The Erma Type Rotary Microtome is a widely used laboratory instrument in India for histological and pathological research. It is specifically designed for cutting uniform tissue sections as thin as 1 micron.

Key Specifications and Features

  • Section Thickness Range: Typically adjustable from 1 to 25 microns (some advanced models up to 50 microns) in increments of 1 micron.
  • Mechanism: Features a cam-drive mechanism with a ball and flange type object holder for precise specimen centering.
  • Feeding Movement: Total feed excursion is approximately 28 mm.
  • Durability: Usually constructed with a heavy metallic base and a protective cover to house the internal mechanism.
  • Standard Accessories: Often includes three object holders, a razor (typically 120 mm), and a honing stone for maintenance.
  • Section Thickness: Typically adjustable from 1 to 25 microns (μm) in steps of 1 micron each. Some variants may offer ranges up to 30 microns.
  • Operation: Manual rotary control via a handwheel. Rotating the wheel moves the specimen holder vertically against a stationary knife.
  • Core Components:
    • Specimen Holder: Often a ball-and-flange type that allows for precise centering and orientation.
    • Knife/Razor: Usually supplied with a 120mm razor made of high-quality alloy or grain steel.
    • Protective Housing: The internal mechanism is typically encased in a metallic cover (often mild steel or cast iron) to protect it from dust and debris.
  • Construction: Built with a heavy cast-iron base to provide stability and reduce vibrations during cutting.
Standard Accessories
  • A 120mm razor with back and handle.
  • A set of three object holders.
  • A honing plate/stone for knife maintenance.
  • An oilcan for lubrication of the internal gears.
  • A dust cover for the entire machine.
Applications
The Erma-type microtome is widely used in:
  • Medical & Diagnostic Labs: Preparing tissue slides for pathological examination.
  • Education: Standard equipment in medical colleges and biology departments.
  • Industrial Research: Analysis of materials like plastic, leather, textiles, and rubber.
