SERLNG today highlights its latest advances in eco-conscious cryogenic logistics with a lineup of dry shippers designed to deliver safe, spill-free transport while minimizing liquid nitrogen consumption and environmental impact. Combining advanced adsorbent technology, durable construction, and long hold times, the new product families address the growing need for sustainable cold-chain solutions in research, clinical, and biomanufacturing sectors.
Green design that reduces waste and carbon footprint
Traditional wet cryogenic containers can lead to high liquid nitrogen (LN₂) loss and the associated energy and supply impacts. SERLNG’s dry shippers instead use a high-performance adsorbent material that holds cryogen securely inside the container. This adsorption approach prevents spills if a unit is tipped and substantially lowers LN₂ boil-off during transit — reducing both operational cost and carbon footprint for organizations that rely on frequent cryogenic shipments.
Product highlights — right model for every need
SERLNG offers three core series engineered for different capacity and application demands:
SERLNG YDH Series Dry Shippers
The SERLNG YDH Series Dry Shippers are compact, highly portable units with a capacity range from 3 to 20 liters. Available in five model sizes, the YDH Series is ideal for laboratories and field teams that require frequent small-batch shipments with minimal LN₂ topping. Their small footprint and low weight make them a top choice for courier-based sample transfer and point-of-care logistics.
Capacity: 3–20 L (5 models available) · Typical use: diagnostic samples, biomaterials, small clinical shipments
YDS Series Dry Shipper
The YDS Series is designed for robust, everyday cryogenic transport. Engineered to maintain internal temperatures down to approximately -190°C until the adsorbent's liquid nitrogen is exhausted, YDS units are suited to transporting diverse materials — from frozen tissues to biological reagents — with guaranteed spill resistance even when handled roughly.
Key feature: Unique adsorbent material prevents liquid spills · Storage temp: approx. -190°C inside the shipping cavity
YDS-B Series Dry Shipper
For higher volume requirements, the YDS-B Series covers larger capacities from 20 to 100 liters with twelve available models. These units serve biobanks, larger clinical centers, and distribution hubs that need extended hold times, larger payloads, and reliable reuse cycles to support sustainable operations.
Why dry shippers support sustainable cold chains
Lower LN₂ consumption: Adsorbent technology reduces nitrogen boil-off versus conventional wet dewars.
Reusable and durable: Long service life promotes circular use and reduces single-use waste.
Spill-free safety: No liquid spill risk when tipped — safer for handlers and cleaner for the environment.
Compliance friendly: Suitable for air transport and aligns with green logistics policies.
Real-world impact: case example
Early adopters of SERLNG dry shippers report measurable benefits: reduced supply purchases of LN₂, simplified handling procedures, and fewer safety incidents related to liquid spills. In aggregate, organizations that switch to adsorption-based dry shipping often experience a meaningful reduction in logistics-related emissions and operating costs.
Commitment to continuous improvement
SERLNG continues to invest in material science and insulation engineering to extend hold times and improve reusability. Future roadmap items include optimizing adsorbent formulations for even lower boil-off, expanding service and refurbishment programs, and supporting customers with lifecycle analyses to quantify sustainability gains.
