Abstract
A cooler assembly for maintaining vials filled with enzyme samples in a chilled state. The cooler assembly includes a foam block having wells disposed therein for holding vials of samples in an upright position. The cooler assembly also includes an outer foam box and a lid. The foam block is positioned inside the outer foam box. The lid is then positioned on top of the outer foam box to provide further insulation for the foam block. In use, the foam block is filled with a liquid, such as water, via a fill hole. The foam block is then frozen. Vials are placed in the wells of the frozen foam block so that the contents of the vials remain cool when placed in a room having an ambient temperature. The inner foam block is made from self-skinning, open cell foam. The skin on the foam block renders the block leakproof. The cooler assembly provides for efficient heat transfer between the chilled wells of the foam block and the contents of the vials.
