5. Allow at least 30 minutes for the temperature of the Reacti-Therm™ Heating Module to equilibrate. Actual times
required for the unit to reach equilibrium for a given temperature may vary depending on the block used, room
temperature, etc.
6. Place vials or test tubes containing samples in the heating block.
7. An inert atmosphere can be maintained over samples by using the Reacti-Vap™ Evaporator manifold system, which
provides a flow of an inert gas over samples. See your Pierce Catalog and Handbook for more information.
Safety Tips
1. Allow the unit to cool before cleaning. Unplug the instrument from the 120 volt outlet and remove the heating block
from the well. Keep the block and well clean for future use. To extend the life of the unit, flip the power switch to "off"
when the unit is not in use.
2. The well is not designed to retain liquids. If spillage occurs, liquid should be removed from the well immediately to
prevent damage to electrical components and prevent any possible fire hazard.
3. There is a set of fuses in the power entry module. These will blow if high amperage is applied to the circuit. These fuses
will need to be replaced. If this occurs, an inspection should be made by a qualified service person.
4. Corrosive atmospheres should be avoided to prolong the life of the instrument.
Service and Maintenance
The Reacti-Therm™ Heating Module is relatively service-free. If your module should need maintenance or a replacement
part, contact Pierce. Always disconnect the power plug from the 120 volt outlet before attempting any kind of external
cleaning. Only cleaners that will not harm ferrous or aluminum metal should be used to clean this unit.
Reacti-Therm™ Heating Module Calibration
Equipment Needed:
1 flat-bladed 3 mm tip, 4 1/2” shaft screwdriver
1 Thermometer (Pierce Product No. 18911), Range 0-200°C, 1°C graduations, 225 mm length, immersion depth 35 mm
By adjusting a high trimpot and low trimpot, the temperature of the heating block can be adjusted for the high and low
settings of the heat control knob. Access to the trimpots is through the holes on the right-hand side of the Reacti-Therm™
Heating Module case. Adjusting the trimpots clockwise lowers the temperature and adjusting them counterclockwise
increases the temperature. Allow the temperature of the heating block to equilibrate for 45 minutes after the unit is turned on
and following each additional adjustment.
