The Roche Benchmark GX is a fully automated slide staining system designed for clinical diagnostic laboratories. It is used for immunohistochemistry (IHC) and in situ hybridization (ISH) applications, including SISH (silver in situ hybridization), Dual ISH, and FITC assays. 

Roche Benchmark GX product description: 

Automated Staining: It automates the entire staining process, from baking and deparaffinization to cell conditioning, staining, and counterstaining. This reduces manual steps and human variability, leading to more consistent and reproducible results. 

Flexibility: The system allows for the processing of different assays side-by-side, providing flexibility in the lab's test menu. It can handle IHC, Dual/Triple IHC, ISH, and FITC assays. Users can customize individual incubation times and temperatures for each of the 20 slide positions. 

Efficiency and Throughput: The Benchmark GX is designed to optimize workflow, improve turnaround times, and increase the number of slides processed per hour (up to 40 IHC slides in 8 hours or 20 ISH slides in 8 hours, with an additional 20 slides possible overnight). Automation frees up laboratory personnel for other tasks. 

Quality and Reliability: The system incorporates features like individual slide heaters, liquid coverslips, and air vortex mixing to ensure uniform staining across all slides and maintain tissue integrity. Barcode accuracy helps ensure the right test is performed on the correct patient sample. 

Compact Design: With a small footprint, the BenchMark GX is a space-saving solution for laboratories. 

Reagent Management: It has a 25-position reagent carousel and can accommodate up to seven different bulk reagents, with onboard capacity for up to 60 slides. It also features level-sensing waste disposal. 

Connectivity: Multiple instruments can be controlled from a single PC if needed. 

Key specifications of the Roche Benchmark GX include: 

Slide Capacity: 1 to 20 slides with independent temperature control for each position. 

Reagent Capacity: 25 reagent positions. 

Bulk Reagent Capacity: Up to seven 3-6 liter onboard containers. 

Slide Types: Compatible with 25 x 75 mm, 1 x 3 in, or 26 x 76 mm positively charged slides. 

Temperature Control: 37°C to 95°C ± 2.0°C, and 95°C to 100°C +2°C / -3°C. 

In essence, the Roche Benchmark GX is a valuable tool for pathology laboratories seeking to automate and standardize their IHC and ISH staining processes, improve efficiency, and deliver diagnostic confidence.
