Is one better over the other for general purpose use?
I was looking through VWR catalog and they offer both mercury and red fluid types for the same range for similar price. Usually mercury is more costly, but it's the opposite in this case. They're charging a lot more for yellow back version compared to white back and I think that explains it has to do with inventory/demand than anything.
they're both 1°C division, -20 to 110°C
look at 61066-104. Spirit filled $9.48
look at 61013-028 mercury filled $8.02
