Precision BioLogic is registered with the FDA and our CRYOcheck medical devices are listed with the FDA as part of our registration. Registration and listing provides the FDA with the location of medical device establishments and the devices manufactured at those establishments. Knowing where devices are made increases the United States’ ability to prepare for and respond to public health emergencies.

We’ve been developing our integrated line of high-quality, frozen controls, calibrators, and reagents - the?CRYOcheck brand - since 1992. In our effort to expand our product base, we’ve since introduced in vitro diagnostic products.

To ensure product integrity, our standard shipping days are Monday to Wednesday. All of our?CRYOcheck products are packaged on dry ice in Styrofoam boxes and couriered overnight. We include a temperature indicator tag in each shipment to ensure that the temperature in the shipping container has not risen to a level that could compromise the products. We also carefully track all shipments while in transit and notify you once?your order has arrived.
