Understanding the Aps Nesswell Manual Rotary Microtome

The Aps Nesswell Manual Rotary Microtome allows users to create ultra-thin slices of biological tissues, essential for microscopic examination. This device is designed to provide high-quality sections consistently, making it an invaluable tool for histologists.

Step 1: Unpacking and Setting Up the Microtome

• Description: Begin by carefully unpacking the microtome and ensuring all parts are accounted for according to the manual.
• Practical Tip: Place the microtome on a stable, vibration-free surface to avoid any disruptions during operation.
• Applicable Scenario: Setting up in a quiet laboratory environment ensures optimal performance, especially when dealing with sensitive samples.

Step 2: Preparing the Tissue Sample

• Description: Properly fix, embed, and orient your tissue sample in paraffin or resin to ensure it is ready for slicing.
• Practical Tip: Use the correct embedding media suitable for your specific tissue type to achieve the best results.
• Applicable Scenario: For delicate tissues, using a low-temperature polymer can prevent degradation during the embedding process.

Step 3: Adjusting the Microtome

• Description: Adjust the thickness settings on the Aps Nesswell Microtome to your desired slice thickness, which typically ranges from 2 to 10 micrometers.
• Practical Tip: Start with a thicker section to ensure the blade is properly aligned and working before transitioning to thinner sections.
• Applicable Scenario: When examining hard tissues, such as bone, a thicker section may be necessary to prevent damage to the sample.

Step 4: Cutting the Sections

• Description: Secure the sample in the microtome and proceed to cut sections by turning the rotary handle smoothly.
• Practical Tip: Apply even pressure while rotating the handle to achieve consistent and high-quality sections.
• Applicable Scenario: This technique is particularly beneficial when preparing samples for immunohistochemical staining, where uniformity is crucial.

Step 5: Collecting and Transferring Sections

• Description: Carefully pick up the cut sections using a brush or forceps, and transfer them onto a microscope slide.
• Practical Tip: Use warm water to float the sections, making them easier to handle without damaging them.
• Applicable Scenario: Floating sections in warm water is especially useful for fragile samples, ensuring they remain intact.

Step 6: Staining and Mounting

• Description: Stain the sections using appropriate histological stains and mount them for microscopic evaluation.
• Practical Tip: Always follow standardized protocols for staining to ensure reproducibility and accuracy.
• Applicable Scenario: This is critical when preparing samples for diagnostic purposes, where clarity and contrast are paramount.
