Product Description

The standard lecture bottle is 2" in diameter and 15" long. A lecture bottle will fill approximately five 11" balloons with gas. Helium lecture bottle contains 2 cu. ft. (56 liters).

These lecture bottles are not refillable. Please consider our refillable gas cylinders. They provide more gas, eliminate disposal problems, and save you money.
Helium Gas
 HAZARD ALERT: Please do not allow students to inhale helium. Government health agencies and industrial safety representatives have taken strong stands against the practice of breathing helium to demonstrate the change in pitch that occurs when breathing a lighter-than-air gas. Breathing helium removes oxygen from the bloodstream, so it's not the same and actually worse than just "holding your breath."
Storage: In an area dedicated to bottled gases.
Disposal: Completely empty lecture bottle, then follow #26a.
Shelf Life: Indefinite
Soluble: Slightly in water; insoluble in alcohol.
Color: None
Odor: None
CAS No. 7440-59-7
Technical Note: Helium gas lecture bottle is color-coded with the top half yellow and the bottom half black.

Due to a worldwide shortage of helium, the cost of helium gas cylinders has increased dramatically. Flinn Scientific has done and will continue to do everything we can to keep the costs affordable for our customers.
