🔬 Instrument Overview
The BenchMark XT / DISCOVERY XT / BenchMark LT are automated continuous-flow tissue staining systems that perform the precise multi-step IHC and ISH staining processes required for pathological diagnosis of disease from biopsy specimens. The system automates reagent dispensing, temperature-controlled incubation, mixing, and fluid removal across each slide simultaneously — with all operations governed by barcode-driven protocols managed through the integrated NexES software platform.
Key Capacity Differences:
- BenchMark XT / DISCOVERY XT — accommodates up to 30 slides
- BenchMark LT — accommodates up to 20 slides
