M Series

It would be a bold new statement for your laboratory.


Deep Freezer Like No Other

The M Series by ARA is a collection of Deep Freezers for storing samples down to minus 95°C varying in different sizes and features. Aside from its industry leading design and build quality, features like DualBrain™ and Independent Dual Compressors, make each unit virtually impossible to fail. 


Touch Screen with DualBrain™

All M series come standard with an easy to use touch screen user interface with legible graphical data displayed all times. Behind the bold casing hides the DualBrain™ system, that has two independent control boards working as an emergency backup system for each other. 



With an option of Secure-AutoDoor™, opening and closing of the pressure locked door is as easy as pressing a button. Not only this works as a convenience feature, but it also works as a way to control the access to the unit. With different user access codes, the admin can limit, track, and record all user activities.
