injury or damage to the instrument could occur if not observed.

This symbol, if noted on the instrument, references the

instruction manual for operational and/or safety

information.

Safety Precautions

Hot Surfaces. Touching the reactor block surfaces and vials

while hot can cause serious burns.

Protective Earth Ground. This product requires a protective

earth connection. If not provided with a plug on a cord,

connect positive earth to this terminal (U.S. cord set

provides ground).

Safety Precautions

Safety Equipment

Use protective clothing when operating the reactor, including

goggles or face mask, and gloves.

Reagent Spills

Clean up spilled reagents immediately. If reagent contacts skin,

rinse the affected area thoroughly with water. Avoid breathing

released vapors. Read the Material Safety Data Sheets (MSDS)

supplied with each reagent for complete chemical information.

Fire Hazard

Avoid the presence of flammable liquids near the operating

reactor. A fire hazard could be created.

Power Cord

A power cord suitable for 115 V ac line voltage is supplied with

the DRB 200.

Section 1 Introduction

The DRB 200 is supplied as two models, with either one or two

heating blocks (Figure 1). The heating blocks can heat solutions

in round vials of various sizes at 37–165 °C for a period of 0–480

minutes. The small, 16 mm diameter openings on the heating

block are suitable for Hach COD, Unicell, TOC, and Test N’

Tube tests. The larger, 20 mm diameter openings are intended for

sample preparation reaction vessels, using the Metals Prep Set.

The DRB 200 has 6 stored and 3 programmable temperature

programs.
