Frequently Asked Questions
A microtome machine is a precision biochemistry instrument utilized for cutting samples, whether organic or inorganic, into ultra-thin sections known as "sections." These sections are then affixed to slides and scrutinized under a microscope. Widely employed in clinical and research laboratories, microtomes serve pivotal roles. Clinical laboratory personnel employ them to prepare patient samples for diagnostic procedures such as biopsies, whereas researchers utilize them to slice samples from various organisms like lab rats and plants for thorough analysis.
Types of Microtomes:
Rotary microtome: They stand out as the most prevalent type, specifically designed for sectioning paraffin-embedded tissue samples ranging from 0.5µm to 60µm. It operates with simplicity, comprising a weighted handwheel, sample chuck, and blade assembly. Microtomy is executed by rotating the handwheel clockwise; with each revolution, the sample progresses to the blade, undergoes sectioning, and retracts on the upward stroke to prevent any potential damage. Notably, many rotary microtomes are equipped with motorized sectioning capabilities and foot pedals, simplifying the process for users. By simply stepping on a pedal, automatic sectioning can be initiated, alleviating user effort and ensuring uniform sectioning results consistently.
Sliding microtomes: They are known for their versatility, are widely used for sectioning various samples, including those typically handled by rotary microtomes. They offer the added capability to section hard materials like wood with suitable blades. These microtomes come in diverse sizes, ranging from compact units to large industrial models capable of sectioning items several feet wide. Sections typically range from 1µm to 60µm in thickness. The blade of a sliding microtome is affixed to a slide, moving along it to reach the fixed sample holder. With each pass, it sections off a layer of the sample. This straightforward design contributes to the longevity and ease of maintenance of sliding microtomes.
Saw microtomes: They specialize in sectioning hard and brittle samples like bone, teeth, and wood, making them invaluable tools in biological, environmental research labs, and forensic procedures. In operation, samples are positioned against a spinning blade recessed within the unit, with some featuring diamond blades for precise cuts even in the toughest materials. To prevent overheating, a low-pressure water jet continuously flows onto the blade edge as it spins. Unlike other microtomes, saw microtomes produce thicker sections, typically not thinner than 30µm. This specificity in section thickness suits their purpose in handling robust samples effectively.
Vibrating microtomes: They are tailored for sectioning soft and fresh samples, preserving their cell morphology without wax embedding. Common applications include brain, nerve, and spinal cord tissue. Vibrations aid in sectioning by reducing the pressure needed, minimizing the risk of sample fracture. Sections from fresh samples are usually over 30µm thick, while those from fixed samples exceed 10µm in thickness.
Laser microtomes: They provide non-contact microtomy, preserving sample cell morphology crucial for certain applications. Unlike traditional methods, laser microtome doesn't require sample preparation, allowing cutting of samples "in their native state," saving time and resources. As they don't utilize razor blades, laser microtomes can slice various sample types, from bone to soft tissue, with ease.
Ultramicrotomes: They are specifically engineered to create sections for transmission electron microscopy (TEM). To facilitate TEM analysis, these sections must be thinner than 150 nm, significantly finer than the 30µm sections typical of other microtomes.
