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.
