Specs & features.
The device attaches to the neck flange of standard storage dewars (such as 25L, 35L, or 50L models). As the extremely cold liquid boils off, it creates head pressure in the gaseous headspace of the container. When the operator opens the dispenser lever or valve, this internal pressure pushes the liquid nitrogen up a hollow dip tube and out through a dispensing spout or cryogenic hose
No specifications have been listed.
- Controlled Flow Control: Features faucet-style, on/off controls or trigger mechanisms that allow smooth extraction without splashing.
- No-Removal Refilling: Allows dewars to be refilled with fresh LN₂ without having to remove the entire withdrawal assembly.
- High Flow Rates: Capable of dispensing LN₂ safely at rates of 4 to 8 liters per minute at low working pressures (typically 4 to 10 psi).
