Transferring solution via standard bulb

Once you have drawn up the desired volume of solution and removed the drop hanging from the tip, record the initial volume of solution in the pipet.

To transfer the solution into the desired vessel, control the flow of liquid by slowly rolling your thumb or finger off the mouth of the pipet. Add solution until the appropriate volume has been transferred. Touch the tip of the pipet to the wall of the receiving vessel to remove any liquid from the outside of the tip. Record the final volume in the pipet. The volume of liquid transferred is equal to the final volume reading minus the initial volume reading.
