Selecting the Right Knife for Cutting Paraffin Embedded Sections
Which knife is recommended for cutting paraffin embedded sections on a rotary microtome?
1) Disposable knife
2) Steel knife
3) Tungsten carbide knife
4) Diamond knife
Final answer: Option 1
Answer:
In cutting paraffin embedded sections on a rotary microtome, the recommended knife is a disposable knife.
When cutting paraffin embedded sections on a rotary microtome, the recommended knife to use is a disposable knife. Different knives have specific applications and the disposable knife is preferred for this procedure due to its sharp and precise cut, as well as its cost-effectiveness.
Although steel and tungsten carbide knives can also be used, they require honing and extra care that can make the process more time-consuming and challenging. The diamond knife is usually reserved for extremely thin cuts (ultramicrotomy) and is not typically used with paraffin embedded sections.
