Dear colleagues,
we own a Cryo lightmicroscope (Stellaris 8 Cryo-CLEM from Leica) that uses a 25 liter dewar for liquid nitrogen. Sometimes the session ends early and eventually we have a half-full dewar and we cannot re-use the liquid nitrogen anywhere else - either everything else is full or at some instruments we do not re-use nitrogen because of possible contaminations.
We think of blowing it out with nitrogen gas at a very well ventilated area. But this would require room alterations.
Therefore my question to you: How do you dispose of 10-20 liters of liquid nitrogen (that cannot be used anywhere else)? Or are we unique in our problem?
cheers
Tobias
