Product Overview
The Roundfin RD-500 is a carousel-type automatic tissue processor designed for histology and pathology laboratories requiring reliable, programmable tissue dehydration, clearing, and paraffin infiltration. Featuring a 12-cup carousel design (9 reagent cups + 3 paraffin cups) with 1.3 (2.3L optional)L capacity per cup (2.3L optional), the RD-500 delivers consistent, high-quality tissue processing for routine diagnostic and research applications.
The RD-500 is equipped with automatic cylinder-changing at designated positions, a basket with built-in rotation (every 5 minutes) for thorough reagent mixing and complete reactions, 10 built-in programs supporting 12 processing steps with adjustable immersion times from 0-2000 minutes per cup, and a delayed start function that can schedule operations up to 1 month in advance. Dual safety limiters (internal software + external mechanical) and an obstacle detection sensor protect both the instrument and tissue samples. CE and ISO 13485 certified with 1 year and whole lifetime technical support.

RD-501 Vacuum Model (Also Available)
Roundfin also offers the RD-501 vacuum model based on the same carousel platform, adding a -60kpa (Optional:-70KPA/-55KPA) vacuum function with programmable vacuum pump cycles (5 times/min, 60sec for each time) for enhanced reagent infiltration in dense or fatty tissue specimens. All other specifications are identical to the RD-500 standard model. Contact our team for vacuum model pricing and availability.
Key Features
Automatic Cylinder Change -- Equipped with automatic cylinder-changing function at designated positions. During cylinder change, a 5-second draining period at the top prevents reagent carryover and cross-contamination between processing stations.
Basket Rotation & Stirring -- Sample basket features built-in rotation (every 5 minutes) for thorough reagent mixing and complete tissue reactions. Stirring frequency: 5 times/min, 60sec for each time.
Aluminum Reagent Cylinders -- Lightweight aluminum cylinders with handles are safer and easier to handle than glass alternatives. Glass cylinders also available as an option.
Dual Safety Limiters -- Internal software limiter plus external mechanical limiter prevent component damage in the event of system malfunctions. Obstacle detection sensor stops operation immediately when unmelted paraffin or foreign objects are detected.
10 Built-in Programs -- Store and recall up to 10 program sets with 12 processing steps each. Individual immersion times adjustable from 0-2,000 minutes per cup (minimum 1-minute intervals).
Power-Off Protection -- In the event of a power interruption, the RD-500 resumes operation from the last memory position after power recovery, preventing sample loss during unattended overnight processing.
Delayed Start Function -- Schedule operations up to 1 month in advance. Program tissue processing to begin at any time that fits your laboratory workflow -- start processing overnight for morning embedding, or over weekends for Monday morning readiness.
Manual / Automatic Mode -- Switchable between manual and fully automatic operation modes to suit any laboratory workflow or operator preference.
Application Scenarios
| Scenario | How It Supports |
|---|---|
| Hospital Histology Lab | 10 programmable protocols for standardized diagnostic processing. Delayed start for overnight operation. Power-off protection ensures no sample loss during unattended runs. |
| Research Institute | 12-step processing with up to 2,000 min immersion per cup for extended protocols. Basket stirring ensures uniform reactions for reproducible research results. |
| Veterinary Pathology | Carousel design processes varied animal tissue types. 1.3 (2.3L optional)L or 2.3L cup capacity for flexible throughput. Manual/automatic switching for staffing flexibility. |
| Medical University / Teaching Hospital | 10 stored programs allow standardized student training. Obstacle detection and dual safety limiters prevent instrument damage during teaching sessions. |
FAQ
How many cups and what capacity does the RD-500 have?
The RD-500 features a 12-cup carousel design: 9 reagent cups (1.3L each, 2.3L optional) and 3 paraffin cups (1L each, 1.8L optional). Processing capacity is 50 cassettes per basket at 1.3L, or 80 cassettes at 2.3L.
What is the difference between RD-500 and RD-501?
The RD-500 is the standard atmospheric-pressure model. The RD-501 adds a vacuum function (-60kpa (Optional:-70KPA/-55KPA)) with programmable vacuum cycles (5 times/min, 60sec for each time) for enhanced reagent infiltration in dense or fatty tissue specimens. All other specifications are identical. Choose RD-501 for research settings or when processing particularly dense tissue types.
Does the RD-500 have power-off protection?
Yes. The RD-500 features power-off protection that automatically resumes operation from the last memory position after power recovery. This prevents tissue sample loss during unattended overnight processing if a power interruption occurs. Additionally, the delayed start function can schedule operations up to 1 month in advance.
How are reagents prevented from mixing during cylinder changes?
The RD-500 features a 5-second draining period at the top position during automatic cylinder changes. This allows residual reagent to drain back into its cup before the basket moves to the next station, effectively preventing reagent carryover and cross-contamination between processing steps.
Need a Reliable Carousel Tissue Processor?
The Roundfin RD-500 features a 12-cup carousel design, 10 programmable protocols, automatic cylinder change with drain protection, delayed start up to 1 month, power-off protection, dual safety limiters, and obstacle detection. CE and ISO 13485 certified with 1 year and whole lifetime technical support. RD-501 vacuum model also available.
