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. Heating block inserts for Reacti-Therm Heating/Stirring Modules. Thermo Scientific Reacti-Block Aluminum Blocks are rectangular aluminum block reservoirs designed to hold different sizes and types of vials, test tubes and microcentrifuge tubes for effective sample incubations in Reacti-Therm Heating/Stirring Modules. The blocks are available in two different heights with variety of hole-sizes and configurations to match different types and sizes of vials, including Reacti-Vial Small Sample Vials and test tubes. The blocks are easily interchanged in single-block and triple-block Reacti-Therm Modules, providing for different scales and types of heated sample reactions using one instrument. Reacti-Block Aluminum Blocks. Blocks are available with different numbers, sizes and configuration of well designed to accommodate specific types of vials and other glassware. Reacti-Therm III Heating/Stirring Module. Triple-block module containing three Reacti-Block Aluminum Blocks, several Reacti-Vial Small Reaction Vials and a compatible thermometer. Highlights: Interchangeable – all blocks have same footprint (7.5 x 9.4 cm = 3 x 3.7 inches) and can be placed in either single-block or triple-block Reacti-Therm Heating Modules Uniform, stable heating – constructed of an aluminum alloy for optimal thermal conductivity Thermometer-ready – integrated thermometer well (7.1 mm diameter x 36.5 mm deep) designed for use with Reacti-Therm Thermometer or other standard thermometer Many configurations – hole sizes and configurations available for many types of reaction vessels (see Ordering Information and Related Products section below) Customizable – Reacti-Blocks J and K contain no holes, allowing for custom drilling patterns Evaporator-compatible – several configurations (Reacti-Blocks A1, B1, C1, M1, Q1, S1, T1, V1) have holes that align with ports of Reacti-Vap Evaporators when used with Reacti-Therm Heating/Modules 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-Therm Heating/Stirring Modules Reacti-Therm Thermometers Reacti-Vap Evaporators Reacti-Vial Small Reaction Vials Hypo-Vial Sample Storage Vials Screw Cap Septum Vials Vacuum Hydrolysis Tubes
