Morning folks, we are trying to get some extra freezing done as we have lost time due to the Covid epedemic.
Has anyone got any research on thaw times for freezing they are prepared to share? At the moment we have a rather long return to ambient from -35c / -30c primarily to allow the objects to thaw slowly and prevent thermal shock but would like the option to reduce this both in our manual operation and to change our computer settings. Note we do not open the freezer and handle the objects whilst frozen as a precaution due to potential embrittlement. our current programme is this 48 hours to reach -35c (or more if not met) 72 hours at -35c to treat 41 hours to defrost/thaw Any thoughts on this would be appreciated many thanks Adie Adrian M Doyle is currently working from home but is available via e mail on ado...@britishmuseum.org Adrian (Adie ) Doyle Integrated Pest Manager Department of Property and Facilities Management British Museum London UK -- You received this message because you are subscribed to the Google Groups "MuseumPests" group.
