Product Details

Advanced Protocol Security ovens incorporate all the benefits of the Advanced Protocol ovens with an extra layer of security for applications where process reliability and security are paramount. Mechanical Convection allows for fast sample drying and heating, superior temperature uniformity, and fast temperature recovery after door openings.

Stainless Steel Exterior provides a robust and corrosion-resistant surface, is easy to clean, and meets demanding needs in pharmaceutical and clinical laboratories

Auto-dry function deactivates oven when the samples are dry, saving energy (Note: An optional sample sensor is required to utilize this feature, see accessories below)

Standard overtemperature alarm and an additional undertemperature alarm ensure that your samples are kept at the correct temperature (alarms are audible and visual)

An audible door alarm notifies the operator when the door is left open accidently

A lockable door provides restricted sample access, prevents disruption, tampering, and accidental opening

Adjustable fan speed for application related airflow: High Speed for fastest drying and heating, quick recovery as well as best temperature stability and uniformity, and Reduced Speed for applications that require minimal airflow, like drying of powders.

Programmable controller for temperature ramps and dwells allows you to store up to 10 programs with 10 discrete steps

Sophisticated timer can automate the oven to turn on or off after a pre-set time and allows you to choose between a recurring weekly timer or a run based on the 24 hour clock

Inner chamber is made from corrosion-resistant stainless steel (AISI 304) with rounded corners for easy cleaning

Door can be opened 180° to allow convenient access to the interior for hassle free cleaning and easy loading of probes

Simple, microprocessor-based touch button controls

RS232 data interface included

Fresh Air damper provides control over air exchanges and is electronically controlled

Dedicated access port allows the introduction of sensors for independent data monitoring

Dry alarm contact included for the connection of an alarm device

Boost function enables rapid heating up – no need to run the oven 24/7

A simple calibration routine ensures temperature accuracy over time

Stackable with an optional stacking kit

Heratherm ovens feature an environmentally friendly design with cost savings in mind, reducing energy consumption by as much as 20% compared to previous (Lindberg Blue M and Precision) models.

Surpassing energy efficiency, increasing cost effectiveness, reducing environmental impact.

Exceptionally low energy consumption

Unique door design reduces heat emission significantly

Timer for effective usage and additional energy savings

Designed with a very small footprint ratio compared to the interior volume

Flexible shelving system allows for optimal space utilization

Routine check upon startup for optimum performance levels

Low surface temperatures

Large, easy to view vacuum fluorescent display

Easy setting with intuitive interface

Easy cleaning with rounded corners
