2.3.5 Seamless chamber
The 170-liter chamber is seamless, to provide a sanitary and easy-to-clean environment, and all internal
components are manufactured from polished stainless steel. The shelves (which are non-tip), 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 duct work (a potential source of
contamination), simplifying cleaning, eliminating vibration, and facilitating use of microplates and
low-volume culture.
2.3.6 Standard features
The Galaxy 170 R/170 S contain many standard features usually seen as options. It has a sealed inner glass
door with a cam action lock to allow viewing of the cultures without compromising the internal atmosphere.
This is also available as a split 4- or 8-inner-door option (to coordinate with shelves), which is ideal for
critical hypoxic studies. In addition, there is a 25
mm (1 in) access port now standard to allow for seamless
integration of independent probes or other equipment through the chamber.
2.3.7 Multiple options
The incubator features multiple options that can be installed to simplify maintenance and provide superior
control over experimental conditions. For example, high-temperature disinfection quickly and conveniently
disinfects the incubator’s chamber at 120
°C, without the need to remove interior components or the CO
2
sensor. A humidity alert and monitoring package display relative humidity levels in the chamber on the
display and warns the user before the humidity tray runs out of water, preventing dehydration of samples.
Oxygen control provides for conditions that require above- or below-ambient oxygen levels. These and
other options and accessories provide for a uniquely flexible CO
2
incubator capable of meeting the most
demanding requirements. For details on equipment options (see Equipment options on p. 65).
2.3.8 Two-level alarm system
The incubator incorporates a two-level alarm system. The system alarms occur only if a problem develops
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.
2.4 Stacking devices
The incubator is designed so that one incubator can be safely stacked on top of either another Galaxy 170 R
or a Galaxy 170 S using the optional stacking kit, which includes instructions. It is not possible to put any
other type of incubator or heavy apparatus on top, as the top cover and stacking kit are designed to support
only the feet of another Galaxy 170 incubator. For installation instructions (see
Stacking stand installation on
p. 93).
