Eppendorf® EDOS™ Electronic Dispensing System

By Eppendorf
Eppendorf® EDOS™ Electronic Dispensing System

Eppendorf's Model 5222 programmable dispensing system consists of a microprocessor-controlled base unit with LCD display and an attached dispensing handle. The unit accepts Eppendorf Combitip ® Plus tips or adapters for single- or 8-channel pipetting.

The control unit offers programs for routine and specialized applications, including repetitive pipetting of single or multiple volumes, titration, serial dilution, sample mixing and customized dispensing. Adjustable calibration provides greater accuracy with viscous liquids. System stores up to 30 working routines for each mode and the optional EDOS programming package allows additional computer control or data storage potential. Performance data documentation comes with each unit.

The basic EDOS system includes a control unit, dispensing handle and stand, one of each size Combitip Plus and adapter for 50mL Combitip Plus. All single- and 8-channel adapters and Combitip Plus tips also sold separately. Also available are an extension cable and adjustable stand for the dispensing handle and a foot switch control.
