The Two Baskets Carousel Type Auto Tissue Processor is a fully automated histopathology instrument designed for routine tissue processing in research and clinical laboratories. This carousel-style processor accommodates dual specimen baskets with sequential processing through 12 reagent stations (9 reagent cups and 3 paraffin cups) with programmable timing from 0-2000 minutes per station. The system incorporates vacuum-assisted reagent exchange, automated basket stirring, and temperature-controlled paraffin infiltration up to 85°C.
The instrument features a 1.3L double basket configuration with 30-second draining cycles and integrated stirring mechanisms that operate for 1 minute every 5 minutes to ensure uniform reagent penetration. Operating temperature range spans room temperature to 70°C, accommodating various processing protocols from routine formalin-fixed paraffin-embedded (FFPE) preparation to specialized staining procedures. The system supports both 220V/50Hz and 110V/60Hz power configurations for global laboratory compatibility.
How It Works
The tissue processor operates on the principle of sequential reagent immersion with controlled timing and agitation. Specimens loaded into the dual basket system undergo systematic progression through 9 reagent stations containing graded alcohols for dehydration, clearing agents, and finally 3 temperature-controlled paraffin baths for infiltration. The carousel mechanism rotates baskets between stations according to programmed protocols, with each station maintaining precise timing control from 0-2000 minutes.
Vacuum assistance during reagent changes ensures complete drainage within 30 seconds, preventing cross-contamination between processing steps. Automated stirring mechanisms activate for 1-minute intervals every 5 minutes throughout the process, promoting uniform reagent penetration and reducing processing artifacts. The paraffin stations maintain temperatures up to 85°C for optimal wax infiltration, while the vacuum pump operates in 5-minute cycles with 1-minute intervals to facilitate reagent exchange.
Temperature control across the system ranges from room temperature to 70°C, accommodating various processing protocols. The programmable timing system allows customization of processing schedules based on specimen type, size, and specific research requirements, ensuring reproducible results across multiple processing runs.

Practical Tips
Verify paraffin station temperatures monthly using a calibrated thermometer and document readings for quality assurance records.
Why: Temperature accuracy directly affects paraffin infiltration quality and subsequent sectioning performance.
Clean reagent stations and baskets thoroughly after each processing cycle, paying particular attention to paraffin residue removal.
Why: Residual reagents and paraffin buildup can affect subsequent processing quality and contaminate specimens.
Monitor reagent levels before starting processing cycles and maintain consistent reagent change schedules based on processing volume.
Why: Depleted or contaminated reagents compromise tissue processing quality and can result in sectioning difficulties.
If baskets fail to advance properly, check vacuum system operation and ensure drainage cycles complete within 30 seconds.
Why: Incomplete drainage prevents proper carousel advancement and can disrupt programmed processing protocols.
Document processing protocols, reagent batch numbers, and processing times for each specimen batch to ensure traceability.
Why: Comprehensive documentation enables troubleshooting of processing issues and supports quality management requirements.
Ensure adequate ventilation around the unit and use appropriate personal protective equipment when handling reagents and specimens.
Why: Tissue processing reagents include hazardous chemicals requiring proper ventilation and safety precautions.
Schedule processing cycles during off-hours to maximize laboratory efficiency and reduce workflow disruption.
Why: Automated processing allows unattended operation, enabling 24-hour laboratory productivity while maintaining consistent results.
Inspect stirring mechanisms regularly and verify proper basket agitation during processing cycles.
Why: Consistent agitation is critical for uniform reagent penetration and preventing processing artifacts in tissue specimens.
