These aseptic techniques will allow for the best results and viewing of specimen. Another purpose is to learn the techniques of gram staining to differentiate the differences among gram negative and gram positive bacteria. Procedure for aseptic techniques : 1. Turn on incinerator and allow it to run for a couple minutes as it heats up. 2. To avoid contamination, avoid sudden movements and work slowly over the bench.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
