Vacuum Insulated Transfer Siphon … for low-loss transfer of liquid helium

Bend protection and pressure valve The liquid helium is withdrawn from a vessel using a siphon, which is available in various configurations: • Angle siphon • Siphon with flexible hose • Siphon with rigid hose Cryotherm siphons are made from super-insulated hoses and provided a permanent vacuum. These features guarantee the lowest transfer losses at all times. • Highly flexible hoses for easy handling and versatile applications • Improved insulation using thin-walled tubes and spacers • Low heat transfer through optimised super-insulation • Easy handling • High functionality • Extendable filling...

Permanently installed siphon in STRATOS® vessel with patented anti-oscillation device: • Low evaporation rate • No helium loss during siphon installation • Ideal for room with low height • Low wear of siphon due to vessel integration Manual shut-off valve with LHe male coupling Manual shut-off valve DN9, O-ring sealed - Short transfer times - Flexible use with add-on adapter set - Standard for STRATOS® vessels - Combined with anti-oscillation device Withdrawal tube Protective closures Manual shut-off valve DN5/DN7, bellows sealed - Installed in the filling tube to save space - Low maintenance...
