High Performance Incubator 1-1Thermo Scientific
Section 1 Description
Thermo Scientific High Performance Incubators are useful in all types of
general incubating and paraffin imbedding.
Cabinets are made of heavy-gauge steel with a powder-coated finish for
optimum appearance and easy cleaning, while the interior walls are
stainless steel to spread warmwall radiant heat evenly throughout the
chamber. Heaters are in direct contact with chamber walls to allow close
temperature control and quick recovery after door openings. This
arrangement also minimizes temperature gradients and offers a large
working area in the chamber.
A double set of doors, the inner of tempered glass, permits unobstructed
viewing of chamber contents without disturbing the interior environment.
Slide-out shelving can be positioned to meet user requirements.
A PID microprocessor based controller maintains chamber temperature.
An over-temperature safety thermostat controls temperature in the event of
primary control failure. A status lamp above each control is lit when the
respective control is maintaining power to the heaters.
Two grounded 3-prong convenience outlets are installed in models. Models
are built for either 120 VAC or 240 VAC power requirements. Models
PR205075M, PR205070M and PR205070MCN have the same
characteristics as those listed above but, in addition, provide mechanical
convection. These models use a blower and plenum design to circulate the
air within the chamber to allow for rapid temperature and uniformity
recovery after door openings.

Section 2 Safety Information
Your Thermo Scientific High Performance Incubator has been designed
with function, reliability, and safety in mind. It is your responsibility to
install it in conformance with local electrical codes. It is most important
that the user follow installation instructions exactly as written. Failure to
do so is likely to lead to improper operation, erroneous calibrations and
possible damage to the equipment. Do not attempt operation without this
information.
