The best way to secure a pure culture from a mixed one would like to pick out a single cell of the desired type. This can be done by the use of micromanipulator in contamination with a microscope. Micromanipulator has a micropipette with a very fine capillary point. The micropipette can be moved as desire. A single cell can be picked using micropipette and transferred to a suitable nutrient medium.
Disadvantages-
This technique requires a skilled operator, is cumbersome to operate and involves greater chances of contamination during operation.

In the life sciences laboratory environment, there are few pieces of equipment which see more use than a multichannel pipette and along with it, pipette tips.
