We trialled one of the Barkey's at our lab in the UK (supplied via Labcold in the UK). Not only was it the smallest footprint available that I could find on the UK market but it also did a very good job. Price wise it was comparible to most competitors and we were thawing 4 bags of UK size plasma (approx 230 mls per bag) in 18 minutes. We had no leakages during our trial and we were not dissapointed in the kit. I am looking to replace my thermogenesis plasma thawer which is 10 years old and the Barkey will be right up there for consideration. Hope this helps Dan
