Key Features

OTF6000-Product-Feature-Image-01 microtome

The Microtome

The OTF7000 Cryostat includes a new 5050 interchangeable knife block. This allows the user to quickly and easily change between the solid knife block that accepts many different types of knives including tungsten carbide tipped knives and the QRFBH that accepts Feather™ disposable blades.

The 5050 microtome is available:

  • With or without specimen orientation and can cut sections between 1μm and 60μm thick.
  • With an Easi-Set anti-roll plate which enables the simplest possible set up. This reduces preparation times to an absolute minimum.
OTF6000 Cryostat Control Panel


The OTF7000 cryostat comes with a wide range of features that increase versatility and widen the scope and use of the microtome. These include:

  • Manual control
  • Motorised drive, facilitating powerful, extra slow cutting that’s free from vibration. This allows easy and precise repeatability of sections.
  • Motorised advance/ rewind as standard with two speeds for accurate and rapid alignment of the specimen to the knife.
