Reacti-Therm™ I and III
Heating Modules

18822 18824

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.

Safety Information

Reacti-Therm Heating Modules were designed for proper function, reliability and safety. The researcher is responsible for
installation in conformance with local electrical safety codes. This manual contains important safety information. Read this
manual carefully and understand its contents before using this equipment.

A. CE Marking and CSA Certification

The Reacti-Therm Models 18822 and 18824 have been evaluated to comply with CE certification requirements, in
accordance with the following IEC standards, as they apply for use with non-flammable materials only.

• EN/IEC 61010-1:2001

Part 1: General requirements

• EN/IEC 61010-2-010:2005

Part 2-010: Particular requirements for laboratory equipment for the heating of materials

The Reacti-Therm Models 18822 and 18824 have CSA certification per file number 245561.

B. Warnings of Potential Hazards

Reacti-Therm Models 18822 and 18824 (hereafter “equipment” or “unit”) have been designed for safe operation when in
normal use and conditions and operated in accordance with these instructions. The following Warnings
and actions that pose potential hazards to the User(s). The Responsible Body for the equipment must read these Warnings
this entire Instruction Manual and verify that the User(s) are suitably trained before using the equipment.

and

Warnings:

• Always follow good laboratory practices when using this equipment and follow your institution’s safety procedures and

health and safety and associated legislation applicable to your areas of operation. Understand laboratory procedures for
substances being heated to ensure that any hazards (e.g., explosion, implosion or the release of toxic or flammable
concentrations of gases) that might arise have been suitably addressed before using this equipment.

• The equipment is not spark/explosion proof and has not been designed for use in hazardous areas according to the terms

of EN/IEC Code BS5345: Codes of practice for selection, installation, and maintenance of electrical apparatus for use in
potentially explosive atmospheres.

• When heating certain substances, the liberation of hazardous gases may require the use of a fume hood, or other suitable

extraction system, to avoid the accumulation of hazardous concentrations of any gasses. Keep in-block vials of any
potentially hazardous materials closed unless evaporating using the Reacti-Vap Evaporator and inert (nitrogen or argon)
gas flow. Perform small-volume analytical derivatization reactions or vacuum hydrolysis reactions in approved
Reacti-Vial Small Reaction Vials or similar vessels.

• Position and operate the equipment on a clean, dry, non-combustible work surface with at least 16 inches (41 cm) of

clearance from other equipment or materials. Do not position the equipment in a space where it is difficult to disconnect
the power cord at the rear of the unit. Do not allow the power cord to contact hot surfaces of the equipment, accessories
or samples.

• Do not fill or empty sample-containing vial(s) when positioned in the unit to avoid potential spills. Use caution and

appropriate laboratory procedures when handling and transporting heated and non-heated vials and samples. The module
is not designed to retain liquids. If spillage occurs, immediately disconnect main power supply and then remove liquid to
prevent damage to electrical components and to prevent possible fire hazard.

• Do not cover the unit when in use or leave the heating or stirring functions on except when needed for use with samples.

• Do not lean or stretch over equipment. Vials or other objects protruding from the top could be broken or cause injury.

• Allow the unit to cool before cleaning. Always disconnect the power plug from the outlet before attempting any external

cleaning. Use mild soap and water only. Verify that cleaners and decontaminants are compatible with the chemical
properties of relevant samples and are appropriate for the unit and any accessories (e.g., glassware, aluminum blocks,
steel evaporator needles) involved.

Note: If this product is not used in accordance with these Warnings

and this entire Instruction Manual, then the basic safety
protection afforded by the equipment may be compromised. Protection provided by the equipment may be impaired if the
equipment is used with accessories not provided or recommended by the manufacturer, or is used in a manner not specified
by the manufacturer.
