providing the desired volume of mercury Together with the pipette into a pre-weighed thoroughly clean glass beaker checks calibration. The beaker is weighed all over again. the burden of the mercury in mg must be in accordance with the amount in ml.
The disposable piston in the capillary piston (CP) tip is in direct contact with the sample. The CP know-how Therefore eliminates any air cushion In the pipette and makes sure the quantity accuracy isn't afflicted with the fluid's properties.
