2. Engr 1182.03 Chemical Safety Anything that you are not familiar with should be handled carefully Every time a chemical is sold or shipped it must be documented by a "Material Safety Data Sheet" or MSDS –http://www.ilpi.com/msds/index.html –Another useful reference is Sax's Dangerous Properties of Industrial Materials by Richard J. Lewis In any process where chemicals are to be used, safety is the highest priority –Gloves, Glasses, Coat, and Boots as appropriate Rev: 20XXMMDD, InitialsPresentation Short Title2

5. Engr 1182.03 Degassing Procedure Pay close attention to valve positions for cycling vacuum on and off. Do not open the vacuum line directly to the atmosphere. The following four slides demonstrate the possible positions for the stopcock and the two that should not be used. Rev: 20XXMMDD, InitialsPresentation Short Title5

6. Engr 1182.03 Rev: 20XXMMDD, InitialsPresentation Short Title6 Desiccator Vacuum Source Atmosphere This configuration pulls air from the desiccator to the vacuum pump, creating a vacuum in the desiccator (for removing bubbles in PDMS).

7. Engr 1182.03 Rev: 20XXMMDD, InitialsPresentation Short Title7 P. 7 Desiccator Vacuum Source Atmosphere This configuration releases the vacuum from the desiccator and equalizes the pressure in the desiccator with that of the atmosphere (for de-foaming or overflow prevention).

8. Engr 1182.03 Rev: 20XXMMDD, InitialsPresentation Short Title8 P. 8 Desiccator Vacuum Source Atmosphere This configuration opens all three airways on the stopcock and releases the vacuum from the desiccator and the entire vacuum system. THE STOPCOCK SHOULD NEVER BE SET THIS WAY!!!!

9. Engr 1182.03 Rev: 20XXMMDD, InitialsPresentation Short Title9 Desiccator Vacuum Source Atmosphere This configuration releases the vacuum from the entire vacuum system, but maintains the current pressure in the desiccator. THE STOPCOCK SHOULD NEVER BE SET THIS WAY!!!!

10. Engr 1182.03 Notes on Procedure Bubbles in syringes not too important unless excessive. Make sure you pour the mixture into the bottoms of the petri dishes. The bottoms have the smaller diameter. Put group name on petri dishes and stack on table specified in lab. Rev: 20XXMMDD, InitialsPresentation Short Title10
