5)  Fill the mould so that a meniscus of medium is bulging above the brim. Too much medium is not a 

problem. Too little medium can cause failure of the specimen to anchor to the chuck.  
 

 

 

6)  Place the chuck over the mould as quickly as possible and press it. Place the heat extractor over the 

chuck  stem.  Now  close  PrestoCHILL  cover  and  press  on  countdown  Start  button  and  wait  pre-set 
freezing time. 

 

 

 

 

7)  Take the block out. It will be flat with the paper over the specimen. The entire sample, in case of long 

thin biopsy, or all samples, in case of multiple short biopsies, will be at the same level and specimen 
will  be  visible  through  the  blue  lens  paper  due  to  its  semi-transparency.  Moreover  trimming  will  be 
easier because when the paper goes away, it means that the sample is ready to cut.
