HORIZON SCIENTIFIC ABSPS80 LN 2 Phase Separator
The ABSPS80 LN 2 Phase Separator from Horizon Scientific is designed to reduce liquid nitrogen loss during transfer, with an inner tube lining aimed at minimizing cooldown losses. This component helps maintain LN2 at a stable temperature during transfer, supporting safer handling and improved efficiency in nitrogen transfer operations. The device integrates with standard LN2 hoses and is particularly suitable for laboratory setups where minimizing helium or nitrogen waste matters. Its robust construction supports repeated use in cryogenic environments, contributing to more economical LN2 management over time.
Transfer Hose Nitrogen Tank Kit
The Transfer Hose Nitrogen Tank Kit from Joes Racing offers a compact package tailored for nitrogen handling. While the listing emphasizes kit packaging dimensions and weight, the kit typically supports straightforward LN2 transfer with a dependable hose assembly. Users should verify compatibility with their existing regulators and cryogenic fittings. It is well-suited for small-scale LN2 transfers and educational or research applications where portability and simplicity are prioritized. The product’s lightweight profile can aid in quick setup and teardown for routine LN2 tasks.
Western Enterprises WMH-2-14 Cryogenic Hoses
Western Enterprises WMH-2-14 Cryogenic Hoses are designed for nitrogen and argon transfer, offering exceptional flexibility with resistance to kinking. Cleaned for oxygen service, these hoses come with machined CGA stainless steel end connections to ensure secure, leak-tight joins. The combination of flexibility and durable end fittings makes these hoses suitable for laboratory transfer lines, nitrogen purging, and inertization tasks where reliable, uninterrupted flow is essential. The 48″ length provides enough reach for many standard benchtop transfer applications while remaining manageable for storage.
OTC Tools CEA-041 25′ Coiled Hose
The OTC Tools CEA-041 25′ Long Nitrogen Coiled Hose provides extended reach for LN2 transfer with the convenience of a recoil design that retracts after use. This accessory is positioned as part of a broader diagnostic or servicing environment, including compatibility with nitrogen purge and leak-check tasks. The 25-foot length supports larger benches or equipment setups where shorter hoses would be impractical. Its coil design helps reduce hose tangling and storage space requirements while enabling flexible operation in lab areas.
RX WELD Nitrogen Regulator with 5Ft Hose
RX WELD’s Nitrogen Regulator includes a 5 ft refrigeration hose and a 0-600 PSI gauge, with a protective rubber gauge boot. The regulator supports gas supply for LN2 transfer, purging, and inertization tasks, offering a practical balance between precise pressure control and hose length. With a CGA580 inlet and a 1/4-inch male flare outlet, it facilitates straightforward integration into standard nitrogen transfer systems. The unit is marketed toward professionals performing HVAC purging, brazing, and related cryogenic operations where reliable pressure management is essential.
Buying Guide
Key considerations when selecting a liquid nitrogen transfer hose system include compatibility, temperature resilience, and safety features. It is important to match hose connections (CGA, 1/4″ flare, etc.) to existing regulators and adapters to prevent leaks. Length and flexibility influence reach and maneuverability, while coatings and inner linings affect cooldown losses and LN2 conservation. Consider the operating environment: some hoses are cleaned for oxygen service and are better suited for cryogenic labs, while others emphasize portability for field use. Assess the need for phase separation or additional components (regulators, manifolds, coiled designs) to support specific workflows such as inertization, leak testing, or rapid transfer.
- Connection standards: Verify CGA580 or 1/4″ flare fittings and compatibility with regulators.
- Length versus maneuverability: Longer hoses extend reach but increase weight and potential cooldown losses.
- Material and construction: Inner linings and phase separators reduce LN2 loss and cooldown times; stainless steel ends improve durability.
- Safety and gauges: Clear, legible gauges and protective boots help monitor pressure and prevent over-pressurization.
- Use case alignment: Choose hoses and regulators tailored for purging, inertization, or general transfer to avoid over-specifying equipment.
