3
Dispense only to knowledgeable users.
The filler must determine that the user is knowledgable
about the general characteristics of the product and
the proper safety precautions for its use. Do not allow
customers to fill their own cylinders.
4
Dispose of cylinders properly.
To eliminate the risk of injury from the improper reuse
of cryogenic (vacuum jacketed) cylinders, before
disposal, destroy the cylinder's pressure retaining
capability.
We recommend:
•
Purging the cylinder's contents
• Drilling multiple holes through the cylinder and its
vacuum casing or otherwise puncture the tank.
Do it yourself! Don't assume it will be done by the scrap
dealer
Performance
The performance of a liquid cylinder can be shown in its
ability to hold cryogenic liquid and dispense it as a gas.
The normal evaporation rate (NER) is an indication of
how well the insulation system performs its ability to hold
cryogenic liquid. Figure 6 indicates how the insulation
performance affects the holding time for CO

and N

Figure 6
The pressure building system can be measured by how fast
it can increase pressure in the liquid cylinder (Figure 7) and
how well it maintains pressure while gas is being withdrawn
from the cylinder (Figures 8 & 9).
Performance data provided in the illustrations represents
typical values. Actual values may vary depending on ambient
conditions and/or the condition of the liquids
