Herathermä Advanced Protocol Ovens
The series provide bench-top models with 60, 100 or 180 l as well as floor models with 400 or 750 l chamber volume and 3 different fittings, each optionally with gravity or mechanical convection.
-Very high energy efficiency, environmentally friendly materials (reduced use of formaldehyde), reduced heat emission
-Programmable timer
-Small footprint
-Flexible shelf system doubles the number of shelves and therefore the footprint
-Very good spatial and temporal temperature stability
-Automatic visual and acoustic over-temperature alarm
-Very low temperatures at outer wall
-Easy to read vacuum fluorescent display
-Intuitive user interface for setting temperature
-Easy cleaning due to edgeless fabrication
Herathermä General Protocol:
Perfect for routine daily work from 10 to 250 °C. Chambers made from corrosion-resistant st. steel with rounded corners. Timer, mechanical exhaust vent as well as 2 shelves are incl. as standard.
Herathermä Advanced Protocol:
For a greater flexibility and accuracy of temperature values. With V2A st. steel interior, works up to 330 °C at highly stable temperatures. Digital timer for daily or weekly On / OFF cycles. Up to 10 cycles can be stored and combined as ramps. Fan speed and air valve can be integrated into ramp programming. Selectable quick start function allows for extremely fast heating.
Herathermä Advanced Protocol Security:
Additional to equipment of the Advanced Protocol series: under-temperature alarm for improved sample protection. With door lock and door alarm to prevent disruption and allow for safe cultures for a long time. Optional auto-dry function deactivates oven when the samples are dry. The V2A inner chamber can be supplemented by a st. steel outer housing for pharmaceutical and clinical applications.

As well as incorporating all the benefits of Thermo Scientificä Herathermä General Protocol ovens, the Herathermä Advanced Protocol range boasts additional features providing even more flexibility, accuracy and dependability.

-Sophisticated timer extends the automation options available to the user: turn on or off after a pre-set time, choose between a recurring weekly timer or run oven based on the 24 hour clock
-Highest level of temperature uniformity
-Exceptionally low energy consumption - 60 litre models just need 170W (gravity convection) and 275W (mechanical convection) per hour to maintain 150°C
-Adjustable fan speed for application related airflow
-Programmable controller for temperature ramps and dwells (store up to 10 programs with 10 discrete steps, features electronically controlled fan speed and damper position)
-Access port allows the introduction of sensors for independent data monitoring
-A simple calibration routine ensures temperature accuracy over time
-Boost function enables rapid heating up - no need to run the oven 24/7 (tabletop models only)
-Optional stainless steel exterior
