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.
