The Celsius® Pak Carrier is a mechanical device designed to hold 1L and 2L Celsius® Paks. The Celsius® Paks are mounted on both faces of the Carrier and are attached with stainless steel brackets that were designed especially for the 1L and 2L Celsius® Paks. A total of eight brackets are provided on each face. This Carrier is used for freezing and thawing in the Celsius® FT100. Each freezing chamber of the Celsius® FT100 holds up to two Celsius® Pak Carriers, meaning a complete Celsius® FT100 can hold a total of six Carriers. The TC33 and TC100 Transfer Carts hold up to two and six Celsius® Pak Carriers, respectively.
