The Leica CM3050 S cryostat features superior user comfort with excellent safety standards for practically all types of cryosectioning applications. Particularly when working 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. Section thickness setting: 0.5 to 300 µm Maximum specimen size: 40 mm x 55 mm Horizontal specimen feed: 25 mm Vertical specimen stroke: 59 mm Specimen retraction: 50 µm Specimen precision orientation: by 8° (x/y/z axis) Trimming (in 6 steps) 5 to 150 ?m ±0.5 ?m in steps of 5, 10, 30, 50, 100, and 150 ?m Motorized coarse feed at two speeds: 500 µm/s, 1.000 µm/s Temperature range: 0°C to -40°C Defrosting: programmable 1 automatic defrost cycle/24 h duration: from 6 to 12 min; manual defrosting Freezing shelf temperature: approx. -45°C at an ambient temperature of 22°C Specimen cooling (optional) -10°C to -50°C (±3K) Defrosting: manual defrosting Power requirements: 240V ~ 50Hz Power consumption: 1800 VA Dimensions: 882 x 766 mm x 1040 (W x D x H) Weight: approx. 180 kg
