ROTARY MICROTOME FOR HIGH-PERFORMANCE MOTORISED AND MANUAL SECTIONING

These rotary microtomes incorporate many evolutinary advances over earlier, well designed and proven manual microtomes. They have a durable and reliable mechanism, some instruments have been motorised while others are microprocessor controlled, to offer ultimate versatility, efficient operation and convenience.


People at ProSciTech have an abiding interest in microscopy, even predating this business which was formed in 1979. Our interest is shown in our small collection of six antique microscopes and two microtomes. The pictured antique microtomes on this page are contrasted against current, best technology and construction Chinese made microtomes. Some of the antique microscopes are shown in images on page O9.


Microtome knives have been largely replaced by disposable blades (see page U1). Most microtome designs now only allow for high and low profile blades to be mounted in a supplied holder.


If you require a tungsten carbide knife for bones and similar hard or tough materials a special tungsten carbide knife is needed, but modern microtomes with the tall blade holder have forgotten about this need. Our two manual microtomes may be ordered with a blade holder in the shape of traditional microtome knives ‐ see the holder on our page U1. This blade holder is removable and may be replaced with a conventional permanent steel knife or a tungsten carbide knife.

MANUAL ROTARY MICROTOME

This microtome has been designed for effortless manual sectioning using a counterbalanced, exceptionally smooth‐running hand‐wheel. Storage space on top of the instrument housing provides room for sectioning tools and accessories. This microtome features a low‐maintenance micrometer feed system. The vertical cross‐roller guides are backlash and maintenance free. A horizontal specimen feed via a precision cylinder guide system.

Features

  • Streamlined ABS body for easy cleaning
  • Trimming button for easy switching between trimming and cutting mode
  • Specimen retraction function protects specimen from blade damage

  • Easily lubricated and maintained
  • Smooth blade movement and rotation of hand wheel
  • Disposable blade can move horizontally to avoid danger of contact with the blade
  • Waste tray collects sectioning debris, easily removable for cleaning
  • Adjustable specimen clamp base for quick exchange of cassette clamp and pincers clamp
  • Specimen orientation on X/Y axes 8°
  • The large 70mm vertical stroke allows sectioning of super mega cassettes and also supports safer specimen changing due to the greater distance to the knife edge.
  • Efficient trimming function ‐ by activating the mechanical trimming function, the specimen advances towards the knife in a predefined step of 30ìm, which provides an efficient method of trimming specimen blocks.
  • Specimen retraction prolongs the life of the cutting surface, facilitates consistent sectioning and eliminates the build‐up of debris on the back of the knife or blade.
  • Coarse adjustment ‐ positioned closer to the user for ease of use.

CRYOSTAT

WITH UV STERILISER & INDIVIDUAL TEMPERATURE CONTROLS

This freezing microtome, also known as a cryotome, is designed for the optimal production of cryo-sections from most animal and plant tissues. Most frequent use is by pathology laboratories, but also many research facilities require a cryostat.

This automated cryotome has a UV source which is used for 35 minutes to sterilise the instrument and specimen off-cuts. Another special feature is the capability to operate different parts of the instrument at varying temperatures. This facilitates sectioning and especially reduces ice crystal condensation on specimen and knife by using a lower temperature on surrounding parts.

The equipment contains the following main components:

  • Some of the panels are under computer control; showing temperature and working conditions.
  • The middle of the unit contains to the low-temperature unit for quick freezing of biopsy tissue and section cutting operations
  • The lower part of the unit holds the refrigeration compressor unit
  • Behind the low-temperature unit holds the mechanical drive and motor drive units.

Features

  • Control System: automatic temperature is computer-controlled. The LCD displays three temperatures. Shown are the working conditions of all hardware, including compressor A, compressor B, lighting, UV, defrost and advance and withdrawal of the motor, freezing of the table and the knife. The instrument has a count-down display when the compressor is started.
  • Four freezing points: the dual-compressor control system has four thermostat control points - the head, knife, table and box. The head can be set to different sectioning temperatures.
  • Freezing speed: there is no need to pre-cool, the instrument can get into freezing mode after only 10 min from start up. It can be switched off after finishing work to save power.
  • Operating temperature: The cryostat sections well without using very low temperatures. This saves energy and time and also reduces ice crystal condensation. A hard matrix achieved by a lower temperature may be required for hard specimens.
  • System protection: The rapid freezing system can be switched off manually at any time. After working 8 hours, the rapid freezing system will switch off automatically.
  • Defrosting system: it has automatic and manual defrosting functions and 1) defrosting time interval; 2) defrosting time; 3) manual defrosting may be set. These settings may be varied according to ambient temperature. The defrosting function can be switched off any time; the instrument will change to freezing mode after the defrosting function is switched off.
  • Mechanical design: The instrument's mechanical construction is superlative . The use of roller bearingsmakes the instrument very stable in the vertical plane. The mechanism is enclosed and maintenance-free. Mechanical performance is excellent for the production of uniform flat and stable section; a fine anti-curling function is provided.
  • Sterilisation: This cryostat has a UV disinfection function, and the freezing box is designed for easy cleaning of sectioning debris.
  • Tissue endothermic device: It can freeze tissue rapidly using the freezing table.
  • The big freezing table is suitable for hospitals.
  • Steel knives and disposable blade holders are interchangeable.
  • Thin or thick sections can be prepared outside the box.
  • Knife movements control advance, retraction and sectioning speeds.
