IsoFreeze® racks contain an inert, non-toxic, color-changing gel that maintains a temperature of less than 4°C for almost 4 hours (with lid on rack) at room temperature. Upon reaching 7°C, the rack alerts the user by undergoing a distinct color change from green to yellow or purple to pink. An ideal combination of function and utility, these racks can go from freezer to lab bench without having to transfer samples.
Maintain sample temp less than 4°C for up to 4 hours*
• Contrasting colors indicate safe sample temperatures at a glance.
• Patented color-changing material indicates when samples are approaching 7˚C
