Tips dispensing accuracy
Three types of pipettes (p1000, p200, p20) were tested at their lowest and highest volumes.
Tips of each of these pipettes were reconditioned through our process.
For each volume, 10 new tips and 10 reconditioned tips were used to dispense deionized water, following a standardised pipetting technique. Each dispensed volume was weighed, and the balance was tared between measurements. This process was repeated for each tip type, and the weights were recorded. The data was then analysed to calculate the standard deviation, coefficient of variation, and accuracy, comparing new and reconditioned tips.
This experiment allowed us to compare volume dispensing accuracy between new and reconditioned tips.
Results
All pipetted volumes were within the acceptable range given by the pipetman’s manufacturer for the coefficient of variation and for the accuracy percentage, indicating that reconditioned tips do deliver a precise volume.
Conclusion
Our reconditioning process allows the use of reconditioned pipette tips in experiments requiring precise volume dispensing.
