1 Introduction

1.1 Instrument description

The 807 Dosing Unit is a versatile buret unit which can be operated with a

700 Dosino or 800 Dosino dosing drive. The 807 Dosing Unit is suitable

for precise dosings, titrations, pipetting procedures, sample transfers, etc.

The four inputs and outputs (ports) are designed for flexible use (presum-

ing the presence of a suitable control device).

Thanks to the transparent housing of the 807 Dosing Unit, piston move-

ments and stopcock rotations are visible. This means that even complex

liquid handling applications are easy to monitor. The unobstructed view

into the dosing cylinder also ensures that solutions can be monitored with

respect to the absence of bubbles and the leak-tightness of the cylinder

unit.

Specifications concerning the dosing unit and the reagent can be stored in

the integrated data chip. This data can be extracted and updated by a

suitable control device.

1.2 Model versions

The 807 Dosing Unit is available with cylinder sizes of 2 mL, 5 mL, 10 mL,

20 mL and 50 mL. In addition to glass cylinders, plastic cylinders (ETFE)

specially manufactured for alkali and other aggressive solutions are also

available.
