The 2 lessons are Course A and Course B. Course A pipettes are manufactured to precise tolerances, or "error limits". Class B are allowed twice the error limitations of Class A. The category specification or serial variety of Class B are usually not marked.

Pipette Suggestion: Produced from polypropylene or molded plastic, this crucial piece will come into direct connection with the liquid.
