Nitrogen Cryosurgery Transfer Valve 

• Fills multiple units easily at a time.
• The valve is ideal for use with containers that have a 50 mm neck diameter.
• The device is mounted on top of the nitrogen container (i.e., it does not need to be removed after each use), features a simple on/off control, and operates like a tap.
• Includes a filter that helps clean the LN₂ before dispensing.
