Features & Benefits

Dimension EXL with LM Integrated Chemistry System - Features & Benefits

  “The Dimension® EXL™ system with the LOCI® module helps us contribute to better patient care because it’s faster and more accurate... I feel very confident about the results that we send out. I trust the instrument explicitly.”
Donna Hartsell, MT (ASCP)
Section Head of Chemistry, Caldwell Memorial Hospital

True Integration for Increased Efficiency

  • Extend capabilities with a comprehensive menu, including chemistry, cardiac, thyroid, and our no-pretreatment immunosuppressive drug assays.
  • Avoid splitting samples—simultaneously run all assays from one sample tube.
  • Simplify your workflow—mix and match chemistry and immunoassay tests in one common reagent area.

"The comprehensive menu allows us to look at the parameters of whole disease states from a single primary tube. That’s the purpose of having just that one instrument to do everything."
Donna Hartsell, MT (ASCP)
Section Head of Chemistry, Caldwell Memorial Hospital

LOCI Technology Inside

  • Experience excellent immunoassay sensitivity using small sample volumes with homogeneous LOCI® Advanced Chemiluminescence Technology.
  • Produce fast and accurate results in 11–18 minutes for key critical assays.

High Productivity

  • Meet workload demands with throughput of up to 627 tests/hour and electrolyte results in under a minute.
  • Increase testing capabilities with 91 assays onboard and the ability to load 18 reagents at once without pausing the system.
  • Respond quickly with STAT sampling from any position and a 4-minute time to first result for a basic panel.
  • Save time with no manual sample pretreatment, no manual reagent preparation, and long calibration stability.
  • Further simplify laboratory operations with connectivity to Siemens automation and IT solutions.


“We were looking for the complete package: one tube, one sample, broad menu, walkaway time, assay quality, backup capability, ease of use, technical service, and fiscal economy.” Jay Bosch
Medical Laboratory Technician, Beaver Dam Reference Laboratory
