Labcyte Echo 555 - Echo Liquid Handler Features

Introduction 1-5
1.2 What are the Echo liquid handler features?
Echo liquid handlers are well suited to transferring low-nanoliter volumes of
aqueous and DMSO-based solutions for a wide variety of applications. Echo
liquid handler features that will be important to any organization include:
1.2.1 “Touchless” fluid transfers
Echo technology uses “touchless” fluid transfer.
 Nothing physically touches the fluid in the wells or the interior walls
of the microplate. Droplets are ejected using an ultrasound wave
transmitted from below the source microplate. The ejected droplet is
directly transferred upward from the supply plate to the receiver.
 No direct contact of the source fluid or the ejected droplet as it travels
to the destination plate, means no cross-contamination can occur.
“Touchless” fluid transfer provides the following benefits:
 Improved reliability
 Lower maintenance requirements
 Lower transfer costs
 Reduced waste
The following figure shows a single droplet ejected from a 384-well
microplate. Droplets are discrete and of consistent size without the creation
of spray or aerosol.
