Choosing a Microtome
A rotary microtome is the core instrument in any paraffin histology workflow. It cuts thin sections from paraffin-embedded tissue blocks for mounting and staining. Section quality depends directly on the microtome precision, blade holding system, and specimen advance mechanism.
This guide helps you choose based on throughput, automation, section quality, and budget.
Match the lab tier first
Microtome choice is mostly a throughput and consistency decision. Start with the work volume and operator burden you need to support, then compare features.
Semi-automatic rotary
Research Labs
Best for: Standard research histology with moderate throughput and repeatable section quality
Key features: Motorized advance, specimen retraction, programmable thickness
Fully automated
Core Facilities & High-Throughput
Best for: High-volume core labs, demanding tissue types, and serial sectioning
Key features: Full automation, waste tray, section transfer system, digital readout
Microtome Comparison
Compare the main capability differences before you narrow by supplier preference or budget. These are the specs most likely to change section quality and operator speed.
| Product | Type | Section Range (um) | Automation Level | Specimen Retraction | Blade Compatibility |
|---|---|---|---|---|---|
| Manual Microtome Series | Manual | 1-60 | Manual | Manual | Disposable low-profile |
| Fully Automated Rotary Microtome Series | Fully Automated | 0.5-100 | Full motorized cut cycle | Automatic | Disposable low-profile and reusable |
| AccuSection Rotary Microtome | Semi-Auto / Fully Automated | 0.25-100 | Motorized advance | Automatic | Disposable low-profile and reusable |

Frequently Asked Questions
What is the difference between a manual and automated microtome?
A manual microtome relies on the operator to drive the cut cycle. Semi-automatic systems motorize specimen advance, and fully automated models motorize the complete cut cycle. Automation improves consistency and reduces fatigue when throughput is high.
How often should I change microtome blades?
Disposable blades are commonly changed every 50-100 sections, or sooner when you hear scraping, see compression artifacts, or notice uneven section thickness. Hard tissues usually require more frequent blade changes.
Can I cut frozen sections on a rotary microtome?
No. Frozen sections require a cryostat, which is a microtome enclosed in a refrigerated chamber. Standard rotary microtomes are designed for paraffin-embedded tissue at room temperature.
