Exercise 3: Pipettes

Pipettes are classified according to:

holds or contains a particular volume but does not dispense that exact volume

pipette that will dispense the volume indicated

has continuous etched ring or two small, close continuous rings located near the top of the pipet

pipette where the content drains by gravity.

the last drop of liquid should be expelled into the receiving vessel

measuring pipette or transfer pipette: Oswald Folin

measuring pipette or transfer pipette: volumetric

measuring pipette or transfer pipette: Mohr

measuring pipette or transfer pipette: serologic

measuring pipette or transfer pipette: pasteur

measuring pipette or transfer pipette: automatic micropipettes and macropipettes

measuring pipette or transfer pipette: Bacteriologic

measuring pipette or transfer pipette: Ball, Kolmer or Kahn

measuring pipette or transfer pipette: micropipette

can dispense different volumes

graduated pipette where graduations end above the tip

measuring pipette that has graduated marks down to the tip

the drainage characteristic of Mohr pipette is

the drainage characteristic of serological pipette is:

which has a larger orifice, serologic or mohr?

It transfers a known volume of liquid without further subdivisions.

calibrated to deliver accurately a fixed volume of a dilute aqueous solution.

have bulb closer to the delivery tip
