Hi Travis,<br>
<br>
We have a scale for our CO2 cylinder and track the weight with CPD
use. With our system, we get about 5 CPD runs before the cylinder
has to be changed. These 5 runs will not empty the cylinder
completely, so we attach the nearly empty cylinder to a Sno-Gun to
use up the rest of the CO2.<br>
<br>
Best Regards,<br>
Brent

<div>Hello everyone,</div>
<div><br>
</div>
<div>Curious how other labs are using Co2 cylinders on their
CPD systems. How much CO2 do you use before replacing the
cylinder? How do you monitor CO2 usage?</div>

<div>Thanks!</div>
