The disposable piston within the capillary piston (CP) tip is in immediate Speak to with the sample. The CP engineering So gets rid of any air cushion In the pipette and makes certain the quantity precision will not be influenced because of the fluid's Qualities. This also assists avoid contamination and protects the sample, the consumer, as well helpful resources as pipette.
You will need to in no way expose any volumetric glassware to resources of heat due to the fact such exposure will adversely affect the calibration. Hence, it's essential to in no way dry any volumetric glassware in a very drying oven.
The amount of liquid dispensed is calculated by subtracting the final volume from the original quantity existing from the pipette.
