shelleyk482 Posted October 4, 2011 Share Posted October 4, 2011 I ordered an ultra-low thermometer for our plasma freezer that should have been in 30 ml of propylene glycol but when we got it, it was in sand instead. Thinking that the wrong thermometer was put in the box (we verified manufacturer's numbers) we called Cardinal and were told that these now only come in the sand. My question: would this be an appropriate thermometer for Blood Bank freezers? Are the heat transmission properties considered to be the same for sand as it is for frozen products?

Deny Morlino Posted October 5, 2011 Share Posted October 5, 2011 I would suggest making a request for information / validation of performance from the manufacturer. If nothing else your Cardinal rep. should be able to look into the questions you have posted here. My immediate reaction is that the sand will not react to temperature changes in the same was as frozen units. Likely the sand would respond to changes in temperature more quickly than glycol. This may not be all bad as the thermometer would then reflect out of range temperatures quicker that a frozen unit on the "warmer" side of things. Curious to see Cardinal's reasoning and answer to your questions. Let us know if you find anything out. Link to comment Share on other sites More sharing options...
cthherbal Posted January 25, 2012 Share Posted January 25, 2012 We use Streck red spirit, works well. It does require an MSDS. Link to comment Share on other sites More sharing options...
