Lasers for flow cytometry

Flow cytometers is a bioanalytical tool in which single or multiple cellular properties are determined by analyzing large populations of cells. In a standard configuration the fluorescence labelled cells pass through the laser beam in a hydro-dynamically focused jet stream in a flow cell.

More advanced systems can be used for Fluorescence-Activated Cell Sorting (FACS). Cytometry instruments are commonly used tools in the fields of hematology and immunology, and are used in biomedical research as well as in clinical diagnostics applications.

All Cobolt lasers offer high power, excellent beam quality and low noise, which are important properties in order to maximize resolution and sensitivity (often referred to in terms of a low CV value) of the instruments, and for applications with high throughput requirements.
