Buying a Research Microtome: Why Quality Matters in Research Microtomy

What happens when murky data results from variability in microtomy techniques?

Improper instrument selection or configuration and an unclear understanding of what type of sectioning the lab will be doing can lead to delayed results or poor-quality data. Delays such as these can cause a ripple effect for investigators, threatening result credibility. Leica Biosystems can help optimize your sectioning workflow, allowing users of all experience levels to choose their sample parameters and enhancing sample adequacy.

Important Considerations for Research Microtomy
It is important to consider two key factors when preparing your research laboratory to perform microtomy. The first key consideration is determining what sample sources your research requires is critical to choosing the right microtome for your applications. The second key consideration is defining and using the proper microtome configurations to ensure downstream sample adequacy.

Choosing the microtome that lets you get the best possible section from every block and broadens your research with a wide selection of blade and specimen holders enables you to discover breakthroughs in research for biomedical to industrial applications.

There are three challenges researchers face when adding microtomy into their research laboratory:

1. Identifying the application type and kind of materials used for the research project
2. Understanding what type of microtome is needed for their research
3. Knowing how to configure the microtome for optimal use properly

Considerations for choosing a microtome
Applications
Knowing what type of application your research requires is a first step to understanding what type of microtome will be the best fit for your laboratory.

First, define the purpose of the experiments and the type of specimen to be cut in your research plan. What goal or problem do you wish to solve by cutting a material?

Second, determine the density and thickness of the materials to be sectioned; will they be soft, like those of tissue in paraffin, hard, like bone or teeth in resin, or plastic materials used in manufacturing?

Third, having clear parameters on the purpose of the experiment, specimen, and type of material you plan to cut will help determine the correct knives, blades, and angle to use; options include Fixed or disposable metal, glass, and diamond blades.

Manual, semi-automatic, or fully automatic rotary microtomes?
Each element of choosing the type of microtome needed in your laboratory has its merits.

A manual microtome uses a specimen feed and cutting stroke (or rotary motion of the wheel) that is managed by hand. It also has a lower throughput, but this is not always detrimental. The ability to manually cut and evaluate each section offers microtomists the opportunity to concentrate on each block and section with greater control over the cutting process. The ability to assess in real time provides potential time savings through consistency. Still, this option requires a more significant amount of vigilance on behalf of the user to maintain quality standards.

A semi-automated microtome uses a specimen feed that is motorized, but the rotary motion of the handwheel is still done manually and offers a medium throughput. The semi-automated method works well for thick and hard sections, using a consistent force when cutting through a block. Automating the specimen feed provides the precision of a motorized specimen feeding that yields consistent, reproducible sections.

A fully automated microtome has both specimen feed and rotary motion of the handwheel automated, contributing to the ability to produce high-throughput sectioning. The mechanization of the instrument allows for automated setting and correction of feed movement and knife cutting. In addition, automation also provides consistency from user to user, so it can speed up time and provide reproducibility of sectioning. Many fully automatic microtomes allow for cutting a more comprehensive range of thicknesses, providing researchers flexibility when choosing sectioning materials such as paraffin or resin-based fillers.
