The Roundfin RS-5 Tissue Stainer is an eco-friendly, fully automatic staining station designed for routine and special staining of tissue cells in pathology laboratories. It can perform both routine and special staining simultaneously or independently, delivering excellent staining results. The RS-5 supports over 4 programs and 10 racks running simultaneously without interference, with rack status displayed in real time, achieving a throughput of up to 400 specimens per hour. Medigear.uk supplies the RS-5 and can advise on configuration and installation.

The instrument has 36 total stations, including 26 reagent tank sites and five washing stations. Reagent tank volume is 500ml per tank. The loading capacity supports up to 10 staining racks for different programs simultaneously. Programme storage capacity is 10 programs. A 10.4-inch (22.5×13.5cm) colour touch screen provides easy operation and real-time display of staining programs and processes. Staining programs can be started via colour code and shown in real time for clear monitoring.

The robotic arm performs shaking, draining, and liquid-throwing to reduce dye carryover between racks. The 1st, 2nd, 13th, and 14th cylinders are heated for more complete reactions and better specimen quality. Reagent tank access priority can be set across three levels, with Level 3 the highest, enabling priority management when multiple programs run simultaneously. Two stations can be set as empty, and the staining process is auto-optimised for multiple racks. After a fault stop, the instrument resumes from the memorised position to maximise specimen utilisation.

Operating temperature range is 5°C–35°C. Product dimensions are 1050mm×615mm×590mm (L×W×H). Weight is 80KGS. Power supply is AC220V±22V, 50Hz. Power is 200W. Certification covers CE and ISO 13485. Warranty covers 1 year and lifetime technical support. Customisation is available. We can provide the full specification and supply terms on request.

NHS histopathology departments, hospital diagnostic laboratories, and high-volume pathology services that require a fully automatic tissue staining station with high multi-rack throughput are the primary procurement context for the Roundfin RS-5 Tissue Stainer. The ability to run over four programs and ten racks simultaneously without interference, delivering up to 400 specimens per hour, makes the RS-5 well-suited for demanding diagnostic staining environments where daily specimen volumes require concurrent processing of multiple staining protocols at high slide throughput. Medigear.uk supplies the RS-5 and can provide NHS procurement documentation.

NHS cancer diagnostic centres, specialist pathology services, and cytology laboratories benefit from the RS-5's ability to perform routine and special staining simultaneously or independently within the same instrument. The three-level reagent tank access priority system enables management of protocol priorities when multiple programs share reagent resources, ensuring that high-priority diagnostic staining protocols receive precedence over lower-priority batches in a concurrent multi-rack processing environment.

Research institutions, medical school histopathology departments, and specialist staining services benefit from the RS-5's ten programmable protocols, colour-coded program start system, and fault-resume-from-memorised-position feature that maximises specimen utilisation even after operational interruptions. The robotic arm's dye carryover reduction via shaking, draining, and liquid throwing supports consistent staining quality across protocols and dye concentrations. Medigear.uk can advise on RS-5 configuration for research and educational procurement.

Private pathology laboratories and commercial histopathology services requiring high-throughput automated tissue staining with minimal manual intervention will find the Roundfin RS-5 available through Medigear.uk. The user authorisation system with password and barcode dye management, optional exhaust air filtration, and optional oven function extends the instrument's operational capability for commercial and specialised laboratory environments. Medigear.uk can discuss RS-5 supply terms and configuration options on request.

10-Rack Simultaneous Multi-Program Processing

The RS-5 processes up to 10 staining racks for different programs simultaneously, without interference between protocols, and displays rack status in real time. This simultaneous multi-rack, multi-program capability is the defining throughput advantage of the RS-5, enabling the concurrent execution of diverse staining protocols — routine haematoxylin and eosin alongside special stains, for example — without the sequential processing bottleneck of instruments with lower concurrent capacity.

400 Specimens Per Hour Throughput

The RS-5's throughput of up to 400 specimens per hour reflects the combined effect of its 36-station layout, 10-rack simultaneous capacity, and robotic arm automation. For NHS histopathology departments and commercial laboratories processing hundreds of diagnostic specimens daily, this throughput level provides the instrument capacity to maintain workflow pace amid demanding workloads without making staining a rate-limiting step in the diagnostic process.

Simultaneous Routine and Special Staining

The ability to perform routine and special staining simultaneously or independently on the same instrument is a significant workflow advantage for laboratories that regularly process both staining types. Rather than dedicating separate instruments to routine and special staining, or processing them sequentially on a single instrument, the RS-5 accommodates concurrent protocol execution with priority management to control resource allocation between protocols.

Robotic Arm for Active Dye Carry-Over Reduction<|join|>Robotic Arm for Active Dye Carry-Over Reduction

The robotic arm's active shaking, draining, and liquid-throwing operations between station transitions reduce dye carry-over that would otherwise contaminate reagents and degrade staining consistency across concurrent multi-protocol processing. This active carry-over management supports staining quality in the demanding concurrent multi-rack environment where passive drainage alone is insufficient to prevent cross-contamination between protocols with different dye concentrations.

Three-Level Reagent Priority Management

The three-level reagent tank access priority system provides structured management of resource contention when multiple programs compete for the same station in a concurrent 10-rack processing environment. By assigning priority levels to programs, the laboratory can ensure that the most time-critical or diagnostically important protocols receive priority for station access, preventing lower-priority batch processing from delaying urgent diagnostic staining.

Fault-Resume From Memorised Position<|join|>Fault-Resume From Memorised Position

After a fault stop, the RS-5 resumes at the exact memorised position in the staining protocol rather than restarting from the beginning, preserving the staining progress already achieved. This feature directly reduces specimen loss during operational interruptions. It is particularly valuable for long special staining protocols in which restarting from the beginning would result in specimens that cannot be rescued or reprocessed within the working day.

Heated Cylinders for Optimal Reagent Reactivity

The heated 1st, 2nd, 13th, and 14th cylinders provide targeted temperature control for temperature-sensitive staining reagents at protocol positions that benefit from elevated temperatures, supporting more complete chemical reactions and better specimen quality than room-temperature processing alone. This selective heating approach optimises reaction conditions without unnecessarily heating all reagent stations.

Colour-Coded Program Identification for Multi-Rack Monitoring

Staining programs can be started via colour code and shown in real time on the touch screen, providing clear visual identification of which program each rack is executing in a concurrent 10-rack processing environment. This colour coding reduces the cognitive load of monitoring multiple simultaneous protocols and supports rapid identification of any specific rack's current protocol status during the working session.

FAQ

Frequently Asked Questions

Everything buyers need to know about sourcing medical equipment through MediGear.

The RS-5 supports up to 10 staining racks for simultaneous processing of different programs, with rack status displayed in real time. The instrument supports over 4 programs and 10 racks running simultaneously without interference between protocols. This simultaneous multi-rack, multi-program capacity allows the laboratory to process diverse staining protocols concurrently rather than sequentially, significantly increasing daily throughput and reducing total turnaround time compared to single-rack or single-program automated stainers.

The RS-5 achieves a throughput of up to 400 specimens per hour, reflecting the combined effect of its 36 stations, 10-rack simultaneous capacity, and robotic-arm automation across shaking, draining, and liquid-throwing operations. This high throughput makes the RS-5 appropriate for high-volume NHS histopathology departments and commercial laboratories where daily specimen volumes require sustained, rapid staining capacity throughout the working day.

Yes — the RS-5 can perform both routine and special staining either simultaneously or independently within the same instrument session. The three-level reagent tank access priority system supports priority management when multiple programs with different reagent requirements run concurrently, ensuring that high-priority protocols receive reagent access before lower-priority batches. This simultaneous routine and special-staining capability eliminates the need for separate instruments or for sequential processing of different staining types.

The RS-5's robotic arm performs shaking, draining, and liquid-throwing operations to reduce dye carryover between racks and stations. Dye carry-over occurs when residual staining reagent is carried from one reagent tank to the next on slides or rack components, potentially contaminating reagents and affecting staining quality. The robotic arm's active shaking and draining actions reduce residual reagent on slides and racks before each station transition, maintaining reagent purity and supporting consistent staining quality across concurrent multi-protocol processing.

The reagent tank access priority system allows the laboratory to assign one of three priority levels to each staining program, with Level 3 being the highest priority. When multiple programs run simultaneously and need to access shared reagent stations, the priority system determines which program takes precedence, ensuring that the most time-critical or diagnostically important staining protocol receives access to the station first. This priority management is essential for a 10-rack concurrent processing environment where resource contention between programs must be managed systematically.

After a fault stop, the RS-5 resumes processing from the memorised position — the specific point in the staining protocol where the instrument stopped — rather than restarting from the beginning of the protocol. This fault-resume-from-memorised-position feature maximises specimen utilisation by preserving the staining progress already achieved before the fault, preventing slides from being discarded due to incomplete staining after an operational interruption. This is particularly valuable for long or complex staining protocols, where restarting from the beginning would result in a significant loss of processing time and specimen quality.

The RS-5 includes multiple alarm functions: an alarm if the glass cover is not properly closed before operation begins; automatic prompts for reagent replacement after repeated use cycles that have depleted reagent quality; and an alarm if the download drawer is full or not properly closed. These targeted alarms address the three most common operational errors that can compromise staining quality or instrument operation, alerting the operator to specific actionable conditions rather than providing generic fault notifications.

The 1st, 2nd, 13th, and 14th cylinders are heated to promote more complete chemical reactions and improve specimen quality during staining. Heating specific reagent stations enhances the reactivity of temperature-sensitive staining reagents, improving the completeness of staining reactions — particularly relevant for protocols in which room-temperature reaction kinetics are insufficient for optimal staining quality. The selective heating of specific stations, rather than all stations, provides targeted temperature control matched to the reagent requirements of those positions in the staining sequence.

Two optional features are available: an exhaust air filtration system to manage solvent vapour in the laboratory environment, and an oven function for slide drying and tissue adherence protocols that require elevated-temperature pre-treatment. A user authorisation system with password and barcode dye management is also available as an option, supporting controlled access to dye management functions for laboratories with multi-user access control requirements. Medigear.uk can confirm the specification and availability of optional features on request.

The RS-5 is a standalone tissue-staining station, while the RF-3000A is an integrated slide-stainer and glass coverslipper workstation. The RS-5 has more stations (36 vs 28 on the RF-3000A stainer), a higher stated throughput (400 specimens per hour), and a larger simultaneous processing capacity (10 racks vs 30 slides per run on the RF-3000A). The RF-3000A adds automatic coverslipping capability directly after staining, creating an end-to-end staining-to-filing workflow. Medigear.uk can provide a full comparison between the RS-5 and RF-3000A to support procurement decisions.
