Product description

Premium magnetic stirrer with advanced safety, precise control, and smart features.

The OHAUS Guardian 7000 Magnetic Hotplate Stirrers offer outstanding safety and top-tier performance across all applications. Equipped with SafetyHeat™, these devices provide dual system integrity monitoring to guarantee safe operation in heating processes. The bright LCD display, complete with intuitive icons, enables real-time monitoring of temperature, speed, and duration from anywhere in the laboratory.

Key OHAUS Innovations:

  • SmartHousing™: Features an innovative, chemical-resistant design that diverts liquid spills away from internal parts and glass control panels.
  • SmartPresence™ and SmartLink™: Automatically deactivate the heater if no user is detected post 'time out,' or if Bluetooth connectivity is lost.
  • SafetyHeat™: Employs dual safety controls for constant electronics monitoring, preventing overheating by shutting off the heater if necessary.
  • Powerful Motor: Ensures stirring precision, with software-controlled ramp speeds from 60 to 1,600 rpm for effective magnetic coupling in viscous environments.
  • SmartHeat™ and SmartRate™: Allow maximum temperature settings and control over rapid or gradual changes in temperature and speed. The scheduler enables storage for five multi-stage programs.

Available Models:

  • E-G71HS07C: Small square plate (178 x 178 mm), 15-liter flow rate, ceramic plate, heats up to 500°C.
  • E-G71HS10C: Large square plate (254 x 254 mm), 18-liter flow rate, ceramic plate, heats up to 500°C.
  • E-G71HSRDM: Round plate (135Ø mm), 20-liter flow rate, aluminum plate, heats up to 380°C.

Applications: Useful in thermosensitive chemistry and biology, heat fixation, pH optimization, solution sterilization, endothermic reactions, organic material denaturation, sample preparation, solution and buffer preparation, and reagent solubilization.

Display: Features a backlit LCD display for temperature, speed, and time, with green indicator lights for heating and shaking phases, and over-temperature alerts. Icons display various smart technologies in use.

Operation and Accessories Included: Includes a mains cable, 20.3 cm (8") stainless steel RTD temperature probe, 3.8 cm (1.5") PTFE-coated stir bar, and protective hood.

Communication: A USB port facilitates programming of repetitive applications, enhancing safety through SmartLink™ technology and long-range user detection via an optional Bluetooth dongle.

Structure: Boasts heat-insulated, chemical-resistant SmartHousing™, IP21 rating, a tempered glass front panel, control knobs, an on/off heater switch, an integrated support rod holder, and easy-to-clean ceramic or aluminum plates.

Construction Features: Includes temperature indicator lights, audible alarms, temperature limit functions, SafetyHeat™ cut-off for malfunctions, calibration for multiple probes, and SmartRate™ features for optimal control.

Why Questpair exists

Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.

We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.

We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.

Frequently asked questions

How long does laboratory equipment typically last?

With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.

Can I get service for older equipment?

Yes. Every verified supplier states which service partners cover the instrument, and we list that alongside the offer.

Where can I buy parts?

Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.

What is the typical lead time for refurbished equipment?

Two to six weeks, depending on refurbishment scope and whether calibration is included.

Does laboratory equipment ship internationally?

We ship to 38 countries. Crating and customs handling are quoted with the instrument.
