Size guide

The Dia-Cool is an insulin cooling pouch designed to keep insulin pens, vials, and other temperature-sensitive medications cool for 48 hours or more, depending on the ambient temperature. Available in 8 different sizes, Dia-Cool ensures your medication remains safe and effective. Choose the right size based on how many pens or vials you need to store.

Choosing the Right Size

To select the correct Dia-Cool size, consider the number of pens or vials you need to store:

  1. Decide how many insulin pens or vials you would like to keep in the pouch.
  2. Measure the longest pen or vial and add 3 cm to its length.
  3. Measure the width of all pens or vials side by side, sum their widths, and add 3 cm.
  4. Refer to the size chart image above to find the Dia-Cool that best fits your needs based on the width and length measurements.

Size Chart

Please refer to the size chart in the image above to see the available sizes (No.1 to No.8 Dia-Pencilcase) and their dimensions in both centimeters and inches.

How to Use Dia-Cool

Dia-Cool works through evaporation, keeping your medication at a safe temperature for 48 hours or more, depending on the ambient temperature. Follow these steps:

  • Submerge the Cool-Pack in water as instructed: 60 minutes for first-time use, 60 minutes after drying out, and 15-20 minutes for daily recharging.
  • Evenly distribute the Gel-Pearls inside the pack during submersion. Avoid overfilling to keep the pack pliable.
  • After soaking, allow the Cool-Pack to dry for 15-30 minutes. Ensure it feels dry to the touch before placing your medication inside.
  • Store your insulin or medication in the activated Cool-Pack and insert it into the outer bag, ensuring airflow for effective cooling.

Important Tips

- Do not leave the Cool-Pack submerged in water for longer than instructed. Over-soaking can cause the Gel-Pearls to absorb too much water, potentially leading to the pearls exploding and damaging the pack.
- Dia-Cool is not suitable for long-term storage; always store insulin in a refrigerator when not using Dia-Cool.
- Never place the Dia-Cool in a closed container; it needs ventilation to maintain the cooling effect.
- Follow the manufacturer's instructions for insulin storage and always keep insulin within the recommended temperature.

Our most popular size, 19.3 x 9.8 cm, fits a basal and a bolus pen side by side, or two vials. The Dia-Cool keeps insulin cool for 48 hours or more, depending on the ambient temperature, with nothing but cold water, which makes it a reliable companion for work days, weekends and holidays.

How to wear it

First use: soak the cooling pack in cold water for 1 hour maximum, never longer, or the gel pearls swell too much and burst.

To recharge it, soak it again for 5 to 10 minutes. Dry the outside of the pack and slide it back into the wallet with your insulin.

Never put the cooling pack in the fridge or the freezer.
