[Histonet] pouring of liquid nitrogen into a cryostat

[Tony Reilly]

Hi Louise
 
Not a very safe practice.  I have heard of people using a bag of dry ice pellets rested against the knife holder to lower the temperature of the knife, both for when the chamber is too warm or the tissue needs to be cut at a lower temperature, such as fat.
 
regards
Tony

bad idea - what about splash ups from the chamber? Very scary to contemplate
