[Set of Pink and Blue]

[Blue]

This blue Eppendorf iceless cold pack reliably cools samples for more than an hour at 0 degrees C when precooled for 2 hours at -20 degrees C. Temperature safety is indicated by a color change when temperature is exceeded. The light blue pack turns dark blue when ice cold. The pack returns to its original light blue color when temperatures are above 7 degrees C. The special cone contour prohibits freezing of samples. This space saving cold pack is superior to an ice bath and keeps samples safe from contamination.
