Hi Julia, We purchased a 21 cu. ft chest freezer from K2 Scientific last year, model K22145-C. It goes down to -40 and has been great so far.

Learn why this is important<https://aka.ms/LearnAboutSenderIdentification> Hello Pest-listers - Does anyone have a -40 ultracold chest freezer purchased in the last 5 years that they like and could provide a spec for? Or if not a specific model, a manufacturer that you have found reliable over that or a longer period of time? We have a walk-in freezer that we have used for many years; this will be a supplemental unit. A couple specific models are mentioned in older posts, but I haven't found recommendations from firsthand experience: * SO-LOW CHEST STYLE FREEZER TO -40ºC MODEL CH40-22 https://www.so-low.com/content/data/product/spec_sheets/CH40-22.pdf * Thermo Fisher Scientific Revco(tm) CxF Series -40°C Ultra-Low Temperature Chest Freezer https://www.thermofisher.com/order/catalog/product/ULT2050-10-A Thanks very much!
