W8 Physical Cytometer System
Analyzer for sphere-like 3D cell models
The W8 is a flow-based system able to simultaneously measure weight, mass density and size of sphere-like biological samples. The physical characterization is based on the gravimetric method of a microfluidic technology with an image based analysis.

W8 Physical Cytometer System – Quantitative measurement of size, weight and mass density for spherical biological samples
The W8 physical cytometer is a fully automated instrument for the physical characterization of 3D sphere-like biological samples. It covers the range from 50μm sized small clusters up to larger spheroids or organoids with 500μm in diameter. The combination of a microfluidic technology with bright-field image-based analysis provides information about mass density, weight and size of the structure, in just few minutes.
In Addition, sorting of a target sub-population can be operated based on pre-selected parameters, and can be used for further analysis. Flowrate and microchannel geometries are designed to avoid any shear stress on the 3D samples. Its small size and easy handling allow the operator to place the instrument under the biological safety cabinet, when working with live 3D samples. The instrument analyses the samples fully automated.
