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
