This section offers you a simple system of stainless steel well bars, chucks and freezing blocks, kept cold in cryostat, allow you to perform a variety of precision embedding techniques addressing the most difficult embedding tasks with ease and minimum time needed. 20 to 60 seconds needed to freeze (depending on the well size). Multiple samples handled quickly with no monitoring necessary (for placement of heat extractor). Precise flat or on edge embedding, predictable orientation, liquid samples easily embedded and no crush artifact caused by heat extractor weight. Reduce tissue waste with less trimming the result of flat plane of embedding. Minute samples embedding in the same plane.  Less cryostat adjustments necessary, comfortably preformed on a shelf just inside most cryostats. Easy to use and saves time.
