3.5. Placement of samples
To provide proper air circulation and stable conditions within the chamber, it is necessary to adhere to the
following rules:
- the max height of the samples should not exceed 2/3 of the shelf space
- the samples should be placed so that the space between the containers does not exceed 1/3 of the
width and height of the shelf
- samples should be placed with equal spacing between each other and the chamber walls
The picture below is an example of the placement of samples in the chamber.

Following the above rules will provide optimal parameters of temperature stability and uniformity.
3.6. Closing the chamber door
To close the door, turn the handle to the vertical position, push the door gently then turn the handle to the
horizontal position. If the door has not been closed properly, an alarm will sound. Closing the door correctly
reduces energy consumption and ensures consistent temperature stability and uniformity.
