Eppendorf EDOS 5221 Electronic Dispensing Pipetting System Controller Only

The Eppendorf EDOS 5221 (Electronic Dispensing and Operating System) is a legacy microprocessor-controlled base unit designed to provide high-precision automation for liquid handling. This specific model is the controller only, meaning it requires an attached dispensing handle and specific syringes (Combitips) to function as a complete system.

Core Functionality

The EDOS 5221 acts as the "brain" of the pipetting system, allowing users to program complex liquid handling protocols that are difficult to achieve with manual pipettes.

• Operating Modes: Supports multiple modes including serial dispensing (multiple aliquots from one aspiration), titration, and reverse pipetting.
• User Interface: Features a clear LCD layout and easy-to-follow menus for individual program storage and execution.
• Precision Control: Controls the motor drive in the handle to ensure high accuracy and reproducibility, especially for repetitive tasks or viscous liquids.

Used; Tested to be in great condition. Does not include power cord or pipettor.
