Roundfin RD-G-01

Pathology laboratories and hospital mortuary departments are the primary setting for the Roundfin RD-G-01 Formalin Dispenser. Accurate formalin delivery is a routine requirement in pathology for tissue fixation, specimen preservation, and post-mortem preparation. The LCD automatic dosing system and adjustable perfusion pressure allow technicians to deliver consistent volumes precisely calibrated to different tissue types, supporting reproducibility across cases. Medigear.uk supplies the RD-G-01 to NHS trust pathology departments and can provide CE/ISO 13485 documentation for compliance review.

Operating theatres that use formalin for intraoperative specimen fixation benefit from the RD-G-01's compact footprint, downdraft ventilation, and hands-free foot-pedal control. The under-0.5-square-metre base allows the dispenser to be positioned within the instrument zone without obstructing workflow. The vascular blockage alarm and automatic spill recovery reduce the risk of contamination in theatre environments, where floor incidents carry significant safety implications. Medigear.uk can discuss installation options for theatre-based buyers.

Anatomy teaching laboratories and cadaver preparation facilities benefit from the RD-G-01's dual perfusion capability and three-stage exhaust sterilisation. The dual perfusion mode supports simultaneous delivery to two cadavers, with independent flow monitoring and blockage detection for each circuit. The ion generator and carbon filtration reduce formalin vapour levels in enclosed suites, thereby supporting compliance with occupational exposure limits for regular anatomy staff. Medigear.uk can advise on ventilation compatibility for anatomy suite installations.

Independent research laboratories and specialist distributors will find the RD-G-01 available through Medigear.uk with full specification support. The 18 kg weight and four-wheel mobility allow a single dispenser to be relocated between rooms as needed. A 1-year warranty and lifetime technical support are included as standard, and OEM arrangements are available to authorised distributors placing bulk orders through Medigear.uk.

CE/ISO 13485 Certification — Medical Device Quality Standard

The RD-G-01 is certified to both CE and ISO 13485, with ISO 13485 being the internationally recognised quality management standard specific to medical device design, manufacture, and supply. This certification level is above the general ISO 9001 standard and is the benchmark expected in NHS medical device procurement frameworks. Medigear.uk has the full certification documentation on file and can provide it to procurement officers and medical device governance teams during due diligence, without delaying the purchasing timeline.

Simultaneous Dual Corpse Perfusion with Blockage Alarm

The ability to perfuse two corpses simultaneously from a single dispenser significantly increases throughput in pathology and anatomy environments where multiple cadavers require formalin delivery in the same session. Each perfusion circuit is independently monitored by the vascular blockage alarm, which alerts operators specifically to flow obstructions in either circuit without interrupting the other. This independent monitoring prevents an obstruction in one circuit from masking a normal flow condition in the other, which would be a risk in a shared-alarm configuration.

LCD Automatic Dosing with mmHg Pressure Adjustment

The full LCD menu provides access to automatic dosing functions, allowing operators to programme pre-set formalin volumes for consistent delivery without manual measurement during each procedure. Perfusion pressure is adjustable in millimetres of mercury, giving clinicians and anatomy technicians a clinically familiar pressure unit that aligns with the vascular physiology parameters they work with in practice. The combination of automatic dosing and pressure-controlled delivery supports reproducible perfusion protocols across different cadavers, tissue types, and institutional fixation standards.

Three-Stage Exhaust Sterilisation for Enclosed Environments

The exhaust system progressively treats extracted formalin gas through fan extraction, ion decomposition, and carbon filtration before any air is released from the unit. This three-stage arrangement is effective even where exhaust cannot be vented directly outdoors, making the RD-G-01 deployable in enclosed anatomy suites, inner-corridor pathology rooms, and theatre environments where external duct connections are unavailable. The ion generator specifically decomposes harmful compounds rather than simply filtering particles, providing a deeper level of chemical treatment than fan-and-filter-only systems.

Downdraft Ventilation Containing Fumes at Source

The downdraft ventilation design draws formalin vapour downward and into the extraction path at the work-surface level, rather than allowing it to rise into the operator's breathing zone. This containment approach is recognised as more effective than lateral or upward extraction for bench-level chemical vapour sources because it intercepts fumes before they reach face height. This feature is particularly significant for the RD-G-01's operating theatre application, where fumes rising into the operative field would represent both an occupational exposure and a sterility concern.

Hands-Free Foot Pedal and Induction Control

The foot pedal control mode allows the operator to start and stop formalin flow without removing hands from the corpse or the instruments in use, which is the standard operating preference in perfusion procedures where both hands are continuously occupied. The induction control mode provides a non-contact activation alternative for settings where foot pedal access is restricted or where a touchless interface is preferred for hygiene reasons. Both control modes are available on the standard unit without additional configuration.

Compact Sub-0.5 m² Footprint with Four-Wheel Mobility

The 390 × 390 mm base footprint keeps the RD-G-01 well within the instrument zone dimensions of standard operating theatres and pathology preparation benches without requiring dedicated floor space or fixed installation. The four universal wheels allow the unit to be repositioned within or between rooms by a single operator, which is particularly valuable in multi-function preparation facilities where the dispenser is shared across different preparation areas. At 18 kg, the unit is light enough for standard manual handling without specialist equipment.

Automatic Spill Recovery System

The integrated automatic spill recovery system detects internal formalin spills and returns them to the tank without requiring operator intervention. This reduces reagent waste during dispensing operations, prevents formalin from accumulating at the base of the unit, where it could cause corrosion or hygiene concerns, and reduces the frequency of manual cleaning inside the enclosure. In facilities where formalin is managed as a controlled chemical waste stream, automatic recovery also reduces the volume of formalin entering the waste system from accidental spills.

OEM Supply Accepted with Negotiable Customisation

The RD-G-01 is available under OEM supply arrangements for authorised distributors, and customisation is confirmed as negotiable through the Medigear.uk procurement team. The RD-G-01 is a viable platform for medical equipment distributors seeking a CE/ISO 13485-certified formalin dispenser for their product portfolio. If you have specific labelling, configuration, or operational requirements, please get in touch with Medigear.uk to explore available options. We include lifetime technical support as standard, providing OEM partners with meaningful post-sale assurance when they integrate the RD-G-01 into their support offering.

Material: 304 Stainless Steel Body

The entire outer body of the RD-G-01 is fabricated from 304 stainless steel, providing resistance to formalin, chemical disinfectants, and moisture in laboratory and preparation room environments. Grade 304 is the established material standard for equipment in sustained contact with chemical reagents in pathology and anatomy settings. Medigear.uk can supply the material specification sheet on request.

Capacity: 50L System / 20L Formaldehyde Tank

The RD-G-01 accommodates a 20-litre formaldehyde tank within the unit body, with an overall system capacity that meets the dispensing and storage requirements of pathology and anatomy sessions. The 50-litre total system capacity covers extended perfusion sessions without requiring mid-procedure reagent replenishment. Medigear.uk can advise on compatible formaldehyde tank specifications and refill procedures.

LCD Full Menu Operation with Automatic Dosing

A full LCD menu panel provides access to all dispensing parameters, including dose volume, perfusion pressure, and flow rate. Automatic dosing mode allows pre-programmed volumes to be delivered consistently across multiple procedures without manual measurement at each step. The LCD interface provides a real-time display of system status, reagent level, and alarm conditions during operation.

Adjustable Perfusion Pressure in mmHg

The perfusion pressure is adjustable in millimetres of mercury, allowing operators to fine-tune the delivery pressure to match the vascular condition and physiological state of each corpse. This adjustment range enables the same unit to be used across a range of preservation procedures, from fresh cadaver perfusion to specimens in varied stages of post-mortem change, without compromising delivery consistency.

Discharge Flow Rate: 0.5–1.0 L/min

The discharge flow rate is adjustable between 0.5 and 1.0 litres per minute using a precision flow valve. This range supports both slow, controlled tissue infiltration at the lower end and faster bulk delivery at the upper end, giving operators control over the formalin delivery speed appropriate to the specific procedure and tissue type.

Simultaneous Dual Corpse Perfusion

Two corpses can be perfused simultaneously from a single RD-G-01 unit. Each circuit operates independently, with the vascular blockage alarm providing per-circuit monitoring. This dual capability effectively doubles the throughput of a single dispenser in environments where two cadavers require concurrent formalin delivery, reducing the number of units needed for a given programme capacity.

Vascular Blockage Alarm

A vascular blockage alarm is integrated into each perfusion circuit. It activates when flow obstruction is detected, alerting the operator before back-pressure builds to a level that could damage the tissue or the dispensing equipment. The alarm is independent per circuit in dual-perfusion mode, ensuring that a blockage in one line does not mask continued flow in the other.

Foot Pedal and Induction Control

Two control modes are provided: foot pedal and induction. Foot pedal operation is the preferred hands-free mode during active perfusion procedures. Induction control provides a non-contact alternative for settings where foot pedal access is impractical or where touchless operation is preferred. Both modes are available without additional configuration on the standard unit.

Automatic Spill Recovery

Internally spilt formalin is automatically detected and recovered to the tank without requiring operator intervention. This reduces waste, prevents internal accumulation of reagent, and minimises the need for manual internal cleaning between sessions. The spill recovery system operates passively as a standard function of the unit rather than requiring activation.

Three-Stage Exhaust: Fan, Ion Generator, Carbon Filter

The exhaust system treats extracted formalin gas through three sequential stages before venting. A low-noise fan provides initial extraction from the work area. An ion generator at the exhaust outlet decomposes harmful chemical compounds. Activated carbon filtration provides the final treatment layer. This arrangement is effective in enclosed settings without an external duct connection and provides a higher level of vapour treatment than single-stage filter systems.

Downdraft Ventilation Design

The ventilation geometry of the RD-G-01 directs fumes downward and into the extraction path at work-surface level, preventing formalin vapour from rising into the operator's breathing zone. This containment approach is a meaningful occupational health feature in enclosed pathology, theatre, and anatomy environments. It is particularly relevant where ceiling heights or room layouts limit the effectiveness of overhead extraction.

Power: 200W at 220V ±10V, 50Hz ±1Hz

The unit operates at 200W on a standard 220V single-phase supply, making it compatible with standard laboratory and theatre electrical installations. The low 200W power rating reduces running costs relative to higher-wattage alternatives and generates minimal heat during operation. Medigear.uk can provide the full electrical specification sheet for facilities compliance review.

Four Universal Wheels for Laboratory Mobility

Four universal wheels are fitted to the base of the RD-G-01, allowing the unit to be moved freely across laboratory, theatre, or preparation room floors by a single operator. The wheels support repositioning between rooms or between preparation areas within a facility without requiring the unit to be lifted or carried. Medigear.uk can confirm wheel lock specifications and floor compatibility for buyers with specific flooring materials.

CE/ISO 13485 Certification

CE and ISO 13485 certifications have been confirmed for the RD-G-01. ISO 13485 is the medical device quality management standard and provides a recognised assurance of manufacturing quality and safety above the general ISO level. Medigear.uk holds all certification documentation and can provide it to NHS procurement officers and institutional compliance teams on request.
