2.2.2 Packing list verification
Unpack your order, saving the packing materials for possible future use. Save the operating manual for
instruction and reference. Verify against your Eppendorf packing list that you have received the correct
materials, and that nothing is missing. If any part of your order was damaged during shipping, is missing,
or fails to operate, fill out the "Customer Feedback" form, available online at http://
newbrunswick.eppendorf.com/.
2.3 Features
The Galaxy 170 R/170 S CO
2
Incubator is microprocessor-controlled and designed to ensure accurate and
reliable operation.
2.3.1 Control system
The incubator incorporates a sophisticated control system that allows for easy programming, control and
monitoring of the chamber conditions.
2.3.2 Direct heating system
A direct heating system, utilizing a thermal heating element, completely surrounds the incubator, providing
an even temperature within the chamber. The independently and directly heated outer door is designed to
ensure an even distribution of heat. This system ensures a rapid, controlled return to optimum chamber
conditions after a door opening while also preventing any overshoot. The incubator’s direct heat system
provides for optimal use of laboratory space by allowing the most efficient internal volume for the footprint
of the instrument.
2.3.3 Infrared sensor
A solid-state infrared sensor is used to control the level of CO
2
, providing excellent reliability, while
remaining unaffected by humidity. The CO
2
system has a programmable automatic zero system (Auto-zero)
to re-reference the sensor baseline to atmospheric CO
2
levels at regular intervals. A small pump supplies
filtered atmospheric gas to the sensor. The chamber atmosphere within the sensor is completely displaced,
allowing the control system to automatically reference the sensor, after which the pump is switched off,
allowing the chamber atmosphere to homogenize back into the sensor. This provides for accurate CO
2
control without disturbing the chamber environment. For programming information (see Temperature and
CO
2
level on p. 32). For Auto-Zero instructions (see PROGRAMMABLE CO
2
AUTOZERO on p. 34).
2.3.4 Controlled humidity tray
A controlled water tray at the bottom of the incubator allows a high, uniform relative humidity (RH) while
preventing condensation in other parts of the chamber. Perforated shelves are provided as standard to
facilitate a much faster recovery of RH conditions in the chamber than with unperforated shelves.
