Both sledge microtomes and rotary microtomes are designed to prepare tissue sections for microscopic analysis, but they are typically used for different specimen types and laboratory applications.
In general:
The right choice depends on the type of samples your laboratory processes, the level of precision required and your workflow requirements.
Bright Instruments Rotary Microtome 7010
A rotary microtome is one of the most widely used sectioning instruments in histology laboratories. The specimen is advanced towards a stationary blade using a rotating handwheel mechanism, allowing operators to produce precise and repeatable tissue sections.
Rotary microtomes are commonly used for paraffin-embedded tissue and routine histopathology workflows where consistency and efficiency are important.

A sledge microtome uses a different cutting mechanism in which the specimen passes through a stationary blade. The specimen is mounted on a carriage that slides along precision rails, giving the instrument its “sledge” name.
This design makes sledge microtomes particularly suitable for larger, harder or more challenging specimens that may be difficult to process using conventional rotary microtomes. The increased stability and controlled movement make them well suited to specialist research and laboratory applications where precision is essential.
For laboratories working with frozen specimens, the Bright 8000 Sledge Microtome can also be paired with the Bright Solid State Freezer, enabling accurate frozen sectioning for applications that require low-temperature specimen preparation.

Bright Instruments Sledge Microtome 8000
Rotary microtomes are often the preferred choice when laboratories require efficient, repeatable sectioning for routine tissue processing.
In our experience, laboratories processing large numbers of paraffin-embedded specimens typically prioritise workflow efficiency, ease of operation and consistent section quality.
These factors make rotary microtomes particularly suitable for histopathology laboratories, teaching facilities and routine research environments.
Sledge microtomes become particularly valuable when working with larger specimens or materials that may be difficult to section using traditional rotary systems.
We’ve found that laboratories involved in specialist research often value the additional stability and flexibility offered by sledge microtome designs when processing challenging specimens.
The decision is not necessarily about which system is better overall, but which system is most appropriate for the specimen being processed.
Not every laboratory needs to choose between a sledge and rotary microtome.
If your workflow focuses exclusively on frozen tissue sectioning, a cryostat may be a more appropriate solution. Similarly, laboratories working with whole organs or large neurological specimens may require dedicated sectioning systems designed specifically for those applications.
The most suitable equipment will always depend on your laboratory’s workflow, specimen type and research objectives.
When selecting a microtome, laboratories should consider:
In our experience, understanding the specimens being processed is often the most important factor in selecting the right sectioning equipment.
Choosing the right microtome can have a significant impact on workflow efficiency, section quality and long-term laboratory performance.
Whether you’re evaluating a rotary microtome for routine histology or a sledge microtome for specialist applications, our team can help identify the most suitable solution for your requirements.

What is the difference between a sledge microtome and a rotary microtome?
A rotary microtome advances the specimen vertically through a stationary blade, making it well suited to routine paraffin sectioning. A sledge microtome moves the specimen horizontally through a stationary blade on a sliding carriage, providing greater stability for larger, harder or more challenging specimens.
What is a sledge microtome used for?
Sledge microtomes are commonly used for larger, harder or more specialised specimens that require additional stability during sectioning. When paired with a Solid State Freezer, a sledge microtome can also be used for frozen specimen sectioning.
What is a rotary microtome used for?
Rotary microtomes are widely used for routine histology and paraffin-embedded tissue sectioning.
Which microtome is best for routine histopathology?
For most routine histopathology workflows, rotary microtomes are generally the preferred option due to their efficiency and ease of use.
Can laboratories use both types of microtome?
Yes. Many laboratories use different sectioning systems depending on the specimens and applications involved.
