Generally labs are working for different types of tests. For these tests the technicians have to draw different types of liquids which they cannot handle through hands. For this they need to have specific tools known as pipette. Without these devices they cannot work in the lab. Even you can say that without them they can be handicapped for the work related tests and all in the laboratory.
