The model CO-150 CO
2
incubator is microprocessor-controlled and designed to ensure
accurate and reliable operation. The unit incorporates a simple, door-mounted touch-
sensitive keypad with two individual three-digit LED displays that allow for easy
programming and monitoring of the chamber conditions.
A direct heat system, utilizing a thermal heating element, completely surrounds the
incubator, providing an even temperature within the chamber. The independently heated
outer door is designed to ensure an even distribution of heat, thereby eliminating
condensation on the inner door. This system ensures a rapid, controlled return to optimum
chamber conditions after a door opening while also preventing any overshoot.
A solid-state infrared sensor is used to control the level of CO
2
, providing excellent
reliability and remaining unaffected by humidity. The CO
2
system has a semi-automatic
zero function (“AutoZero”) that provides a simple process to maintain an accurate level of
CO
2
within the chamber.
The 150-liter chamber and all internal components are manufactured from polished stainless
steel. The non-tip shelves, shelf racks and humidity tray are easily removed without tools for
thorough cleaning and are capable of being sterilized. Air circulation is achieved without the
use of a fan, eliminating ductwork (a potential source of contamination), simplifying
cleaning, eliminating vibration and reducing small sample evaporation within the chamber.
The outer shell of the incubator is manufactured from zinc-plated stove enamelled steel to
give a durable corrosion-resistant finish.
The incubator incorporates a two-level alarm system. The chamber-monitoring alarms are
programmable and will alert you if temperature or CO
2
have not recovered within a preset
time after the door has been opened. If it is not required, this system can be disarmed. The
system alarms occur only if a problem has developed with system components that require
user intervention to rectify. The incubator also incorporates an over-temperature safety
system that operates independently from the main control system.
The incubator’s direct heat system was designed with optimal use of laboratory space in
mind: it allows the most efficient internal volume for the footprint of the instrument. In
addition, the incubator’s top panel is specifically designed to support the weight of a second
identical incubator stacked directly on top of the first.
