1. A type of adjustable micropipette that deliver a measured volume of liquid; depending on size, it could be between about 0.1 µl to 1000 µl (1 ml). These pipettes require disposable tips that come in contact with the fluid.
    Air displacement micropipette
  2. These are similar to air displacement pipettes, but are less commonly used and are used to avoid contamination and for volatile or viscous substances at small volumes, such as DNA. The major difference is that the disposable tip is a microsyringe (plastic), composed of a plunger which directly displaces the liquid.
    Positive Displacement Pipette
  3. allow the user to measure a volume of solution extremely precisely (precision of four significant figures). These pipettes have a large bulb with a long narrow portion above with a single graduation mark as it is calibrated for a single volume
    Volumetric Pipette
  4. Volumetric Pipette aka
    bulb pipette
  5. are a type of macropipette consisting of a long tube with a series of graduations, (as on a graduated cylinder or burette,) to indicate different calibrated volumes.
    Graduated Pipettes
  6. characterized by its purpose as blow-out pipette
    serological pipettes
  7. contains the graduation mark and color paired ring. The graduation marks reach to the end of the tip (down to the tip). The color paired ring only locates in. It can be blowed out by the gravitational force. Rubber bulbs are commonly used to blow the remained solution.  The calibration of TD (to deliver)  is contained in most of it
    Serological pipette
  8. characterized by its purpose as drain-out pipette.
    Mohr pipette
  9. It is the measuring pipet with straight tubes and graduation mark of 0.10-mL volume.  does not contain both the graduation mark until the end of the tip and the color paired ring located at the top of the pipette.
    Mohr pipette
  10. are plastic or glass pipettes used to transfer small amounts of liquids, but are not graduated or calibrated for any particular volume. The bulb is separate from the pipette body
    Pasteur Pipette
  11. Pasteur pipettes are also called
    • teat pipettes
    • droppers
    • eye droppers
    • chemical droppers
  12. are similar to Pasteur pipettes but are made from a single piece of plastic and their bulb can serve as the liquid-holding chamber.
    Transfer pipettes
  13. Transfer pipettes aka
    beral pipette
  14. It transfers a known volume of liquid without further subdivisions
    calibrated pipette/transfer pipette
  15. A calibration mark is etched around the upper suction tube.
    calibrated pipette/transfer pipette
  16. These are measuring pipette and can dispense different volumes as these have many graduations.
    graduation/measuring pipettes
  17. It has uniform graduations along its length.

  18. Cleaning of pipette (7)
    • Rinse with a detergent solution.
    • Rinse well with distilled water.
    • Rinse in 95% ethanol.
    • Allow to dry.
    • Soak the parts in 3% hydrogen peroxide for 10 minutes.
    • Thoroughly rinse with distilled water.
    • Air dry as above.
  19. Cleaning of pipette (4)
    • Place a small volume of the solution to be pipetted into a beaker.
    • Draw the solution into the pipette using a propiette or pipette pump, and then tilt and turn the pipette until all of the inner surfaces have been wetted by the solution.
    • Discard this washing solution as waste.
    • Repeat the previous steps again until beading is not observed on the inner walls of the pipette.
  20. Graduated/Measuring Pipettes
    • (SMB -smmbb)
    • serological
    • mohr
    • micropipette
    • bacteriologic, kahn, kolmer
  21. Calibrated/Transfer Pipettes
    • (PAVO -sounds like pabo)
    • Pasteur
    • Automatic macropipette/micropipette
    • Volumetric
    • Oswaldt-Folin
  22. are hand-held devices that combine the functions of volumetric (bulb) pipettes, graduated pipettes, and burettes. No disposable tips or pipetting aids are needed with the pipetting syringe.
    Pipetting syringes
  23. A graduated pipette commonly used in medical technology with serologic pipettes for volumetric analysis.
    Van Slyke Pipette
  24. Van Slyke Pipette was invented by
    Donald Dexter Van Slyke
  25. A special pipette used in measuring viscous fluid such as whole blood.
    Ostwald–Folin Pipette
  26. Invented by ....... , a Baltic German Chemist and later refined by ....,  an American chemist.
    Friedrich Wilhelm Ostwald,  Otto Folin
  27. These are used to physically interact with microscopic samples, such as in the procedures of microinjection and patch clamping.
    Glass Micropipette
  28. pipette that has a bulb closer to the delivery tip unlike volumetric pipett which has at center
