May 21, 2015—Milestone Medical is offering a product dubbed PrestoChill for the cryoembedding for high-quality frozen sections. Using the product can speed production of optimally prepared specimen embedded cryostat chucks without freezing artifiacts in 60 seconds, company says.
PrestoChill is an all-dry system, with no use of liquid nitrogen, CO2, or Isopentane. To eliminate potential formation of ice on the freezing platform, an automatic defrost cycle is provided. It consists of a heater embedded in the freezing platform and a vacuum pump to extract water vapors from the chamber. Vapors are condensed and collected in a cold-trap placed in the front of the unit for easy handling. A HEPA filter is provided on the exhaust side of the pump. Integrated software can set the defrost cycle to take place during off hours, then automatically, restart the cooling cycle at a preset time to ensure availability for the first case of the day.
