Freezer Packs

What are savENRG® Freezer Packs?

savENRG® Freezer Packs are manufactured using a water-based phase change material (PCM). This material solidifies as the surrounding temperature drops from 0°C to -15°C (32°F to 5°F) releasing heat and then melts as the temperature rises from -15°C to 0°C (5°F to 32°F) absorbing heat.

Why are savENRG® Freezer Packs better than a standard cold pack?

savENRG® Freezer Packs work best in the range of -15°C to 0°C (5°F to 32°F) while standard cold packs work best in the range of -5°C to 5°C (23°F to 41°F).

When a standard cold pack is used to keep a product frozen below 0°C (32°F), the product generally reaches its destination cold at best, but not frozen.

savENRG® Freezer Packs safely keep a product frozen below 0°C (32°F) and can be charged in the same residential freezer as cold packs.

When to use savENRG® Freezer Packs:

Embryo biopsy samples for preimplantation genetic testing (PGT) collected at a fertility facility are generally frozen to -20°C (-4°F) after collection and need to arrive frozen below 0°C (32°F) to a diagnostic laboratory. These specimens are shipped overnight using a courier service and have a high likelihood of exposure to extreme ambient temperatures. Use of frozen Cold Packs can increase the risk of specimen thawing before arrival. The sample can be rejected if it arrives cold but not frozen at room temperature. PGT kits equipped with savENRG® Freezer Packs ensure that the embryo biopsy samples arrive frozen at the laboratory.

Features of savENRG® Freezer Packs:

  • Environmentally safe non-toxic water-based product
