The Pierce GC Derivatization Reagents, Solvents, Reacti-Therm Products, Vials and Closures are now sold as part of the Thermo Scientific GC Consumable Product Range. Beginning in January of 2010, this page will redirect you to GC Reagents on Thermo.com. Dry block heating units for GC and HPLC derivatization reactions. Thermo Scientific Reacti-Therm Modules are reliable and easy-to-use dry block heater that provide constant temperature control (ambient plus 10°C to 200°C) for test tubes, vials and glassware of various sizes. The modules are ideal for performing heating, stirring and evaporating functions that are required for sample derivatization before analysis by gas chromatography (GC), high-performance liquid chromatography (HPLC) and other applications. The four models of Reacti-Therm Units have a modular design with interchangeable accessories that enable adaptation to a variety of vial types and sizes, heating, stirring and evaporating needs. Reacti-Therm I Heating/Stirring Module (Single Block) Reacti-Therm III Heating/Stirring Module (Triple Block) Each of the two sizes of Reacti-Therm Modules contain a generalized recessed cavity that holds one or three interchangeable Reacti-Block Aluminum Blocks, which provide different formats (number and size) of wells to accommodate a variety of Reacti-Vial Small Reaction Vials, test tubes and other glassware. Two models of Reacti-Therm Modules have stirring function capability when Reacti-Vial Magnetic Stirrers (magnetic stir bars) are inserted into each Reacti-Vial Small Reaction Vial placed in the appropriate aluminum block. Sample evaporation is possible if a corresponding Reacti-Vap Evaporator is attached to the Reacti-Therm Module; when connected to a supply of nitrogen or argon gas, the evaporator manifold ensures accurate flow of gas onto vials placed in the aluminum block.   Reacti-Therm III Module equipped with three Reacti-Block Aluminum Blocks, three Reacti-Vial Small Reaction Vials and a thermometer.   Reacti-Therm III Module equipped with Reacti-Vap III Evaporator (27-port). Highlights: Four models – single-block and triple-block sizes with either heat-only or heat-and-stir capability Uniform, stable heating – steady temperature incubation between ambient plus 10°C to 200°C LED display – match digital display to in-block thermometer to calibrate temperature set-point Modular design – switch aluminum blocks and vials; attach compatible evaporator manifold Dual-voltage flexibility – compatible with 120V and 240 V power; country-specific power cord supplied In-block temperature control option – Remote Temperature Probe (Prod. # 18820) is an optional accessory that allows temperature regulation from block wells or actual sample vials Applications: General sample incubation and evaporation in a variety of tube and vial sizes Silylation, alkylation and acylation derivatization reactions for GC sample preparation Protein hydrolysis and vacuum hydrolysis reactions for amino acid analysis by HPLC Related Products Reacti-Block Aluminum Blocks (required accessory) Reacti-Vap Evaporators Reacti-Vial Small Reaction Vials Reacti-Therm Thermometers Vacuum Hydrolysis Tubes Derivatization Reagents
