Which instrument is used to produce extremely thin sections (0.5 to 1 micrometer) often referred to as 'semi-thin' or 'thick' sections for light microscopy of resin-embedded tissue?
Show answer and explanation
Correct answer: Ultramicrotome
Ultramicrotomes are used to cut resin-embedded tissues. 'Semi-thin' sections are cut at approximately 0.5–1.0 μm to check orientation and tissue quality before moving to ultra-thin sectioning for electron microscopy.
