The CytoTherm CT-4T Plasma Thawer is a laboratory instrument that uses a recirculating water temperature bath with a patented rocking action (US Pat No. 5,779,974) to generate bursts of water flow that agitate both the water in the bath and the contents of the plasma bag. This combination of forces results in a much faster thawing time.

The CT-4T comes with one Corral that will thaw up to 6 plasma bags (450 ml) at a time. A second Corral will let you thaw 6 more plasma bags for a total of up to 12 plasma bags (450 ml) at a time. The operator never comes in contact with the water in the bath when handling the plasma bags. The Corral keeps the entry ports of flat-frozen units out of the water so an overwrap bag is not necessary. The CT-4T comes with a clear evaporation lid and quick-connect drain system that efficiently empties the water bath for easy, convenient cleaning.
