Understanding Micropipettors: Key Concepts and Procedures

This chapter focuses on the importance of micropipettors in laboratory settings, detailing their measurement capabilities in microliters and milliliters. Students will learn the significance of balancing centrifuge tubes and how to measure liquid volumes using the P-20, P-200, and P-1000 micropipettors. Furthermore, the chapter outlines the proper steps for drawing and dispensing liquids using these devices. Engaging visuals and practice exercises will enhance comprehension and retention of these critical laboratory skills.
