MLT Introduction to Clinical Chemistry Practice Test

Measuring very small volumes with high precision requires an instrument designed for microliter-scale transfers. A micropipette is built exactly for that role. It lets you set a specific volume, draw liquid into a disposable tip, and then dispense that exact amount into a receiving vessel, minimizing variability between trials. The volume is adjustable and read from a display, with common ranges from a few microliters up to about 1000 µL, making it the standard tool for precise reagent addition in clinical chemistry and molecular biology. This precision depends on proper technique and calibration, and disposable tips help prevent cross-contamination.

Quality control is a process, not an instrument; the metric system is a measurement system, not a tool for transferring liquids; a self-draining pipette is a type of pipette but is not optimized for the tiny, precise amounts that micropipettes are designed to handle.
