Test
Foam brick ice packs never change shape during freezing, thawing or transit, enabling superior surface contact for more consistent temperature control. Refrigerant bricks are vacuum-sealed for consistent weight and shape.
Cushions fragile shipments, and won’t dilute ice baths or damage samples. Remains frozen longer than regular ice, without the melting mess.
Shock-absorbing polystyrene foam mailers accept sample tubes with rubber or screw caps
