Hi, I want to store nasal polyp samples for researching. Everyday we have 4 samples and I should send them to Switzerland from Wiesbaden, Germany, but All in all we have 50-100 samples, which one do you suggest? 6L or 10L? however the 10L tank may also keep the low temperature for longer times? How many samples I can store in each of them? For how long?
Best regards,
