A fixed volume micropipette with a two-step plunger is primarily designed for accurate and precise dispensing of a specific, predetermined volume of liquid. The two-step plunger mechanism enhances the functionality and accuracy in several ways:   Here's a breakdown of its uses and the benefits of the two-step plunger: Primary Uses: Routine and Repetitive Pipetting: Ideal for applications where the same volume of liquid needs to be dispensed repeatedly, such as in diagnostic kits, serial dilutions, or preparing multiple samples with the same reagent concentration.   High Accuracy and Precision: Fixed volume pipettes are generally more accurate and precise than adjustable volume pipettes because they are calibrated for a single volume, minimizing potential errors from volume adjustments.   Quality Control: Used in quality control processes where consistent and exact volumes are critical for reliable results. Educational Purposes: Excellent for teaching basic pipetting techniques an
