Rotary Microtome for high-Performance Motorized and Manual Sectioning

These rotary microtomes are adaptations of a well designed and proven manual microtome. The durable and reliable mechanism has been motorised and is microprocessor controlled, offering ultimate versatility, efficient operation and convenience.

We had an abiding interest in microscopy predating ProSciTech which was formed in 1979. Our interest is shown in our small collection of three antique microscopes and two microtomes. The antique microtomes are shown with modern versions on this page contrasted with very modern, Chinese made microtomes of best design and construction. The antique microscopes are shown in two images on page O9.

MANUAL ROTARY MICROTOME
This microtome has been designed for effortless manual sectioning using a counter-balanced, exceptionally smooth-running handwheel. Storage space on top of the instrument housing provides room for sectioning tools and accessories. This microtome features a low-maintenance micrometre feed system. The vertical cross-roller guides are backlash and maintenance free. A horizontal specimen feed via a precision cylinder guide system.

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 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. Also ice crystal condensation is reduced. 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: There are automatic and manual defrosting functions. It can set 1) Defrosting time interval; 2) Defrosting time; 3) Manual defrosting. Time intervals may be set 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 is of a superlative mechanical construction. The instrument is vertical very stable due to the use of roller bearings. 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.
