DEPtech 3DEP Reader

A Dielectrophoresis Cell Anaylsis System

The 3DEP system

uses a patented chip design which is low cost, simple to use and allows the analysis of thousands of cells simultaneously.


Low cost disposable chips suitable for a large range of cell types from large myocytes to bacteria.


Applications include cancer diagnostics, monitoring apoptosis, stem-cell differentiation, drug discovery, in-vitro toxicology and many more.
