ROUNDFIN RD-2290

Intraoperative pathology services require cryostat microtomes capable of delivering reliable frozen section results within the tight time constraints of active surgical procedures. The RD-2290 addresses this through its 15-minute working time to -80°C, 24 freezing stations for simultaneous specimen staging, six semiconductor stage cooling points, and an anti-stick device maintained at -50°C for smooth specimen handling. The UVC ultraviolet disinfection system manages infection control governance between cases without extended manual cleaning. Medigear.uk provides CE and ISO 13485 certification documentation to support procurement approval for the acquisition of intraoperative pathology equipment.

Routine diagnostic histopathology laboratories processing diverse specimen categories benefit from the RD-2290's dual section-thickness ranges — 0.5μm–100μm and 1μm–600μm — and five-point independent cooling, which allows each thermal component to be optimised for the tissue type in use. The ≤47dB(A) noise rating makes the RD-2290 well-suited to laboratory environments where operator comfort is prioritised alongside clinical performance. The dual SECOP compressor architecture provides greater refrigeration redundancy than single-compressor alternatives. Medigear.uk supplies pre-purchase consultation and technical documentation for procurement teams evaluating the RD-2290.

Research institutions, teaching hospitals, and specialist pathology facilities benefit from the 10.1-inch multilingual touch screen, sleep mode with automatic temperature maintenance between -5°C and -15°C, and USB and TF card interfaces for digital data logging. ROUNDFIN's OEM acceptance policy enables distributors to source branded variants through the Medigear—UK B2B procurement channel.

Individual buyers and private pathology services can acquire the RD-2290 directly through Medigear.uk. The heated glass window prevents condensation during extended sessions, and ROUNDFIN's warranty and lifetime technical support commitment provide long-term operational assurance.

Dual SECOP Brand Compressors for Refrigeration Reliability and Redundancy

The RD-2290 uses two SECOP-brand dual air compressors — internationally recognised professional refrigeration components — providing both the cooling capacity required for five-point independent zone management and the operational redundancy of a dual-compressor architecture. Single-compressor cryostat designs are more vulnerable to complete cooling loss due to a single-component failure. In contrast, the dual-compressor design in the RD-2290 maintains partial cooling capacity if one compressor requires servicing. SECOP's established global supply chain also ensures reliable availability of spare parts for long-term service continuity. Medigear.uk can provide compressor specification documentation for procurement assessments.

-65°C Minimum Freezing Shelf Temperature

The -65°C minimum shelf temperature provides the deep, rapid cooling needed for fresh tissue specimens that require low temperatures to achieve the frozen consistency necessary for clean, artefact-free sectioning. This temperature is particularly important for lipid-rich, fatty, and cell-dense tissue types that cannot be adequately frozen at the -45°C range of less powerful cryostat systems. The -65°C lower limit also provides a thermal safety margin for urgent intraoperative specimen requests where rapid initial freezing is operationally critical. Medigear.uk can advise on tissue-specific pre-freezing protocols that make use of the full -65°C capability.

Five-Point Independent Cooling Including Anti-Stick Device

Five independently controlled cooling zones — freezing chamber, specimen clamp, knife holder, specimen head, and anti-stick device — each allow separate temperature optimisation without any zone affecting the others. The inclusion of the anti-stick device as a dedicated cooled zone at -50°C is a specific design feature of the RD-2290 that directly addresses the section adhesion problem common in cryostat sectioning of certain tissue types. This five-point coverage provides more granular thermal management than competitive three- or four-zone designs.

≤47dB(A) Noise Rating for Laboratory Comfort

The RD-2290's noise rating of ≤47dB(A) during operation is comparable to quiet conversation, making it one of the quietest cryostat microtomes in its performance class. This low noise level is a direct result of the unit's dual SECOP compressor engineering and vibration-management design. Laboratories in shared buildings, adjacent to patient areas, or with occupational noise management requirements can reference the 47dB(A) specification in equipment suitability assessments without further acoustic testing. Medigear.uk can provide acoustic performance documentation as part of the pre-purchase technical pack.

Dual Section Thickness Ranges Covering 0.5μm to 600μm

Section thickness control across two overlapping ranges — 0.5μm–100μm for thin to standard sections and 1μm–600μm for standard to thick sections — with multiple increment options within each sub-range provides precise, protocol-matched thickness selection across all histological section types. This dual-range architecture eliminates the need for separate instruments for different protocol categories. It supports the full spectrum, from ultra-thin fluorescence sections to thick enzyme histochemistry preparations, within a single system.

CE and ISO 13485 Certification for Regulated Procurement

The RD-2290 carries CE marking and ISO 13485 certification — the latter confirming that ROUNDFIN's quality management system for the RD-2290 meets international medical device manufacturing standards. Not only that, but the finished product has passed product-level testing. ISO 13485 is specifically required in many NHS trusts and regulated laboratory procurement frameworks as evidence of supplier quality management system compliance. Medigear.uk provides complete certification documentation, technical file summaries, and manufacturer declarations to support institutional procurement submissions of any complexity.

10.1-Inch Multilingual Colour Touch Screen

The 10.1-inch colour touch screen provides a large, clear interface for all parameter setting, status monitoring, and data management functions, with multilingual display support for laboratories operating in diverse language environments. The large screen size is a practical advantage over smaller display formats in busy sectioning sessions where operators need to confirm settings and check status at a glance without interrupting the sectioning workflow. USB and TF card data interfaces extend the screen's functionality to digital parameter logging and session data export.

UVC Ultraviolet Disinfection System

The integrated UVC ultraviolet lamp provides automated cabinet disinfection between cases, addressing cross-contamination risk management requirements in shared cryostat environments without requiring manual chemical cleaning of the chamber interior. The system supports both manual and scheduled timed disinfection cycles with adjustable duration. In intraoperative pathology settings where multiple surgical cases may generate frozen section requests within overlapping windows, the UVC disinfection capability supports rapid turnaround between cases while maintaining infection control standards.

500W Rated Power for Energy-Efficient High Performance

At 500W, the RD-2290 delivers dual SECOP compressor performance and five-point independent cooling down to -65°C, with power consumption competitive with less capable single-zone cryostat designs. The 500W rating combined with the sleep mode — which reduces the thermal load to maintain -5°C to -15°C during inactivity — supports both high performance during active sessions and economical operation during extended periods between cases. Medigear.uk can provide power consumption data for combined session and standby modes as part of the pre-purchase technical documentation.

Section Thickness Range 1: 0.5μm–100μm, Variable Increments

Section thickness from 0.5μm to 100μm with increments of 0.5μm (0.5μm–50μm), 1μm (5μm–20μm), and 5μm (20μm–100μm) depending on the sub-range selected. This range and increment combination provides resolution for ultra-thin fluorescence and immunofluorescence sections through to standard diagnostic sections within a single range.

Section Thickness Range 2: 1μm–600μm, Variable Increments

Section thickness from 1μm to 600μm with increments of 1μm (1μm–50μm), 5μm (50μm–100μm), and 10μm (100μm–600μm). This overlapping range extends from thin diagnostic sections through to thick enzyme histochemistry preparations, covering specialist and research protocol requirements within the same instrument.

Trimming Thickness Range: 1μm–600μm, Variable Increments

Trimming thickness is adjustable from 1μm to 600μm with increments of 5μm, 10μm, or 50μm across sub-ranges. The trimming range enables rapid block-face preparation before switching to section mode, and the adjustable increment controls the volume of tissue removed per trimming stroke.

Specimen Retraction: 1–95μm, 2μm Increment

Specimen retraction withdraws the tissue block by 1 to 95 μm in 2 μm increments between strokes, preventing the cut section face from dragging across the blade on the return stroke and reducing the risk of surface distortion.

Vertical Specimen Movement: 65mm

The 65mm vertical specimen movement range accommodates standard and oversized frozen tissue blocks, supporting consistent sectioning across both small biopsy specimens and larger resection blocks without stage repositioning.

Horizontal Specimen Movement: 25mm

The 25mm horizontal movement provides lateral positioning adjustment for bloc-centring and specimen orientation optimisation within the cutting plane.

Specimen Head Rotation: X-axis 360°, Y-axis 12°

Full 360° rotation on the X-axis and 12° on the Y-axis allow complete specimen face orientation and tilt correction to align with the blade plane before sectioning commences.

Freezing Chamber Temperature: 10°C to -50°C

The main chamber is independently controlled from 10°C to -50°C, maintaining the cryostat's internal environment at the optimal temperature for the tissue and protocol in use throughout each session.

Specimen Clamp Temperature: 0°C to -50°C

The specimen clamp is independently controlled from 0°C to -50°C, allowing the chuck and mounted tissue to be maintained at a temperature appropriate for the specific tissue type being sectioned.

Minimum Freezing Shelf Temperature: -65°C

The freezing shelf reaches a minimum of -65°C, providing deep initial cooling for fresh specimens and lipid-rich tissue types that require lower temperatures for adequate frozen consistency before sectioning.

24 Freezing Stations, including 6 Semiconductor Stage Cooling Points

Twenty-four specimen freezing points, including six semiconductor-stage cooling points, support simultaneous staging and processing of multiple specimens at different preparation stages, thereby enabling high-throughput intraoperative and routine frozen-section workflows.

Working Time to -80°C: 15 Minutes

The cryostat reaches -80°C from ambient standby in 15 minutes, supporting rapid session initiation and minimising wait time for urgent intraoperative specimen requests.

Dual SECOP Brand Compressors

Two SECOP brand air-compressors provide the cooling capacity and redundancy for five-point independent zone management down to -65°C minimum shelf temperature. SECOP is an internationally recognised professional refrigeration brand.

Anti-Stick Device: -50°C

The dedicated anti-stick device is independently cooled to -50°C, preventing frozen sections from adhering to blade and chamber surfaces during the cutting stroke and supporting clean section lift-off across diverse tissue types.

Speed: 0.45–1.8mm/s Stepless Regulation

Fast-forward and back-forward speeds are continuously variable from 0.45 mm/s to 1.8 mm/s with stepless regulation, enabling advanced speed optimisation for different block sizes, tissue consistencies, and sectioning protocols.

Noise: ≤47dB(A)

Operational noise is rated at ≤47dB(A), within the quiet conversation range. This low acoustic output is suitable for shared laboratories, teaching environments, and facilities with noise management requirements.
