Roundfin TR-302 Paraffin Trimmer

NHS histopathology departments, hospital pathology laboratories, and diagnostic services that require a dedicated paraffin trimmer for the pre-microtomy tissue block preparation stage are the primary procurement context for the Roundfin TR-302 Paraffin Trimmer. Before tissue blocks can be sectioned on the microtome, excess paraffin wax is routinely trimmed from the cassette base and block face to expose the tissue and allow the microtome to cut cleanly. The TR-302 provides a fixed 85°C-heated surface for this trimming stage, with a grooved aluminium alloy construction that channels waste wax directly into the built-in 300ml collection drawer. Medigear.uk supplies the TR-302 and can provide NHS procurement documentation.

Medical colleges, university histology teaching departments, and training laboratories benefit from the TR-302's simple, single-function design, which provides a dedicated, safe, and hygienic paraffin-trimming station for student use without the complexity of temperature adjustment. The fixed 85°C surface temperature and 5–8-minute preheat time establish a consistent daily starting point for teaching histopathology workflows. Medigear.uk can advise on TR-302 configuration for teaching procurement.

Research histology laboratories, food testing services, and private pathology facilities requiring a compact, lightweight paraffin trimmer that can be positioned on any laboratory bench — adjacent to the microtome or embedding station — will benefit from the TR-302's 1.95kg weight and L285×W160×H120mm footprint. At 50W, the TR-302 draws minimal electrical power and can be operated from any standard bench socket. Medigear.uk can advise on the procurement of TR-302 for research and private settings.

Veterinary diagnostic laboratories, commercial histopathology services, and forensic pathology departments requiring a reliable, waterproof, and heat-resistant paraffin trimmer with a built-in wax waste management system will find the Roundfin TR-302 available through Medigear.uk. The dual voltage AC 220V/110V specification supports international deployment. Medigear.uk can discuss TR-302 supply terms on request.

Tilted Aluminium Alloy Surface with Grooves for Clean Wax Drainage

The tilted grooved aluminium alloy heating surface channels excess trimmed wax continuously toward the built-in collection drawer, preventing wax pooling on the work surface during a full session of block trimming. This self-draining design significantly reduces surface cleanup time compared to flat-surface trimmer designs, in which wax accumulates across the heating area during use.

Built-In 300ml Wax Collection Drawer

The integrated 300ml wax collection drawer captures all waste wax drained from the heating surface, containing it in a single removable tray for convenient end-of-session disposal. The built-in design keeps waste wax off the laboratory bench and provides a full-session waste management solution without requiring separate trays, liners, or improvised collection containers.

Fixed 85°C for Immediate Ready-to-Use Operation

The fixed 85°C surface temperature eliminates the need for temperature selection and adjustment at the start of each session — the TR-302 is ready to use after the 5–8-minute preheat with no further operator input. For laboratories with consistent daily paraffin-trimming protocols using standard wax formulations, the fixed 85°C setting provides a reliable, repeatable operating condition without the risk of incorrect temperature settings.

5–8 Minute Preheat for Rapid Session Start

The 5–8-minute preheat time from a cold start allows the TR-302 to be switched on at the beginning of the working session and to reach full operating temperature quickly — before the first blocks are typically prepared for sectioning. The fast heat-up means minimal waiting time at the start of the histopathology preparation workflow.

Lightest Instrument in the Roundfin Histopathology Range

At 1.95kg, the TR-302 is the lightest instrument in the Roundfin catalogue — lighter than the most compact slide dryer (XH-2002 at 5kg), lighter than the most compact tissue bath (FL-220 at 5.45kg), and lighter than any microtome or combination instrument. This weight makes the TR-302 easy to position on any bench space adjacent to the microtome and simple to relocate between workstations without assistance.

Waterproof, Well Insulated, and Heat Resistant

The waterproof, insulated, and heat-resistant construction makes the TR-302 suitable for use in the histopathology laboratory environment, where water baths, cleaning solutions, and chemical reagents are routinely used nearby. Waterproofing prevents ingress damage from incidental liquid contact, and heat resistance protects the outer surfaces during the working session.

Low Centre of Gravity with Ergonomic Handles

The low centre-of-gravity design, combined with ergonomic handles, prevents the instrument from tipping during the paraffin block contact step, in which the operator applies brief, firm downward pressure to the block face on the heating surface. The stable, low-gravity platform and secure handles support confident, controlled operation throughout the trimming session.

50W Low Power for Any Laboratory Socket

At 50W, the TR-302 can be operated from any standard laboratory bench socket without requiring a dedicated high-capacity supply. The low power draw makes it practical to operate alongside other bench instruments on standard circuit configurations.
