Has anyone had any problems with plasma defrosters (microwaves) causing fibrin in the bag? We are see chunks of fibrin in a lot of returned units and the segments have a lot of fibrin in them. Thanks for your feedback.

Is it really fibrin or is it denatured protein caused by overheating?

It does not look like the typical "egg drop soup" fibrin to me. It looks almost chunky and the segments look like they are all clumped up and maybe some of the clumps have fallen into the unit. So I supposed it could be denatured protein, what does that normally look like?

Hi,

Don't personally use the microwaves. But, have heard of similar issues. You may be better off looking at something like a Helmer Plasma Thawer. They seem dependable and have decent thaw times.
