Ohaus Guardian 7000 Hot Plate Stirrer, 15L

Ohaus Guardian 7000 Hot Plate Stirrer, 15L

The Ohaus Guardian 7000 Hot Plate Stirrer, 15L, represents a pinnacle in laboratory equipment, engineered for unparalleled precision, safety, and reliability in handling liquid samples. Designed for demanding scientific applications, these hot plate stirrers provide advanced heating and stirring capabilities, ensuring consistent and accurate results across a wide range of experiments.

Key Features & Benefits:

• Exceptional Temperature Control: Achieve precise thermal management with heating capabilities from ambient +5°C up to a scorching 500°C. The durable ceramic top plate ensures uniform heat distribution, eliminating hot spots and ensuring consistent sample temperatures, crucial for sensitive reactions. Its smooth, inert surface also makes cleanup effortless, minimizing cross-contamination risks.
• Powerful & Precise Stirring: The robust magnetic drive system delivers a broad stirring speed range from 60 to an impressive 1600 rpm. This versatility allows for gentle mixing of delicate biological samples to vigorous agitation of viscous solutions, ensuring homogeneous reactions and optimal dissolution.
• Enhanced Accuracy with Multi-Point Calibration: A dedicated 20cm temperature probe provides direct, in-solution temperature feedback, offering superior accuracy compared to plate surface readings. The advanced single-point calibration feature, combined with five calibration points for both the plate and probe, guarantees maximum consistency and adherence to strict experimental protocols, vital for reproducible research.
• SmartRate™ Settings for Controlled Processes: Implement controlled ramp rates for both temperature and stirring speed. This intelligent feature allows for gradual heating or cooling and progressive mixing, preventing thermal shock to samples and ensuring optimal reaction kinetics and material synthesis.
• Comprehensive SafetyHeat™ System: Ohaus prioritizes user and sample safety. The integrated SafetyHeat™ system employs dual internal sensors to continuously monitor the instrument, proactively preventing overtemperature conditions. In the event of a fault, the system automatically cuts off heating, safeguarding your experiment and lab environment.
• SmartHeat™ Protection for Sample Integrity: Define a maximum sample temperature limit, preventing accidental overheating and degradation of your valuable samples. This feature provides an additional layer of security, especially for temperature-sensitive compounds or biological reagents.
• Advanced SmartPresence™ & SmartLink™ Safety Features: A built-in proximity sensor intelligently detects user presence. If no user is detected within a set timeframe, the heating automatically shuts off, mitigating risks associated with unattended operation. Furthermore, the Bluetooth® SmartLink™ capability (with an optional dongle) offers wireless control and will stop heating if the connection to the wireless dongle is lost, enhancing remote safety.
• User-Friendly Design for Seamless Operation: Monitor your experiment at a glance with a bright, intuitive LCD display featuring large digits for easy readability, even from a distance. The innovative SmartHousing™ exterior is not only chemical-resistant for long-term durability and easy cleaning but also engineered to remain cool to the touch during operation, enhancing user comfort and safety.
