Reciprocal Shaking Water Baths

Thermo Scientific
General Information
Precision Reciprocal Shaking Water Baths are ideal for applications needing
constant, controlled agitation and precise temperature uniformity. Two sizes are
available: 14.5 liter (Model 2870/2871) and 26.5 liter (Model 2872/2873).
These instructions are applicable to all models listed in Table 1.
The microprocessor control panel houses all functions necessary to operate the
bath. The five push-button switches and single display window allow the
operator to adjust bath temperature, motor speed, and calibration via a single set
of controls.
The proportional integral derivative temperature control allows precise
temperature control from 5°C above ambient to 55°C without cover and to
99.9°C with use of the gable cover provided.
A high limit thermostat is provided and can be set to prevent heater runaway in
the event of temperature control failure.
Tray shaking speed is easily adjusted between 30 and 200 cycles per minute at 5
cpm intervals. The tray stroke can be adjusted to three different lengths: 0.5", 1"
and 1.5". The drive mechanism contains self-lubricating bearings which require
no maintenance.
