Quick Release Feather Blade Holder - #527844
Accepts low profile FeatherT blades and allows adjustment of the blade angle centered around the edge of the blade. Has a simple quick-release facility for easier blade changing.
The Quick Release FeatherT Blade Holder enables the cryotomist to use the full length of the blade without waste. Another important feature is that the blade angle can be changed without altering the position of the blade edge since it is at the center of the radius of angular movement. The Quick Release FeatherT Blade Holder can be easily changed for the standard knife holder and vice versa. It is also extremely safe to change a blade because it is inserted from the side into a blade carrier.
It is supplied complete with an anti-roll plate and ten Feather blades.
Lever Release Feather Blade Holder - #527842
This fits into a standard knife holder. It enables a low profile Feather™ blade to be easily and safely changed without removing the blade holder from the knife holder.
Motor Drive (/MR) - #527668
For automation of the cutting process. To provide extremely smooth cutting velocities with continuous or single section operation. It has variable speed and zone control and is particularly useful if ultra-repeatability of sections is critical. It also includes an emergency stop.
Motor Drive (/MRS) - #527664
As /MR above, but with high torque/low speed for very hard specimens, e.g. undecalcified bone.
Foot Switch for Motor Drive (/V) - #527658
Leaves hands free to collect sections.
Motorized Advance Rewind (2 speed) (/MAR) - #527672
Permits rapid rewind of microtome to start position, and rapid, slow or incremental advance (e.g. for trimming). Manual operation is also possible.
All motor-related controls conveniently located in this single control panel
Ultra Violet Light Decontamination Unit (/U) - #527684
Fits into the window aperture, this unit helps decontamination of the cryostat.
OTF5000 Low Version (/LOW) - #527662
Operating height reduced by 10cm from the standard cryostat.
OTF5000 Low Version (/LOWEC) - #527660
Operating height reduced by 10cm from the standard cryostat with dual refrigeration.
Dual Refrigeration
Dual refrigeration is an option available on the basic and LS models and is a standard feature of the HS model.
- There are three main benefits to dual compressor refrigeration:
A dual compressor system can achieve lower chamber temperatures than a single compressor system and will cool down more quickly.
- Compressor usage is shared and this will extend the life of the compressors.
- In the unlikely event of a compressor failure, the remaining compressor will automatically maintain the selected temperature, thus refrigeration will be uninterrupted. A warning light will indicate a compressor failure. This allows 24 hour guaranteed performance.
Dual Refrigeration System (/EC) - #527652
The dual refrigeration switch allows selection of a single compressor or both compressors. When a single compressor is selected the lowest achievable chamber temperature is -35°C. A temperature of -40°C is achievable when both compressors are selected.
Dual Refrigeration System (/LT) - #527666
As /EC but when a single compressor is selected the lowest achievable chamber temperature is -40°C. A temperature of -45°C is achievable when both compressors are selected.
Specimen Quick Freezer (/QF) - #527682
Enables tissues to be rapidly frozen to -80 °C within the cryostat cabinet. (Not available as an option on units with dual refrigeration).
Cryomatic Specimen Temperature Control (/D ) - #527682
It is imperative with some tissues that the blade cutting the tissue is colder than the specimen so that the tissue section is cooled by the blade and anti-roll plate and not warmed up by them, as the latter may result in the section becoming ‘sticky’ and compressed. The Cryomatic Specimen Temperature Control is designed to raise the specimen temperature to any set point above the chamber temperature (+5°C above lowest chamber temperature).
The Cryomatic specimen block is electrically heated, therefore the response to changes of temperature is much faster than if a refrigerant system is used.
