Heratherm Advanced Protocol Ovens
by Thermo Scientific

Terra Universal offers Thermo Scientific Heratherm Advanced Protocol Ovens

Provides the highest level of temperature uniformity

Heratherm Advanced Protocol ovens incorporate all the benefits of the General Protocol Ovens plus added features for superior temperature uniformity, stability and accuracy. With outstanding temperature performance, a corrosion-resistant surface and a corrosion-resistant, stainless-steel inner chamber, these ovens meet the demanding requirements in clinical and pharmaceutical labs.
  • Gravity and Mechanical Convection models are available in coated steel exterior or stainless steel exterior
  • Ideal for applications requiring superior temperature accuracy and increased heating capability of up to 330°C
  • Timer extends operational options and user can either program a recurring weekly timer or program the oven to turn on or off at designated times
  • Low energy consumption for 60 liter models: 170W usage (gravity convection) and 259W usage (mechanical convection) per hour to maintain 150°C
  • Faster heat-up and drying processes
  • Stores up to 10 programs (can be repeated) and up to 10 steps within each program
  • Application flexibility with 2-speed fan (for large capacity models)
    • Slow speed—minimal airflow (e.g. drying of powders)
    • High speed—faster drying and heating; better temperature stability and uniformity
  • Auto-dry function saves energy by turning oven off when samples are dry (need optional temperature sensor to use this feature)
  • Door alarm notifies user when door is left open (for large capacity models)
  • Optional independent sample sensor shows exact sample temperature (sample sensor is optional)
  • Controller can be programmed for temperature ramps and dwells
  • Compact footprint/volume ratio, saves energy; benchtop units are stackable
  • Temperature accuracy over time ensured by simple calibration routine
  • Boost function on benchtop models speeds up heating process and eliminates the need to operate oven 24/7 (feature not available in large capacity units)
  • 180° door opening allows for easy access of samples and easy cleaning
  • Access ports can be used to connect sensors for independent data monitoring
  • Large fluorescent display for clear viewing
  • Easy to use microprocessor-based touch button controls
  • Automatic over temperature alarm system protects samples
  • Option to use exhaust vent as access port for external temperature sensor
  • Easy to clean smooth inner casing with rounded corners
  • Two-Year Manufacturer Parts and Service Warranty

Gravity vs. Mechanical Convection
Gravity convection involves gentle drying and heating with low air turbulences ideal for working with materials that are sensitive to airflow such as powders and foils. These units protect delicate samples while offering temperature uniformity of +/-4°C with temperature stability of +/-0.4°C at 150°C.

Mechanical convection is suitable for faster sample drying and heating with superior temperature uniformity of +/-3.3°C with a temperature stability of +/-0.3°CC at 150°C.
