# 2 - FASTER AND MORE ECONOMIC TESTING
Conventional destructive testing can
take as long as 4 minutes , including the
time spent shaking the sample to reach
pressure equilibrium and the time to
interpret results . Impeller methods are
slightly faster , as results are displayed
digitally . The LAB . CO completes the test
in less than one minute , including the
same shaking duration ; the reading itself
does not take more than a few seconds .
Bottlers can perform the same task in ⅓
or ¼ of the time , releasing the analyst to
perform other functions or increasing the
number of tests performed during that
same time .

Closure and bottle manufacturers also |
|||
benefit from nondestructive methods |
|||
by performing shelf-life testing with the |
|||
same bottle over long periods of time , |
|||
with a more precise evaluation of the |
|||
loss of gases in lightweight designs . |
|||
Destructive test methods require |
|||
production of 7-9 samples per cavity to |
|||
complete the evaluation , as opposed to |
|||
a single sample per cavity , with higher
accuracy as no variability is added by
multiple samples .
