About this item
Primarily designed for the demanding needs of cryosectioning in biomedical, neuro-anatomical and pharmaceutical research.
- Freestanding, motorized open-top cryostat with independent specimen temperature control
- Spacious, easy-to-clean cryochamber with illumination
- Removable heated glass sliding window.
Cryochamber temperature setting down to 40°C in 1° steps. Permanently cooled (down to -45 °C) quick-freeze shelf for 10 specimen discs. Programmable automatic 24-hour defrost cycle. Defrost cycle duration programmable from 6 to 12 minutes. Additional manual defrost feature. Microprocessor-controlled. Foil-protected control panel with locking key to prevent inadvertent changes of programmed parameters. Menu-driven operation in 5 languages (German, English, French, Spanish, Italian) via LCD display. Counterbalanced handwheel, lockable in two positions, for manual sectioning. Locking status indicated on display.
Motorized sectioning: Motorized sectioning operated via control panel and foot switch. Section counter with reset. Sectioning window adjustment. Handle of the handwheel can be centered in motorized operation. Emergency stop switch. 3 sectioning modes: intermittent, single and continuous stroke. 2 sectioning speed ranges selectable: 0.1 - 170 mm/s; 0.1 - 100 mm/s. Additional maximum speed setting of: 210 mm/s.
Specimen temperature control: Specimen head with specimen temperature control. Temperature setting range: -10 °C to -50 °C in 1° increments. Specimen quick-freeze feature. Manual defrosting. Stainless steel rotary microtome (all specifications related to temperature are valid for a room temperature up to 22 °C and a relative air humidity of 60%).
Section thickness range: 0.5 to 300 µm, in 0.5 µm increments from 0.5 to 2 µm, in 1 µm increments from 2 to 10 µm, in 2 µm increments from 10 to 20 µm, in 5 µm increments from 20 to 60 µm, in 10 µm increments from 60 to 100 µm, in 50 µm increments from 100 to 300 µm, X/Y/Z specimen precision orientation of 8°. Specimen retraction: 50 µm Total horizontal specimen feed: approx. 25 mm Total vertical stroke: approx. 60 mm. Programmable trimming: 5 - 150 µm, selectable in 6 discrete steps, in 5, 10, 30, 50, 100 and 150 µm increments. Motorized coarse feed: 500 µm/s and 1000 µm/s.
It is the instrument of choice for all research applications and for advanced clinical cryosectioning needs.
Particularly when working in biomedical, neuro-anatomical and pharmaceutical research with delicate specimens – for example brain samples in neuroscience – the precise specimen orientation and the specimen feed system guarantees reproducible, thin, serial sections of maximum quality.
