This equipment specially designed for the sectioning of samples that have been treated with paraffin, allow the cutting in extra thin layers, which facilitate observation in the microscopy, there are different models of these equipment that perform special cuts; where the angle of the blade and the direction of the cut prepare the samples to be examined with quality.

They are used to obtain fine serial cuts from tissues included in paraffin blocks for subsequent microscopic analysis; we can find from the mechanical microtomes to the more advanced ones, which are laser microtomes; the most modern allow cuts of a thickness of 0.1 to 100 ยตm. we at KALSTEIN offer you the necessary advice through our online channels, where engineers and technicians will answer your questions.

Types of microtomes and how they work.

Sliding microtomes:

  • Fixed sample-subject.
  • Knife fixed on a slider.
  • During cutting the blade is pressed through the sample.
  • Cut thickness from 1 to 60 ยตm
  • Guarantees a stable cut.

Rotation microtomes:ย 

  • Mobile sample-holder.
  • Fixed knife.
  • Powered by a steering wheel.
  • The subject-sample moves downward.
  • Samples accumulate on the blades.
  • It allows to prepare samples between 1 to 60 ยตm.
  • Guarantees a uniform cut.

Freezing microtomes:

  • Sub-category of rotating microtomes.
  • The sample is in a frozen container, for example nitrogen.
  • High hardness of the sample due to temperatures.

Ultra microtomes:ย ย 

  • Extremely fine preparations.
  • Special knives and a very fine advance.
  • Advanced powered by thermal expansion.
  • Cut thickness from 10 to 500 ยตm.

Laser microtomes:ย 

  • They use special laser for cutting.
  • Strong focus and very short impulse durations.
  • It does not cause thermal damage to the test material.
  • Cuts of thickness between 10 and 100 ยตm.
