Mohr pipettes and serological pipettes are the two most important classes of graduated pipettes.

approach: above-rotated forearm and wrist. Rotation with the forearm in a very supinated place (palm up) and/or wrist flexion improves the fluid pressure inside the carpal tunnel.

If you're managing several samples in a very limited time, you may perhaps make use of a multichannel pipette. even now, common laboratories use micropipettes, so acquiring the tips well suited for the two types in bulk is much more affordable.
