Guardian 7000 Ohaus

Sample Preparation Magnetic Stirrer

The OHAUS Guardian 7000 Magnetic Hotplate Stirrers exemplify safety and top-tier performance across all applications. Every model incorporates the SafetyHeatTM system, a leading-edge feature in the industry, providing dual-system monitoring for safe heating applications. An vivid LCD display hosts user-friendly icons, temperature, speed, and duration settings for comprehensive performance monitoring throughout the lab.

Key Features:

• SmartHousing™: This innovative design is chemical resistant and easily cleaned, directing any potential bspillages away from internal components and the glass control panel.
• SmartPresence™ and SmartLink™: Automatically power down the heater if no user activity is detected for a set ‘time out' duration or a connected smartphone is no longer detected through Bluetooth.
• SafetyHeat™: Dual safety control systems cease heating operations to prevent overheating.
• Robust Motor: A resilient magnet with software-controlled ramp speed guarantees stirring precision, ranging from 60 to 1,600 rpm, for secure magnetic coupling in viscous applications.
• SmartHeat™ and SmartRate™: Allows users to set the maximum unit temperature and rate of temperature and speed variances. It provides the capacity for the storage of five multi-stage programs.

Available Models:

• E-G71HS07C: Compact square plate model (178 x 178 mm) with a 15-litre flow rate; ceramic plate; heats up to 500°C.
• E-G71HS10C: Large square plate model (254 x 254 mm) with an 18-litre flow rate; ceramic plate; heats up to 500°C.
• e-G71HSRDM: Model with a round plate (135Ø mm) with a 20-litre flow rate; aluminium plate; heats up to 380°C.

Applications:
Useful for thermosensitive chemistry and biology, heat fixation, solution pH optimization, solution sterilization, endothermic reactions, organic material denaturation, sample and solution preparation, buffers and solubilization reagents, and preparation media boiling.

Display:
Backlit LCD for temperature, speed, and time, glowing green during heating and stirring phases, hob over-temperature indicator, and intuitive icons for adjustable settings.

Accessories:
Main power cable, included, an 8' stainless steel RTD temperature probe, PTFE coated stir bar (1.5'), and protective hood all come as standard.

Connectivity:
USB port for the programming of recurring applications, enhancing safety via SmartLink™ technology. Long-range user detection capabilities via the OHAUS Bluetooth dongle accessory (sold separately).

Construction:
SmartHousing™, that is heat-insulated and chemically-resistant, an IP21 rating, a tempered glass front panel, control knobs, an heaters’ disconnect switch, integrated support-rod holder, with an easily cleaned ceramic or aluminium plate.

Additional Features:
Temperature indicator light, audible alarm, SmartHeat™ temperature limitation, SafetyHeat™ heating halt in case of malfunctioning, temperature calibration for five probes and five plate setpoints, temperature-priority function and SmartRate™ functions.
