25.3 Definition of usable volume
The usable volume illustrated below is calculated as follows:
c

a
C

A
b
a
A, B, C = internal dimensions (W, H, D)
a, b, c = wall separation
a = 0.1*A
b = 0.1*B
c = 0.1*C
V
USE
= (A - 2 * a) * (B - 2 * b) * (C - 2 * c)
Figure 30: Determination of the usable volume
The technical data refers to the defined usable volume.
Do NOT place samples outside this usable volume.
Do NOT load this volume by more than half to enable sufficient airflow inside the chamber.
Do NOT divide the usable volume into separate parts with large area samples.
Do NOT place samples too close to each other in order to permit circulation between them
and thus obtain a homogenous distribution of temperature, CO
2
, O
2
(chamber with O
2
control)., and humidity.
