clamp, as shown in Figure 3. Attach the vacuum hose which goes to the valve 

assembly to the other side of the Dewar U-Tube using the metal clamp.  

 

Figure 3 - Dewar Vacuum Hose Connections 

 

 

Connect the 1/8” line from the compressed nitrogen regulator to the 1/8” Dewar 

U-tube fitting as shown in Figure 4. Connect the other side of the 1/8” Dewar U-

Tube line to the bottom of the humidification chamber, described in the next 

section. Once the system has been assembled, leak checked, and is ready to 

run, the Dewar can be filled with liquid nitrogen or liquid argon. The user should 

be able to lift the insulating lid with all the Dewar connections intact.
