Transferring volumes using the three-way safety bulb
Once you have drawn up the desired volume of solution and
removed the drop hanging from the tip, record the initial volume
in the pipet.
To transfer the solution into the desired vessel, press the
empty valve (E) until the meniscus is at the mark corresponding
to the appropriate volume. 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 transferred is equal to the final pipet reading minus
the initial pipet reading.
