  • Extended automation options with timer for energy efficiency
  • Automates oven with pre-set on or off times
  • Low energy usage: 60 L models need just 170 W (gravity convection) and 275 W (mechanical convection) per hour to maintain 150 °C
  • Energy-efficient models with boost function for rapid heat-up eliminates 24/7 run of oven
  • Applications: research, clinical or industrial
  • Stackable benchtop models require optional stacking kit
  • Microprocessor-based touch button controls
  • Large, easy to view vacuum fluorescent display
  • Easy calibration routine for temperature accuracy
  • Electronically controlled fresh air damper vents the work space; equipped with an external slider rotary button control
  • Data logging: access port for independent data monitoring for external temperature sensor
  • RS232 interface, built-in timer, On/off timer functions
  • Sample protection with automatic over-temperature alarm system
  • Dry alarm contact connects to alarm device
  • Doors open at over 180° for easy access

Additional Features

  • 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
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.
  • Provides temperature stability of at least±0.3°C at 150°C and temperature uniformity of±2.9°C or better
  • Low turbulence gentle heating and drying of material sensitive to airflow
  • Ideal for gentle drying applications: electronics, pharmaceutical preparations, soil, sand, powders, paper and textile
  • Ideal for curing paint adhesives, plastics and metals; vulcanization of rubber; heated storage of pills and drugs
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.
  • Provides temperature stability of at least±0.2°C at 150°C and temperature uniformity of±3.0°C or better
  • Ideal for drying of powders and other application-related airflow with adjustable fan speed
  • Delivers optimal temperature distribution
  • Quick drying of glassware, powders, paper and textile
  • Fast temperature recovery after door is opened
Controller Programmable Microprocessor control with vacuum flourescent display
Material Corrosion-resistant stainless steel (AISI 304) inner chamber
Timer On / Off, Recurring weekly, or real time
Temperature Range
  • 50° to 330°C (60, 100, 180L)
  • Ambient +10° to 250°C (400, 750L)
Max Shelf Load
  • 25kg (55 lbs.) (60, 100, 180L)
  • 40kg (88 lbs.) (750L)

Adjustable Fan

Models feature an adjustable fan with five speed settings for application related airflow ideal for drying of powders, paper, food, or pharmaceutical samples
