How Much Dry Ice Packs Do You Need for Medicine?
Mulailah dengan 5lb (2.3 kg) dari paket es kering per 24 jam untuk pengirim terisolasi kotak sepatu. Sesuaikan dengan ± 2lb tergantung pada panas luar atau ketebalan kotak. Jaga Total Di Bawah 5.5lb (2.5 kg) Jika Anda terbang - aturan FAA masih menutupnya di level itu.
Paket Es Kering Sublimat lebih cepat di ruang kosong. Fill gaps with bubble wrap or foam inserts to stretch cooling time. For 48‑hour transport of frozen biologics, a 10 lb load in a 20‑qt cooler keeps contents below –20 °C reliably.
Dry Ice Pack Weight vs. Ukuran Pengiriman
| Volume Kotak | Paket Es Kering (pon /kg) | Hours Below –10 °C | Apa artinya bagimu |
|---|---|---|---|
| 5 L | 3 / 1.4 | ~18 h | Day‑surgery specimen runs |
| 10 L | 5 /2.3 | ~ 24h | Overnight pharmacy delivery |
| 20 L | 10 /4.5 | ~ 48h | Two‑day biologic shipping |
Tips Praktis
-
Pre‑freeze packs at –80 °C for maximum hold time.
-
Layer PCM bricks (2–8 ° C.) above vials that must not freeze.
-
Ventilasi pengirimnya; CO₂ gas needs an escape path.
Kasus nyata: A biotech firm shipped monoclonal antibodies at –75 °C for 36 h using 8 lb of dry ice packs in a 12 L VIP cooler—arrival temperature was –72 °C with zero vial breakage.
Will Dry Ice Packs Damage Temperature‑Sensitive Medicine?
Yes—if the medicine only needs 2–8 °C, direct contact with –78 °C packs can freeze and ruin it. Use a buffer layer: phase‑change gel packs or a 1‑inch foam spacer. Obat-obatan berlabel “tetap beku” (–20 °C or below) are dry‑ice friendly; most vaccines and insulin are not.
Medicine Storage Range Reference
| Jenis Obat | Safe Range | Dry Ice Compatible? | Membawa pergi |
|---|---|---|---|
| Insulin | 2–8 ° C. | ❌ | Use PCM or refrigerated carriers |
| vaksin mRNA | –90°C hingga –60°C | ✅ | Diperlukan es kering |
| Monoclonal antibody | –25 °C to –15 °C | ✅ | Requires buffer layer |
| Reconstituted antibiotics | 2–8 ° C. | ❌ | Gunakan paket gel, bukan es kering |
Tip yang Berfokus pada Pengguna
-
For refrigerated meds: Place them in a small cooler with +4 °C gel packs, then nest that cooler inside the dry‑ice shipper.
-
For frozen meds: Add a cardboard shelf between packs and vials to prevent glass cracking.
-

Lapisi bagian bawah of the shipper with a corrugated board.
-
Add one layer of dry ice packs, then a buffer sheet.
