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.

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.

1.1 Front Display
The instrument is operated using three touch-sensitive keys
located below the display (Figure 1). The function of the key
depends on the display. If no function is shown for a specific key,
that key is not currently active.
The actual temperatures of the heating blocks and the remaining
time are visible in the display while temperature programs are
active.

Section 2 Instrument Use
2.1 Starting-up
DANGER
The ventilation slits
in the lid must not be
covered, or
overheating may
occur.
1. Place the instrument on a stable, level, heat-resistant
surface.
2. Plug in the power cord into a power socket (100–230 V
+5%/–15%, 50/60 Hz).
3. Switch on the instrument by switching the power switch
(Figure 4).
4. After initialization, the instrument will beep once, indicating
that it is ready for operation. The display always shows the
most recent setting of the temperature programs after
initialization.

5. Place the vials in the appropriate heating block and close the
protective lid.
6. Start the program using the left key.
7. The time automatically counts down to zero (0). The actual
temperature and the remaining time are visible on the
display.
8. The instrument will beep three times to indicate the
temperature program is complete. It will turn off the heater
and cool.
During operation, the display will indicate the status of the
thermometer.
2.3 Using the Reducing Adapters
If using 16 mm tubes (COD, TNT, etc.) with a heating block with
20 mm diameter holes, insert the reducing adapters into the holes
to reduce the diameter to fit the 16 mm tubes.
2.4 Selecting the Program
The temperature programs can be selected independently for the
right and left heating blocks. If a change of setting is selected, the
user is prompted to specify whether the change concerns the right
or left heating block. Six permanently programmed temperature
programs are available (Table 3). Use the touch-sensitive keys to
select the appropriate temperature program.

Program Description
COD Program
Heats vials for 2 hours at 150 °C. In the cooling phase, 4 beeps
indicates that the vials have cooled to 120 °C. Remove and
carefully invert the vials several times, before allowing them to
cool further in a rack.
TOC Program
Heats the vials for 2 hours at 105 °C. This setting is suitable for
all Hach TOC vial tests.
100 °C Program
Heats vials for 30, 60, or 120 minutes at 100 °C. For example,
the “100 °C, 60 minutes” setting is needed to digest samples
using the Methods Prep Set.
105 °C Program
Heats vials for 30, 60, or 120 minutes at 105 °C.
150 °C Program
Heats vials for 30, 60, or 120 minutes at 150 °C.
