To determine:
The micropipette used to measure 15 μl.
Introduction:
Micropipettes is a laboratory equipment that is used to measure or quantify the very small quantity of liquids. These pipettes are generally used in laboratories and the least quantity that these pipettes can measure is 0.1 μl. Micropipettes are found in different sizes and depending on their size, different tips are used for them.
Explanation of Solution
The micropipettes used in the laboratories are of three different sizes, P20, P200, and P1000. P20 micropipette is used to measure volume ranging between 0.5-20μl. P200 micropipette is used to measure volume ranging between 20-200 μl. P1000 micropipette is used to measure volume ranging between 100-1000 μl.
The micropipette used to measure 15 μl is P-20.
