Lab Techniques for biologists AHBio 1.1

• A risk is the likelihood of harm arising from the exposure to a hazard
• Control measures

  Using appropriate handling techniques, protective clothing and equipment and aseptic techniques
• Linear dilutions

  Dilutions differ by an equal interval eg. 0.1, 0.2, 0.3, 0.4
• Log (serial) dilutions

  Differ by constant proportio 10^-1, 10^-2 etc
• Buffers

  A solution where adding acids or alkalis have very small effects on the pH. This allows pH in a reaction mixture to be kept constant
