VS 8-2: Lower Profile for Freight Efficiency

The Phasetwo VS 8-2 was engineered with direct input from cell and gene therapy customers to meet the real-world challenges of global distribution. Its lower-profile design is purpose-built for freight efficiency—reducing shipping costs without compromising cryogenic performance.

With up to 15 days of static hold time and 13 days horizontal hold time, the VS 8-2 ensures product integrity even under demanding conditions. The tank size and payload configuration are optimized for what’s most commonly shipped in cell and gene therapy workflows—cassettes, vials, and straws—making it the ideal solution for clinical trials and commercial-scale operations.

For complete peace of mind, the VS 8-2 offers optional real-time monitoring through the integrated Sendum In-Transit Monitoring System, giving you full visibility into temperature and location throughout the journey. Combined with rapid LN₂ charging and a stackable, lockable case, the VS 8-2 delivers unmatched reliability and efficiency.

Key Highlights:

LN₂ Capacity: 8 L
Dimensions: 16 in × 20.2 in
Weight Full: 43.2 lbs
Hold Time: 15 days static, 13 days horizontal
Payload Options: Cassette Rack (250ml, 50ml) ; 2in Vial Boxes (2)
