Precisionâ Instruction Manual
General information
These instructions encompass General Purpose Water Baths (see chart below), but the opera-
tion and maintenance of each are similar. The General Purpose Baths are ideal for a wide variety of serological research
procedures and a broad range of other general laboratory applications.
Precision water baths feature a one piece, deep-drawn stainless steel chamber, welded and painted stainless steel outer
body. The model 181 comes equipped with a plastic cover, all others models are equipped with a stainless steel cover to
provide faster temperature recovery and reduced power consumption.
The support shelf, provided with each model from 181 and above is adjustable to three varying height levels by simply
changing the position of the legs. The Model 180 is equipped with a non-adjustable diffuser shelf.
Depending on the model, one (1), or two (2), heaters are attached to the bottom of the bath chamber.
The following water bath capacities were measured with water levels approximately 1-1/2" from chamber top; 1/2" from
chamber top for Model 180.
