We provide timers, foam “floaties” and thawing instructions to make preparation and use of our CRYOcheck products easy and convenient. It is critical to thaw frozen CRYOcheck products using a 37 °C waterbath for the time indicated in the instructions. DO NOT thaw CRYOcheck products in a heating block or at room temperature. If you do not have a waterbath, you can make your own using a glass beaker and thermometer—if you’re using this method, the water in the beaker must remain at 37 °C for the duration of the thawing process.
