The Roundfin RD-1601B Microtome Blade is a high-profile stainless steel microtome blade designed for paraffin sectioning and cryostat applications in diagnostic histopathology and research histology laboratories. The blade is manufactured from X46cr13 stainless steel — a martensitic steel grade providing the hardness and edge retention required for consistent histopathology microtomy — with a PTFE coating applied to the blade surface to reduce friction between the blade and the paraffin wax block during sectioning. The PTFE coating also reduces wax adhesion to the blade surface, helping maintain consistent section quality across the service life of each blade. Medigear.uk supplies the Roundfin RD-1601B and can advise on specification and procurement.

The blade body measures 80mm×14mm with a thickness of 0.325mm. The 14mm body width is the standard width for the high-profile blade holder format, and the high-profile designation indicates the blade is designed for use in high-profile knife rests and high-profile microtome blade holders — including those on most major microtome platforms. The RD-1601B is thicker than the low-profile RD-1601A (0.325mm versus 0.25mm), reflecting the dimensional requirements of the high-profile blade holder geometry. The cutting angle is 35°, the standard angle for routine paraffin and cryostat sectioning. Roundfin cites the proprietary manufacturing process as ensuring edge quality and durability, supporting faster sectioning and longer blade service life per unit.

Each RD-1601B box contains 50 blades in a standard dispenser box format and weighs 150g. The dispenser box allows individual blades to be removed without handling adjacent blades, reducing sharps exposure during blade change. The RD-1601B is compatible with most microtomes and cryostats and is available through Medigear.uk in both single-box and volume supply. Contact Medigear.uk to confirm availability, pricing, and minimum order quantities for the RD-1601B.

NHS histopathology departments, hospital pathology laboratories, and diagnostic services requiring a consistent high-profile stainless steel PTFE-coated microtome blade for routine daily paraffin sectioning represent the primary procurement context for the Roundfin RD-1601B Microtome Blade. The X46cr13 steel grade and PTFE coating combination is designed to deliver excellent cutting and long service life for various tissue specimens, reducing the frequency of blade changes in high-volume sectioning environments. The 35° cutting angle is consistent with the standard for diagnostic paraffin histopathology, supporting reliable section quality across routine tissue types. Medigear.uk supplies the RD-1601B and can provide NHS procurement documentation and regular supply terms.

Surgical pathology departments, cancer diagnostic centres, and high-throughput histopathology services with large daily section volumes benefit from the RD-1601B's PTFE coating, which reduces friction at the blade-block interface and supports cleaner, more consistent sections across the service life of each blade. Reducing wax adhesion to the blade surface also helps maintain section quality toward the end of a blade's cutting life, extending the number of usable sections per blade change and reducing sharp waste volume. The 50-blade dispenser box format supports consistent stock rotation and reordering. Medigear.uk can advise on regular supply contracts and volume pricing for the RD-1601B.

Cryostat and frozen section services — including intraoperative pathology and research fresh tissue work — benefit from the RD-1601B's compatibility with most cryostats. The high-profile format covers the high-profile cryostat blade holder configuration used across compatible cryostat platforms. Research histology laboratories and veterinary diagnostic facilities requiring a dependable high-profile stainless steel PTFE-coated blade at 50pcs per box will find the RD-1601B available through Medigear.uk. Contact Medigear.uk to confirm availability, pricing, and supply terms for the RD-1601B.

X46cr13 Stainless Steel for Edge Retention and Corrosion Resistance

X46cr13 is a precision martensitic stainless steel grade used in premium histopathology blade manufacturing, combining the carbon content needed for blade hardness and edge retention with the 13% chromium required for corrosion resistance. The Roundfin RD-1601B blade body is manufactured from this grade throughout.

PTFE Coating for Smooth, Low-Friction Sectioning

The PTFE coating on the RD-1601B reduces friction at the blade-wax block interface during each cutting stroke, delivering smoother sections and reducing the force required per stroke. The coating also minimises wax pick-up on the blade surface, extending section quality across the full service life of each blade and reducing the risk of section artefacts from wax adhesion.

35° Cutting Angle — Standard for Histopathology

The 35° bevel angle is the established standard for routine paraffin and cryostat sectioning. Both the RD-1601B and its low-profile sibling, the RD-1601A, share this angle, providing consistent section quality regardless of which Roundfin blade profile is in use.

High-Profile 80mm×14mm for Compatible Holder Geometry

The 80mm×14mm blade body fits the standard high-profile blade holder geometry used across compatible microtome brands. The 14mm width is the specification for the high-profile format and ensures correct seating in high-profile knife rests without play or misalignment.

0.325mm Thickness for High-Profile Blade Rigidity

The RD-1601B at 0.325mm is thicker than the low-profile RD-1601A (0.25mm), consistent with the greater body rigidity required in the high-profile blade holder configuration. Blade thickness is a fixed specification — confirmed from the Roundfin brochure.

50 Blades per Dispenser Box for Safe Individual Removal

The 50-blade dispenser box format allows one blade to be removed at a time without direct handling of the remaining blades, reducing sharps exposure during blade change. The standard 50pcs/box format supports predictable stock management and reordering cycles.

Proprietary Manufacturing Process for Durability

Roundfin's proprietary process ensures edge quality and durability, supporting faster, acceptable sectioning. This refers to the sharpness and consistency of the cutting edge across the blade's service life from box-fresh through to the end of its effective use.

FAQ

Frequently Asked Questions

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

The RD-1601B is a high-profile microtome blade. High-profile refers to the physical height of the blade body, 14mm width in the case of the RD-1601B. High-profile blades are designed for use in high-profile blade holders and knife rests on compatible microtomes and cryostats. If you are unsure whether your instrument uses a high-profile or low-profile blade, contact Medigear.uk for guidance. The low-profile equivalent in the Roundfin range is the RD-1601A.

The RD-1601B is manufactured from X46cr13 stainless steel. This is a martensitic chromium stainless steel grade with approximately 0.46% carbon and 13% chromium content — the chromium providing corrosion resistance and the carbon supporting the blade hardness and edge retention needed for histopathology microtomy. The X46cr13 grade is a recognised standard in premium histopathology blade manufacturing.

PTFE (polytetrafluoroethylene) coating on the blade surface reduces friction between the blade and the paraffin wax block during each cutting stroke. This results in smoother, more consistent sections and reduces the force required per stroke. PTFE coating also reduces wax pick-up and adhesion on the blade, which helps maintain section quality throughout the blade's service life and reduces cleaning requirements between sections. Roundfin cites the unique coating as a key performance feature of the RD-1601B.

The RD-1601B has a 35° cutting angle. This is the standard bevel angle for routine paraffin and cryostat histopathology sectioning, providing the right balance of sharpness and mechanical durability for high-volume diagnostic tissue cutting. The 35° angle is shared with the low-profile RD-1601A.

The blade body is 80mm long and 14mm wide, with a thickness of 0.325mm. These are confirmed specifications from the Roundfin brochure. The box weight is 150g for 50 blades — heavier than the RD-1601A (100g) due to the greater thickness and different body geometry. Contact Medigear.uk for full shipping and case weight data.

The RD-1601B is the high-profile variant (80mm×14mm, 0.325mm thick, 150g per box) and the RD-1601A is the low-profile variant (80mm×18mm, 0.25mm thick, 100g per box). The RD-1601B is narrower but thicker than the RD-1601A, consistent with high-profile blade holder geometry requirements. Both use X46cr13 stainless steel with PTFE coating and a 35° cutting angle. Profile selection should match the instrument's blade holder. Both are available through Medigear.uk.

Each RD-1601B dispenser box contains 50 blades. The dispenser format allows one blade to be removed at a time without direct contact with the remaining blades. Medigear.uk can advise on case quantities and volume ordering terms.

Yes — the manufacturer confirms compatibility with most microtomes and cryostats. The high-profile format covers the high-profile cryostat blade holder configuration on compatible platforms. Contact Medigear.uk to confirm compatibility with your specific cryostat model before ordering.

Roundfin cites a proprietary manufacturing process as ensuring edge quality and durability for the RD-1601B. The cited outcomes are faster acceptable sectioning and longer blade service life — attributes related to the sharpness, consistency, and durability of the cutting edge from box-fresh through to the end of the blade's effective life.
