Lecture Bottle
Lecture bottles are small, compressed gas cylinders, typically 12-18 inches long and 2-3 inches in diameter. Although they are small and easily transported, they are still pressurized cylinders which must be considered a dangerous source of high energy. Lecture bottles also often contain high hazard or acutely toxic gases. Be sure to follow the requirements of the Compressed Gas Cylinder Policy (Appendix B of General Laboratory Safety Manual).
Lecture Bottle Storage
- Lecture bottles must be stored in an upright position.
- Segregate incompatible gases, such as flammable and oxidizing gases.
- Store poisonous gases in a fume hood or a ventilated gas cabinet.
- Regulators must be removed during storage.
- Lecture bottles must be properly labeled.
Lecture Bottle Use
- Inspect the lecture bottle and regulator prior to use.
- Only use regulators and tubing that are appropriate for the gas.
- Lecture bottles must be properly secured during use and lecture bottles containing hazardous gases (corrosive or poison) must be used in a fume hood or gas cabinet.
Lecture Bottle Purchase and Disposal
- Unlike other gas cylinders, lecture bottles are not refillable and are purchased outright by the laboratory.
- Lecture bottles are costly to dispose of. Avoid purchasing non-returnable lecture bottles, or from suppliers who do not accept returned lecture bottles with unused or empty contents.
- Contact the supplier to obtain specific guidelines for shipment of lecture bottles to be returned to them.
- Contact EHS to arrange for the removal of lecture bottles that cannot be returned to the supplier.
