Number Description
18822 Reacti-Therm I Heating Module (single block)
18824 Reacti-Therm III Heating Module (triple block)
Introduction
The Thermo Scientific
®
Reacti-Therm Modules are easy-to-use dry-block heaters that provide constant temperature control
(see Table 1 for specifications). They are ideal for heating and evaporation required for sample preparation before analysis by
gas chromatography, high-performance liquid chromatography and other methods. Designed with a recessed cavity that holds
interchangeable Reacti-Block™ Aluminum Blocks, the modules can also be used for routine sample incubation when
elevated temperature control is required.
