The Eppendorf Piezoxpert is designed for piezo-assisted manipulation or microinjection techniques.
According to Eppendorf, digital programmable parameter setting allows the user to perforate cell membranes with high accuracy and reproducibility, improving productivity and yields for many microinjection procedures in transgenics, developmental biology and other cell biology applications.
The Piezoxpert comprises a control unit, a space-saving piezo actuator and an ergonomic foot control.
Impulses may be triggered either through the foot control or a button on the device, with optical feedback confirming pulse activation.
The number of piezo impulses can be predefined, allowing for gentle and controlled manipulation.
Digital parameter setting is via two rotary knobs and all settings for two channels are displayed at the same time.
The construction and operation principle, with direct transmission of the piezo impulse, is designed to provide enhanced reproducibility for techniques such as mouse ICSI, enucleation and injection of ES cells.
Three program keys on the Piezoxpert give quick access to stored sets of parameters, while a fast and powerful 'clean' function speeds up workflow by removing debris from the capillary.
An automatic self-test is performed each time the device is switched on.
The Piezoxpert is compatible with Eppendorf's micromanipulation systems, including earlier models, as well as products from other manufacturers.
With a 17 x 23 cm footprint, the system is designed to fit beside any micromanipulation workstation.
