How is impact of pipetting technique-Artel lab report 2?
Each experiment consisted of two runs of ten data points each, using an adjustable 20 μL Eppendorf manual action air displacement pipette† set at 5 μL and Eppendorf disposable pipette tips, on the Artel PCS® Pipette Calibration System. Each experiment was performed as a comparison of one pipetting technique versus another.
How many times do you depress a pipette?
Let’s review the results of a study conducted at Artel to determine these differences and assess their impact upon pipetting accuracy. The reference pipetting method used in each of these experiments was as follows: The pipette mechanism was “warmed up” by gently depressing and releasing the plunger 15 to 20 times.
How is the impact of a pipette magnified?
†In an air displacement pipette, many sources of pipetting error are magnified by the ratio of “dead air” above the liquid level to the liquid volume in the tip. 2-6 In conducting these experiments, a 20 μL pipette was used to deliver 5 μL, so the amount of dead air was increased, compared to pipetting 20 μL with the same pipette. 1.
How does temperature affect the trueness of pipetting?
Experiment showing the effect of sample temperature on the trueness of pipetting results, using a 20 µL adjustable air displacement pipette set at 5 µL. Ambient temperature 25.0 °C. In addition to trueness problems seen with samples that were not at room temperature, there was some difficulty in obtaining good precision.
