Powerful advantages
for leading edge applications

Designed With Advanced Users In Mind

Users need flexible analysis capabilities in a flow cytometer. The EPICS XL is designed to give users a wide range of choices in advanced applications. In addition to its 4-color capability, the XL can acquire up to 12 parameters simultaneously from a total choice of 21. Users can create and store their own protocols and panels for their particular applications.

For research requiring sample handling flexibility, the XL offers two modes

of sampling: the MCL Autoloader for large workloads and hands-off sampling; and the Single Tube loader for greater sample interaction and manual control.

Digital Processing For Superior Linearity

For assays requiring fluorescence quantitation, the XL has replaced log amplifiers with digital log transformation for ultra-linear and reproducible results. And since the XL is the first instrument without log amplifiers, instrument-to-instrument reproducibility is unsurpassed.

The XL uses a unique optotransputer board with a fiber optic cable for high speed data transmission. Transputers are also used for instrument control, linear to log transformation and digital compensation.

Percent Error as a function of log value

The XL's digital log transformation yields clearly superior results. (Courtesy of R.E. Auer, Coulter Corp., presented at ISAC XVII, Lake Placid, NY).

PC Compatibility For Effective Use Of The Latest Hardware And Software

The EPICS XL uses the industry standard IBM® PC-compatible computers for acquisition and data analysis. This offers users tremendous advantages because it makes available the latest processors, monitors and other computer peripherals as they are developed.

An SQL database standard is provided for custom reports and the inclusion of additional experimental information. The XL also offers optional network packages and automated data archival for multi-workstation and multi-user facilities. Third party network packages can be obtained to connect PC's with other off-line workstations including Mac PC's. In addition, there are a number of third party flow cytometry software packages available for a variety of leading edge applications.
