MICROTOME ACCESSORIES

KS 34 S /R/SL The fast freezing unit KS 34 is designed as table-top unit for the adaptation to a rotary or a sliding microtomes for cryo sectioning of fixed specimen from biology and medicine as well as for sectioning soft plastics, rubber, textile fibres, wood, and other materials.

The unit has an extremely efficient enclosed cooling system which ensures fast freezing-on of specimens, temperature control and defrosting within seconds with minimum handling.

- Fast cooling down to -40°C
- Continuous temperature control from +5°C to –40°C
- Digital temperature display

• KS 34 R (for rotary microtomes)
• KS 34 S  for sliding microtomes)
• KS 34 SL (for sliding microtomes with large specimen stage 100 x 80 mm)

Section Transfer System STS Thin sections of excellent quality are guided via a continuous laminar flow of water from the knife edge into the heated water bath without manual manipulation.

The system consists of a special disposable blade carrier with laminar flow of water between cutting edge and heated water bath mounted directly on the microtome. Immediate section stretching occurs as a result of water surface tension simultaneous with cutting. Paraffin ribbons captured are gently transported via a water bridge and transferred automatically into the water bath. Unwanted sections and trim debris are collected in a separate removable waste tray.

CN 30 Cryo Attachment Cryo-sectioning attachment as additional equipment for the HM 360 CN for sectioning at low temperatures.

• Cryo-chamber and integrated knife carrier, specimen holder, electronic control unit and Dewar vessel with automatic filling system
• Open-top cryo-chamber with LN2 cooled cutting area

• Knife carriers for disposable blades, glass and diamond knives can be used
• Quick change from cryo-sectioning to normal operation and vice versa
• Usable coarse feed range: 12 mm
• Vertical specimen stroke: 40 mm
• Inside dimensions of chamber: 202 x 225 mm
• Outside dimensions of chamber: 260 x 278 mm

Cool Cut Cool idea for your daily needs in histology. The electrical cooled object clamp on the Cool-Cut provides reproducible sectioning conditions by holding the paraffin block within an optimal temperature range.

Even for lengthy sectioning conditions without the need to recool outside the clamp can be provided. The clamp temperature remains constantly approx. 20 K below ambient temperature. The Cool-Cut can be attached to all MICROM rotary microtomes and is available with cassette clamp or standard clamp.

Histo Collimator 220-240V/50-60 Hz. Aligns block-face to the cutting plane of the microtome. Especially useful for the fast cutting of already sectioned paraffin blocks.
