OPERATION
L

OADING
AMPLES
The manufacturer strongly recommends waiting at least 8 hours after putting the incubator in
operation before loading samples in the chamber. This safeguards against temperature instability.
Samples should be placed at least 1 inch (25 mm) away from the chamber walls.
Proper spacing allows for maximum air circulation and a higher degree of temperature
uniformity.
Proper spacing also decreases the chance of condensate forming in the incubator when
operating with a large number of samples in the chamber.

HAMBER
CCESSORY
The incubator is provided with four 110 – 120-volt, 1-amp power outlets inside the chamber. Do not
attach powered equipment that draws more than 1 amp.
Verify that any powered accessory equipment used inside the chamber can safely and
effectively operate within your selected temperature range.
Powered equipment, such as stirrers or shakers, can generate heat sufficient to disrupt the
thermal uniformity and stability of the chamber.
H
UMIDIFYING THE
Long-term use of a large water container, such as a humidifier pan, will create excess water vapor
in the unit and can damage the electrical components of the incubator. Additionally, the use of
deionized water may cause significant corrosion damage to the incubator. Overloading the unit
with sample media may also damage the incubator from excessive media evaporation and
disruption of airflow pathways through the shelf space.
Small Sample Load
Placing a small number of Petri dishes or other media containers in the incubator chamber may
lead to excessively fast drying of sample media. A small water-filled container, such as an open
flask, may be placed in the chamber to help slow sample drying with small loads.
