Flaming the test tube’s mouth is necessary so that the moisture that accumulated will evaporate. 4. After Gram staining, the Gram positive bacteria will appear blue while the Gram negative bacteria will appear red.Idenitfy the statements whether they are TRUE or FALSE 1. You should use P-20 micropipettes to transfer volumes for spread plating. 2. You should use P-200 micropipettes to transfer volumes for pour plating.TRUE or FALSE only! 1. The most important step in doing a slide mount technique is fixing the sample with heat or chemicals. 2. Diluted samples from the serial dilution procedure are used for pour plating and spread plating methods which can be done simultaneously. 3. In doing aseptic techniques, it is practiced to touch the tip of the inoculating loop to test its coolness for transfer of cultures. 4. One of the important points to consider when calibrating an ocular micrometer is that its lines must properly superimpose with that of a stage microruler.
