Understanding Pipette Accuracy and Precision
Ever been baking and accidentally added twice the amount of salt? Yikes! That’s a precision problem. In the lab, especially when dealing with sensitive samples or quantitative analyses, the accuracy and precision of your aspirating pipette are paramount. Accuracy means how close your measured volume is to the true volume, while precision means how repeatable your measurements are. Both are vital for reliable results.
Think about it this way: imagine trying to hit the bullseye on a dartboard. Accuracy is about getting the dart as close to the bullseye as possible, while precision is about consistently hitting the same spot, even if it’s not the bullseye. You want both – a dart that consistently lands right on the bullseye!
Choosing a pipette with certified accuracy and precision can save you headaches and wasted reagents down the line. Look for models that come with calibration certificates and specify the allowable error range. Regular calibration checks are also a must – think of it as giving your pipette a yearly check-up to ensure it’s still performing at its best.
