How to Determine Calibration Frequency for Pipettes in the Lab

Since the silent and random failures of pipettes, the most important aspect of pipette quality control is to maintain a calibration frequency with sufficient reliability. Here are the step-by-step guidelines for you to use.

Multi Channel Pipettes

1.Gravimetry is a calibration technique in which the weight of a liquid is measured on an analytical balance. However, this method will hinder frequent calibration because the calculation is time-consuming and cumbersome, especially for multi-channel instruments. Gravimetry also requires a controllable environment to work properly, because it is affected by evaporation, static electricity, and vibration, especially when measuring small volumes.

2.Single dye photometric calibration measures the absorbance of the dye solution at a given wavelength to verify the liquid volume. This technique is less affected by the environment and evaporation, which makes the photometry a distinct advantage at lower volumes.

3.Ratiometric photometry is another calibration method. This patented technology relies on two dyes for more precise volume measurement, especially for low volume measurement.
