Cryostat sectioning. With this angled tip the brush meets the tissue flat like a broom because the brush is held at an angle. Sections for staining and microscopy can be prepared immediately using a cryostat microtome. The pathologist armed only with a few jars of stain and a cryostat is asked to steer the course of a patient s surgery based on a small sample of tissue this formidable task is a sharp taste of reality.

Take your time and it will pay dividends at the cryostat when section and under the microscope for review. With the added benefits of all day operator comfort and research specific features leica research cryostats let you make critical discoveries sooner. The cryostat is available in a small portable device weighing less than 80 lb 36 kg to a large stationary device 500 lb 230 kg or more.

Problems while freezing the tissue. The speed and versatility of leica research cryostats help you cut more sections and analyze more specimens each day. If your tissue is coming out smudged or almost smashed not smooth at all then you need to check the temperature of the cryostat head.

For research applications particularly with the brain the tissue is often fixed initially with a formaldehyde solution prior to freezing and cryostat sectioning.

Designed for both research and clinical laboratories the thermo scientific cryostar nx70 cryostat offers innovative design a form fitting shape for user comfort and excellent sectioning quality. The entire histologic laboratory can be carried in one portable box making frozen section histology a possible tool in primitive medicine. The cracking is probably due to over freezing.
