Overview

All XF instruments analyze mitochondrial respiration and glycolysis in live cells, generating data in just minutes. XF Technology uses solid-state sensors to simultaneously measure both oxygen consumption rate (OCR) and extracellular acidification rate (ECAR) in every well. All platforms support injection of up to 4 unique compounds per well.

XFp Analyzer
XFp
The XFp Analyzer features fast and easy setup using built-in assay templates and a miniplate format, making it ideal for researchers who run just a few samples per day. Key applications include metabolic phenotyping of rare cell types, patient-derived samples, and other precious cells. The XFp Analyzer is our most affordable XF platform and is suitable for performing our gold standard Stress Tests in a pairwise comparison format.
XFe96 Analyzer
XFe96
The XFe96 Analyzer provides the highest capacity for XF assays at the lowest per-sample cost. The XFe96 enables a large number of experimental groups per assay, making it ideal for labs seeking to maximize design flexibility and sample throughput. Recommended for model organisms, screening applications as well as dose-response studies. Can analyze individual spheroids with the XFe96 Spheroid Micoplate. Validated for assays performed in a hypoxia chamber.
XFe24 Analyzer
XFe24
The XFe24 is validated by hundreds of peer-reviewed publications, and utilizes a larger well format which is suitable for fish embryos and other specialty sample types.
