How do you use a bulb-pipettes instead of graduated cylinders or volumetric flasks?

Answer 1

You just use a pipet bulb to draw the liquid into the pipet to fill it above the line. With your finger on the top, you let the liquid out slowly until the miniscus is right at the line. Then pipet then contains exactly the volume indicated. Then, let the liquid flow out of the pipet. You should touch the tip of the pipet to the side of the beaker or flask that you're dispensing into. You should not blow out the last bit of liquid in the tip.

Answer 2

You use a bulb pipette because it's far more accurate then a graduated cylinder or volumetric flask. You use it by simply squeezing the blue pipette bulb and once the liquid gets to the fill line you cover it with your finger and transfer it to where you want it.

Answer 3

Pipettes hold very small volumes, like only 10-30ml. Graduated cylinders are a little larger, they would hold like 500ml, and volumetric flasks are the largest, they could hold 1-2 liters.

Answer 4

pipets are easier for transporting liquids. You would NEVER use this as a source of measurment. Pipets are soley for taking a small amount of a material and putting it in an area for a reaction
