Abstract

A modular laboratory apparatus for analysis and synthesis of liquids has a liquid tank, a central electronic evaluation unit, a multitude of functional modules, and a multitude of fluid modules. The functional modules and the fluid modules are mechanically connected in rows and are selectively connected to each other electrically and fluidically. At least one fluid module is fluidically connected to the liquid tank, and provision is made for electrical connections which connect the functional modules and the fluid modules to the central electronic evaluation unit. In a method for analysis and synthesis of liquids using a modular laboratory apparatus, the functional modules and the fluid modules are controlled by the central electronic evaluation unit by executing an analysis and/or synthesis program in order to perform an analysis procedure and/or a synthesis procedure.
