Catalog Number
Lecture Bottle, Carbon Dioxide
Product Description

The standard lecture bottle is 2" in diameter and 15" long. A lecture bottle will fill approximately five 11" balloons with gas. Carbon dioxide lecture bottle contains 0.5 lb (125 liters).

These lecture bottles are not refillable. Please consider our refillable gas cylinders. They provide more gas, eliminate disposal problems, and save you money.

Carbon Dioxide Gas
HAZARD ALERT: In solid form (solidified carbon dioxide - commonly known as dry ice) is very damaging to skin and eyes.
Storage: A cabinet dedicated to bottled gas storage.
Disposal: Completely empty lecture bottle in an operating fume hood then follow #26a.
Shelf Life: Indefinite
Soluble: Slightly soluble in water, hydrocarbons, and most organic solvents.
Color: Colorless
Odor: None
CAS No. 124-38-9 
Special Note: Carbon dioxide lecture bottle is color-coded solid brown.
Carbon Dioxide Gas Preparation: CO2 gas can be produced from dry ice. One to two pounds of dry ice should provide sufficient gas for 40-50 students. You will have to set up a generator apparatus that will enable you to heat the dry ice by placing chunks in a water bath. The evolution of gas is not sufficient unless warmed by water. Your delivery tube (from the generator) should be rather long to allow the gas to reach room temperature. A drying tube will also have to be part of the apparatus to remove moisture.
Some teachers will set up a CO2 generator using a flask (about 250 mL size) into which is placed a long-stem funnel and delivery tube. Using about 25 grams of calcium carbonate (Flinn Catalog Nos. C0347, C0012, C0013, and C0014) and 6 Molar hydrochloric acid (Flinn Catalog No. H0033) will produce approximately 6 liters of CO2 at room temperature and atmospheric pressure. A drying tube should be a part of the generation apparatus.
