What is the difference between a dip tube and a siphon tube?

http://www.nuffieldfoundation.org/practical-physics/co2-cylinder-syphon-typeA CO2 gas cylinder should be fitted with a dip tube (this is also called a `syphon type' cylinder). This enables you to extract from the cylinder bottom so that you get CO2 in its liquid form, not the vapour.

What's the conversion rate of liquid to solid. Pounds of liquid to solid product?

Hi Doug, My name is Mike at Bel-Art/H-B Instrument & SP Scienceware. The rate is variable by user, but averages out to 5 pounds liquid to 1 pound solid. A 50-lb Liquid CO2 tank will produce about ten 1-lb bags of Dry Ice. I hope this answered your question, but if not, please email me at mgrzelak@belart.com…

How much Dry ice can this machine produce in an hour?

We never left it on for an hour straight. I know 15-20 seconds produces about half of a bag. We haven't been doing enough experiments or batches to know how long a cylinder of CO2 gas will last. Hope that helps.
