Every Diagnosis Starts With a Perfect Section
Explore the technology inside our tissue processing systems.
The Blade-to-Block Interface Where Diagnosis Is Won or Lost
Every artifact in a pathology report — compression, chatter, thickness variation — originates at the cutting edge. Specimen's rotary microtome chassis is machined from a single billet of 316L stainless steel, eliminating the resonance nodes that cause ribbon irregularities in cast-frame competitors.

Blade Advance Sequence
Sectioning Sequence — What Happens in 0.3 Seconds
- 01Specimen advance — Motorized coarse feed positions block face 3 µm below blade plane.
- 02Blade engagement — Tungsten-carbide edge contacts paraffin at 3° clearance angle, shearing cleanly without compression.
- 03Ribbon formation — Section exits blade face and adheres to previous section via paraffin surface tension — forming a continuous ribbon.
- 04Anti-chatter dampening — Pneumatic isolation base absorbs resonance; chassis geometry prevents harmonic feedback into the cutting plane.

The Sectioning Quality Guide includes 14 pages of ribbon photography, artifact taxonomy, and blade-selection charts for every tissue type.
Reagent Carousel Engineering That Eliminates Carry-Over
Specimen's TP-12 tissue processor runs a 12-station reagent carousel with individual station sensors. Each bath is monitored for temperature (±0.5°C), reagent level, and contamination index — displayed on a 10.1" capacitive touchscreen. When xylene carry-over into paraffin exceeds 0.3%, the system flags the station before the next cassette run.

H&E section at 40× — 3 µm thickness, SM-7 microtome
Section Thickness Determines Stain Intensity. We Hold 3 µm.
Stain intensity in H&E and IHC protocols is directly proportional to section thickness. A 5 µm section where a 3 µm was ordered produces over-stained nuclei that obscure Ki-67 scoring. Specimen's SM-7 holds 3 µm ±0.2 µm across a full 60-cassette run — verified by laser profilometry at the factory.
Intraoperative Diagnosis in Under 8 Minutes, Consistently
Frozen section turnaround time is not just a convenience metric — it determines how long a patient remains under general anesthesia. Specimen's CS-3 cryostat reaches −35°C in 12 minutes from ambient, maintains ±0.5°C cabinet uniformity, and produces artifact-free sections from fresh surgical specimens without pre-cooling.

Every Instrument Speaks Your LIS Protocol
Specimen instruments ship with HL7 v2.5 and FHIR R4 integration modules pre-installed. The SM-7, TP-12, and CS-3 each expose a RESTful API for programmatic control, allowing your LIS to trigger processing runs, query instrument status, and pull QC logs without manual data entry.
Bidirectional LIS Interface
HL7 + FHIRHL7 v2.5 and FHIR R4 — accession numbers flow from LIS to instrument; run data flows back automatically.
REST API Access
REST APIFull instrument control and status query via documented REST endpoints. Python and R SDK available.
QC Log Automation
ISO 15189Every run generates a tamper-evident QC log in PDF/A format, automatically filed to your document management system.
Multi-Site Dashboard
Multi-siteReference laboratories operating 3+ sites view all instrument status, reagent levels, and throughput from a single web dashboard.

"We replaced two aging Leica microtomes with the SM-7 last quarter. Ribbon consistency improved immediately — our histotechs noticed within the first block. The 3 µm hold across a full cassette run is exactly what the spec sheet claims."
Dr. Patricia Holloway
Laboratory Director
Northwell Health Pathology
"The TP-12's xylene carry-over alert has already caught two reagent contamination events we would have missed. That's two patient cases that didn't have to be re-processed. That's the ROI conversation I needed for my department head."
Marcus Okonkwo, HT(ASCP)

"Comparing throughput specs across seven vendors took three weeks. Specimen was the only manufacturer that provided laser profilometry certificates for section thickness verification. That level of documentation closes procurement reviews faster."
