This maxim defines the new OPUS® digital motor-supported burette with its clear, integrative product design. The functional elements are logically interlinked. The compact design has smooth, hygienic surfaces to facilitate cleaning, and extreme technological complexity is reduced to provide a user-friendly, simplified, ergonomic and operationally-reliable product. It therefore represents a correlation of formal and functional characteristics with the proven virtues of Hirschmann laboratory instruments. The control unit also contributes to this, as it can be uncoupled from the basic unit and freely positioned. The touch screen interface enables intuitive control. The non-slip support connects the basic unit (which can be mounted directly on the reagent bottle) and control to form a functionally-reliable unit.
