Ergonomics? For a Freezer?

For sure, the total weight of a ULT freezer is far less important for you as an user compared to a pipette (whereas it might be of interest floor stability-wise). Ergonomics is far more than just the weight of an instrument. There are several aspects which result in an ergonomic lab instrument: Starting with an ergonomic design of the product itself (e.g. smooth shape, low weight, low forces needed, intuitive user interface,…), fitting into an ergonomic work space and finally supporting an optimal workflow within the lab.
In principle, the ergonomic value of an instrument already starts at the development of a product. This can be achieved by proven concepts and many testings internally as well as with customers.
The R&D team needs to know and to understand the needs within the workflows for optimization of the product.
Regarding the ULT freezers, there are quite some ergonomic aspects besides the weight:
Your major interaction point with a ULT freezer is the door handle. This handle at the outer door should be easy to use: The closing mechanism of the ULT freezer must be strong enough to tighten the outer door for highest sample security. On the other side, the handling force needs to be low enough that every member of the lab team is able to open and close the freezer door.

The display should be at eye level for easy reading of all settings. The display should neither be above the outer door nor below the outer door: Reading the display while being on your tiptoes or kneeing on the floor is not comfortable.
Especially when having a touch-display, this display should have an easy-to-handle interface. The content and structure should be self-explaining without the need to read the operating manual at every step.

Therefore, the noise level has the higher impact the nearer you work at the freezer.
For a quick and comfortable connection of the freezer with power, data, and BMS (Building Management System), a smart collection of all cable interfaces at one location of the instrument is recommended.

The air filter should be accessible in an easy way by removing some quick fasteners or flip down an access panel.
Summarizing, there are indeed some aspects when selecting a freezer which have an impact on your convenience when using these instruments on a daily basis.
