and experimental setup flexibility.

Intuitive Control and Enhanced Accuracy

Experience superior control and accuracy with user-centric features. The Guardian 5000 offers single-point calibration, significantly improving heating accuracy at specific temperatures, with memory for up to 3 customizable calibration points for both the plate and an optional external temperature probe. The large, crystal-clear LCD display provides real-time readouts of temperature, stirring speed, and critical safety indicators, allowing for effortless monitoring from across the lab. Its intuitive interface simplifies setup and operation, reducing training time and increasing efficiency.

Designed for Durability and Convenience

The innovative SmartHousing™ enclosure is crafted from a chemical-resistant polymer that remains cool to the touch, even during prolonged high-temperature operation. This robust housing not only protects internal components but is also incredibly easy to clean, resisting spills and common laboratory chemicals. A dedicated on/off switch provides immediate power cutoff for the heater, offering an extra layer of safety. The compact footprint and ergonomic design ensure the unit fits seamlessly into any lab space.

Versatile and Robust Performance

Boasting an impressive stirring capacity of up to 18 liters (4.8 gallons) and a spacious 10x10-inch (25.4x25.4mm) ceramic heating platform, the Guardian 5000 is perfectly suited for a wide array of laboratory applications, from chemical synthesis and dissolution to sample preparation and titration. It can confidently support vessel weights up to 14.5 kg (32 lbs), providing stable and consistent performance under heavy loads. Available with both 120V and 230V power supply options, it's ready for global deployment. For applications requiring direct control over sample temperature, a separate, highly accurate temperature probe (sold separately) can be utilized, plugging directly into the unit for closed-loop feedback.
