Ice pack

1. What are gel ice packs used for?
Gel ice packs are used to keep temperature-sensitive products cold during transportation. They are widely used for shipping recombinant proteins, antibodies, enzymes, reagents, biological samples, diagnostic kits, pharmaceuticals, vaccines, and other laboratory materials that require refrigerated conditions.
ProSpec gel ice packs provide a reliable cooling source when used together with insulated shipping boxes, helping maintain the cold chain throughout transit.

2. What are the best gel ice packs for shipping laboratory samples?
The best gel ice packs provide long-lasting cooling, are reusable, leak-resistant, and maintain a stable temperature throughout transportation.
For over 20 years, ProSpec has used its own gel ice packs to ship laboratory products worldwide. Designed specifically for research and biotechnology applications, they help protect valuable temperature-sensitive products during domestic and international shipping.

3. How do I keep biological samples cold during shipping?
To maintain sample integrity, biological materials should be shipped inside a high-performance insulated shipping box together with properly frozen gel ice packs.
For maximum thermal protection, ProSpec recommends combining its reusable gel ice packs with insulated shipping boxes constructed using Vacuum Insulated Panel (VIP) technology, which significantly reduces heat transfer and extends cooling performance.

4. How long do gel ice packs stay cold?
Cooling duration depends on several factors, including:
• Number of gel ice packs
• Type of insulated packaging
• Ambient temperature
• Shipment weight
• Transit time
Using ProSpec VIP insulated packaging together with ProSpec gel ice packs can significantly extend cooling duration compared to conventional insulated packaging.

5. Are ProSpec gel ice packs reusable?
Yes.
ProSpec gel ice packs are designed for repeated use. After delivery, simply refreeze them before the next shipment.
Reusable cooling packs reduce packaging costs, minimize waste, and provide an environmentally friendly solution for cold chain shipping.

6. What are the advantages of gel ice packs compared to regular ice?
Gel ice packs offer several important advantages over conventional ice:
• Leak-resistant
• Less risk of water damage
• Reusable
• Easy to freeze and store
• Longer-lasting cooling
• More uniform temperature distribution
• Antibacterial material
• Cleaner handling during shipping
Unlike pre-filled packs, ProSpec gel ice packs are supplied as a powder. Simply add water, seal the pack, freeze it, and it is ready for use.

7. What products should be shipped with gel ice packs?
Gel ice packs are recommended for shipping:
• Recombinant proteins
• Cytokines
• Growth factors
• Antibodies
• Enzymes
• ELISA kits
• Cell culture reagents
• Diagnostic kits
• Clinical samples
• Biological specimens
• Pharmaceuticals
• Temperature-sensitive laboratory reagents

8. How many gel ice packs do I need for shipping?
The required number depends on:
• Package dimensions
• Shipping duration
• Outside temperature
• Product weight
• Required storage temperature
As a general guideline, approximately 30% to 40% of the insulated box volume should be occupied by gel ice packs. ProSpec can help determine the optimal configuration for your application.

9. Are gel ice packs suitable for international shipping?
Yes.
ProSpec gel ice packs are designed for both domestic and international shipments. When combined with ProSpec VIP insulated shipping boxes, they help maintain cold chain integrity during long transportation routes, customs clearance, and unexpected shipping delays.
