Personal 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.
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

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.
DANGER:
Do not allow the power cord to pass under the instrument.

Section 1 Introduction
The DRB 200 is supplied as two models, with either one or
two heating blocks (
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.
