Product Overview
The Roundfin RD-501 is a carousel-type automatic tissue processor with built-in vacuum function, designed for histology and pathology laboratories requiring enhanced reagent infiltration for dense or fatty tissue specimens. Based on the proven 12-cup carousel platform, the RD-501 adds programmable vacuum cycles (-60kpa (Optional:-70KPA/-55KPA)) to the standard atmospheric processing, providing superior dehydration, clearing, and paraffin infiltration for demanding tissue types.
Featuring 1 (2 basket optional) sample baskets for parallel batch processing, built-in basket rotation every 5 minutes for thorough reagent mixing, 10 built-in programs supporting 12 processing steps with adjustable immersion times from 0-2000 minutes per cup, automatic cylinder change with a 5-second draining period to prevent reagent cross-contamination, and a delayed start function up to 1 month in advance. Vacuum pump cycles operate at 5 times/min, 60sec for each time for consistent reagent penetration. CE and ISO 13485 certified with 1 year and whole lifetime technical support.

Why Choose the Vacuum Model (RD-501)
Enhanced reagent infiltration: -60kpa (Optional:-70KPA/-55KPA) vacuum cycles accelerate reagent penetration into dense, fatty, or thick tissue specimens -- reducing processing time while maintaining quality.
Programmable vacuum: 5 times/min, 60sec for each time for consistent, reproducible vacuum-assisted processing across all specimens in a batch.
Parallel batch processing: 1 (2 basket optional) baskets for higher throughput compared to the single-basket RD-500.
Identical platform: All other features -- 12-cup carousel, 10 programs, 12 processing steps, automatic cylinder change, power-off protection, delayed start, safety limiters, and obstacle detection -- are shared with the trusted RD-500 platform.
Key Features
Vacuum-Assisted Processing -- -60kpa (Optional:-70KPA/-55KPA) vacuum with programmable pump cycles (5 times/min, 60sec for each time) enhances reagent infiltration for dense and fatty tissue specimens.
Automatic Cylinder Change -- 5-second draining at the top position prevents reagent carryover between processing stations.
Basket Rotation -- Built-in rotation every 5 minutes (5 times/min, 60sec for each time) for thorough reagent mixing and complete tissue reactions.
Aluminum Reagent Cylinders -- Lightweight with handles; glass optional. Safer handling than traditional glass cylinders.
Dual Safety Limiters -- Internal software + external mechanical limiter prevent component damage. Obstacle detection sensor stops operation when foreign objects are detected.
10 Built-in Programs -- 12 processing steps each, immersion 0-2,000 min/cup (1-min intervals).
Power-Off Protection -- Resumes from last memory position after power recovery -- no sample loss.
Delayed Start -- Schedule processing up to 1 month in advance for overnight or weekend operation.

| Research Institute | Programmable vacuum for reproducible processing across varied tissue types. 1 (2 basket optional) baskets for parallel batch runs. |
| Veterinary Pathology | Vacuum penetration for dense animal tissue. 1.3 (2.3L optional)L or 2.3L cup capacity for flexible throughput. |
| Medical University / Teaching Hospital | Demonstrate vacuum vs atmospheric comparison. Obstacle detection and safety limiters protect during training. |
FAQ
What is the vacuum level of the RD-501?
The RD-501 achieves -60kpa (Optional:-70KPA/-55KPA) with optional settings of -70KPA or -55KPA. Vacuum pump cycles operate at 5 times/min, 60sec for each time for consistent reagent penetration across all specimens in a batch.
What is the difference between RD-500 and RD-501?
The RD-500 (atmospheric model) has 1 basket. The RD-501 adds a -60kpa (Optional:-70KPA/-55KPA) vacuum function with programmable cycles and supports 1 (2 basket optional) baskets. All other features -- 12-cup carousel, 10 programs, auto cylinder change, power-off protection, safety features -- are identical between both models.
When should I choose RD-501 over RD-500?
Choose RD-501 if your lab processes dense tissue (lipomatous, fibrotic, large resections), needs faster processing for urgent specimens, requires higher throughput (1 (2 basket optional) baskets vs 1), or has research protocols requiring consistent vacuum-assisted infiltration. Choose RD-500 for standard routine histology processing.
Does the RD-501 have power-off protection?
Yes. The RD-501 resumes operation from the last memory position after power recovery, preventing sample loss during unattended overnight or weekend processing.
