Ohaus Guardian 7000 Hot Plate Stirrer, 18L

Ohaus Guardian 7000 Hot Plate Stirrer, 18L: Precision, Safety, and Performance for Demanding Labs

The Ohaus Guardian 7000 Hot Plate Stirrer is engineered to deliver unparalleled precision heating and stirring for a wide range of laboratory applications. Designed for chemists, biologists, and researchers in academic, industrial, and quality control environments, this robust unit offers advanced capabilities that ensure superior performance, user safety, and consistent results. With an expansive temperature range from ambient +5°C up to 500°C and a powerful stirring speed spanning 60 to 1600rpm, it's perfectly suited for complex chemical syntheses, dissolution studies, sample preparation, and other demanding tasks requiring exacting control. Its durable ceramic top plate provides uniform heat distribution across the entire surface, ensuring even sample heating, while also being exceptionally resistant to chemicals and easy to clean. The reliable magnetic drive system guarantees consistent and powerful stirring, even with viscous samples up to 18 liters.

Key Features & Benefits:

• Exceptional Accuracy and Reproducibility: Achieve highly reproducible results with precisely controlled temperature and stirring speed. The included 20cm stainless steel temperature probe (PT1000) provides direct, accurate feedback for sample temperature regulation, critical for sensitive reactions. The unit also features advanced calibration options, allowing users to store up to five specific plate and probe setpoints for various experimental protocols, ensuring maximum accuracy tailored to your workflow. SmartRate™ technology further enhances control by allowing precise ramp rates for both temperature and stirring speed, preventing thermal shock and ensuring gentle, controlled processes.
• Comprehensive Safety Systems: The Guardian 7000 prioritizes user and sample safety with multiple intelligent features:
  • SafetyHeat™ System: This advanced monitoring system constantly checks internal hardware and software functions, proactively identifying and addressing potential faults before overheating can occur, providing continuous protection.
  • SmartHeat™: Safeguard your valuable samples from thermal degradation by setting a maximum heating temperature, preventing accidental overheating and ensuring experimental integrity.
  • Hot Top Indicator: A prominent warning light illuminates when the plate surface temperature exceeds 40°C, even if the unit is off, preventing accidental burns.
  • SmartPresence™ Technology: An integrated proximity sensor automatically detects when a user steps away from the unit. After a customizable period of inactivity, the heating function can be set to automatically shut off, conserving energy and enhancing unattended operation safety.
  • SmartLink™: For remote monitoring and control, this Bluetooth® feature (requires dongle, sold separately) links the stirrer to your device. If the connection is lost, heating will automatically discontinue, adding an extra layer of safety when operating away from the immediate vicinity.
• Intuitive & User-Friendly Design: The large, vibrant LCD display provides crystal-clear visibility of all operational parameters, including temperature, stirring speed, and safety settings, even from a distance across the lab. SmartHousing™ technology ensures the robust exterior is not only chemical-resistant and easy to maintain but also designed to remain cool to the touch during operation, further enhancing user safety and comfort. The intuitive interface allows for straightforward setup and adjustment of parameters, minimizing training time.
• Robust Construction & Versatility: Built to withstand the rigors of daily laboratory use, the Guardian 7000 features a durable ceramic heating platform and a sturdy design capable of supporting up to 14.5kg (32lbs). Its large 10 x 10 inch (254 x 254mm) platform accommodates a wide variety of glassware and lab vessels.
