Shaking the sample before transferring it into a sterile McCartney bottle helps to ensure homogeneity of the sample, allowing for a representative portion to be transferred. This helps to minimize sampling errors and ensures accurate analysis of the sample. Additionally, shaking the sample helps to resuspend any settled particles or components, leading to a more uniform distribution in the McCartney bottle.

Transferring culture from an open broth tube to a sterile broth tube introduces microorganisms from the original culture into the sterile environment. If the transfer is done aseptically, the sterile broth will facilitate the growth of the introduced microorganisms, leading to an increase in their population. However, any contamination from the open tube could also introduce unwanted microbes, potentially affecting the purity and results of the culture. Proper aseptic techniques are crucial to minimize contamination during this process.
