FAQ
How many slides can the RS-5 process per hour?
The RS-5 achieves a maximum throughput of 400 specimens per hour. It supports 10+ staining racks with up to 30 racks processed simultaneously across 36 pcs stations, with 4+ independent programs running in parallel without interference.
What happens if the instrument stops unexpectedly during a staining run?
The RS-5 features fault-stop memory resume. After the issue is resolved, the instrument automatically resumes from the memorized position in the staining protocol, maximizing specimen utilization and preventing the loss of partially processed slides.
How does the robotic arm reduce dye carry-over?
The robotic arm performs three automated functions between reagent stations: shaking to dislodge excess dye, draining to remove residual reagent, and liquid throwing to eliminate droplet carry-over. Combined with the 5 pcs automatic wash tanks, this significantly reduces cross-contamination between staining stations.
Can multiple staining programs run simultaneously?
Yes. The RS-5 supports 4+ programs and 10+ staining racks running simultaneously without mutual interference. The 3-level reagent tank access priority system (Level 3 highest) can be configured to optimize scheduling when multiple programs compete for the same reagent station. Rack status and program progress are displayed in real time on the 10.4 inch 22.5*13.5cm touch screen.
