Revolutionize Cold Storage: The Refport Portable Stirling Freezer—Where Science Meets Mobility

In the fast-paced world of biomedical research, vaccine distribution, and clinical trials, one challenge persists:

How do you maintain ultra-low temperatures for critical samples when mobility and sustainability are non-negotiable?

Enter the Portable Stirling Freezer — a game-changing innovation designed to redefine reliability, portability, and environmental responsibility in cold chain logistics.

Why the Portable Stirling Freezer is the Future of Mobile Cold Storage

Whether you're transporting mRNA vaccines to a remote clinic, preserving stem cells during fieldwork, or safeguarding reagents in a power outage, traditional freezers and dry ice simply can't match the precision, safety, or convenience of Stirling technology.

Here’s why labs, hospitals, and biotech firms worldwide are making the switch:

1.  Unmatched Portability, Uncompromised Performance

• Lightweight & Compact: Just 18 kg (40 lbs)—about the size of a large suitcase—this freezer is made for mobility.
  No forklifts, no dry ice trucks—just science on the go.

• Power Anywhere: Compatible with 100–240 V AC, 12 V DC car ports, or portable batteries.
  Perfect for off-grid research, disaster response, and mobile vaccination drives.

2. ❄️ Ultra-Low Temperatures, Unshakable Stability

• -86℃ Precision: Maintain sample stability for vaccines, CAR-T cells, and enzymes at -80℃ ±1℃—even in unstable environments.

• Rapid Cooling: Achieve target temperature from ambient in just 4 hours, outperforming conventional systems.

3.  Sustainability Without Sacrifice

• Zero Dry Ice, Zero Risk: Say goodbye to CO₂ emissions, frost burns, and regulatory headaches.

• Eco-Friendly Refrigerants: Utilizes helium or hydrogen gas—no Freon, no ozone damage.
  ✔️ EPA-approved
  ✔️ Net Zero aligned

• Energy Saver: Uses just 2.8 kWh/day at -80℃—up to 70% less energy than traditional ULT freezers.

4.  Built for the Demands of Modern Science

• Optimized Storage:
  The Refport Stirling DW-8625 (25L) holds:

• 1,800 × 2ml tubes

• 18 cryoboxes
  Ideal for high-value, small-batch samples.

• Military-Grade Durability:

• Rugged ABS corrosion-resistant shell

• Vacuum insulation panels (VIP)
  Built for the lab, the field, and everything in between.

Who Needs a Portable Stirling Freezer?

• Biotech & Pharma: Secure mRNA, gene therapies, and trial materials.

• Hospitals & Blood Banks: Store vaccines, plasma, and organs during outages.

• Field Researchers: Replace dry ice in extreme environments—deserts, forests, or the Arctic.

• Diagnostic Labs: Preserve COVID-19 tests, RNA samples, and forensic evidence—zero downtime.
