We need to use realistic transfer option when you need to transfer any amount of liquid from the container as per requirement and is not a definite amount.
We need to use precise transfer mode when you want to transfer the exact amount up-to third decimal position.
We need to use significant transfer mode when we use pipets or measuring cylinders that hold a definite volume of liquid.
Precise transfer can be used for both solids and liquids.
Significant transfer can be used only for transfer of liquids from pipet or measuring cylinder. It can only transfer the maximum amount of liquid the glassware can hold.for example when using 10 mL pipet we exactly transfer 10.00 mL using significant transfer mode. We cannot transfer say 5.5 mL or 8 mL. We need to type in 10.00 mL for the transfer to happen.
The best mode of transfer is precise transfer. Using this mode, one can transfer decimal values of volume (in mL).
** Significant transfer (as far as the current stage of development) allows transfer of non-decimal values of volume (in mL).
*** Realistic transfer does not allow for a definite amount of volume transfer. When selected, the transfer bar is inactivated & only pour button is activated. Each click on the pour button will give out differing volumes (in mL). May be the developers intended to create real time lab-like situation.
Can we use directly 100ml Erlenmeyer Flask instead of using graduated cylinder and distill Water.. Does that have a significant impact on the final reading...or add on to percentage error?
An erlenmeyer flask cannot be used for measurement, because meniscus of the liquid may not be clearly visible. Moreover, volumetric flasks are not calibrated as they are mainly used as reaction vessels etc. </span>
**** It is better to avoid a graduated cylinder when accurate measurements are required. Better to use a pipet or a burette.
