The Roundfin RS-3 is a compact, benchtop automated slide stainer designed specifically for H&E staining in histology and pathology laboratories. With a small footprint of just 940*295*340mm (W*D*H) mm and weighing only 28KGS, the RS-3 can be placed directly near the microtome sectioning area for an optimized staining workflow. The instrument processes 24pcs slides simultaneously across 15 (Station 1 is for drying, Station 2 is for washing and other 13 stations are for reagents) with Approximately 350ML reagent capacity per cup, delivering consistent, high-quality H&E staining in a space-efficient format.
Featuring an intuitive touch screen interface with a high-intelligence control system, the RS-3 stores 25 programmable staining protocols (each with 30 editable steps) across 9 user accounts with password-protected protocol security. The intelligent auto water inflow, flush, and drainage system guarantees thorough washing and water efficiency. Processing time is adjustable within Adjustable within 0-59 minutes and within 0-59 seconds per station with customizable dripping time (Adjustable within 0-60s) and stirring frequency (Adjustable within 0-6 times/minute). The APS-coated, streamline-designed housing is corrosion-resistant and easy to clean. The slide rack can stop above or inside the cup after staining with an audible alarm reminder.
