GP Water Baths 1-1Thermo Scientific
Section 1 Introduction
Precision General Purpose Water Baths are designed for a wide variety of
serological research procedures as well as a broad range of other general
laboratory applications. Operation and maintenance of these baths are
covered in this manual; unless specifically noted otherwise, the
information provided applies to all available models.
Precision water baths feature a one-piece, deep-drawn stainless steel
chamber with welded and painted galvanized steel outer body. Depending
on the model, either one or two heaters are attached to the bottom of the
bath chamber. For faster temperature recovery and reduced power
consumption, the baths are equipped with a stainless steel cover (except
Model 2827/2828, which is equipped with a plastic cover). This cover
must be in place to reach and maintain 100°C.
All units (except Model 2823/2824) also feature an adjustable support
shelf which may be set at three different height levels by simply changing
the position of the legs. Model 2823/2824 is equipped with a non-
adjustable diffuser shelf.
As the ultimate user of this apparatus, it is your responsibility to
understand its proper function and operational characteristics. This
operating manual should be thoroughly read and all operators given
adequate training before attempting to place this unit in service. Awareness
of the stated cautions and warnings, and compliance with recommended
operating parameters - together with maintenance requirements - are
important for safe and satisfactory operation. The unit should be used for
its intended application; alterations or modifications will void the
warranty.
Warning As a routine laboratory precaution, always wear safety glasses
when working with this apparatus. s
Caution Model 2847/2848 and 2851/2852 water baths require two
persons to unpack and lift the product to bench height. s
Caution The bench top must be rigid and strong enough to comfortably
support the weight of the unit when filled with water. s
