Do you buy a specific label for them?
I've got a few different labels but I'm not sure the sizes are conducive to wrapping 3ml vials. I think I read that 40mm x 20mm is the ideal dimensions for that task. The labels i have for my D11 are all 0.55" X 1.18" which is like 14mm x 30mm ish. Far from ideal but if I just wanted to get some basic labeling on them to know what's it would certainly accomplish the task.
I'm kind of at a crossroads on which way to go forward. If I need to buy new labels for the D11 would it be better to just get specific labels for freezing vials for my Brother Laser printer or invest that money into a M2 which is probably the ideal device for this purpose.
I assume I'll get the use out of the M2 to feel like I'm getting my money worth over the years to come.
