    en.wikipedia.org/wiki/Eye_dropper

    An eye dropper, also called Pasteur pipette or simply dropper, is a device used to transfer small quantities of liquids. [1] They are used in the laboratory and also to dispense small amounts of liquid medicines. A very common use was to dispense eye drops into the eye. The commonly recognized form is a glass tube tapered to a narrow point (a ...

  4. Forward pipetting - Wikipedia

    en.wikipedia.org/wiki/Forward_pipetting

    Forward pipetting is a technique to dispense a measured quantity of liquid by means of air displacement pipette. The technique is mainly recommended for aqueous solutions, such as buffers, or diluted acids or alkalis. In case of solutions with a high viscosity or a tendency to foam, reverse pipetting is more suitable.

  5. Reverse pipetting - Wikipedia

    en.wikipedia.org/wiki/Reverse_pipetting

    Reverse pipetting is a technique to dispense a measured quantity of liquid by means of air displacement pipette. The technique is mainly recommended for solutions with a high viscosity or a tendency to foam: [1] as it reduces the risk of splashing, foam or bubble formation.

    30341-2. The erythrocyte sedimentation rate ( ESR or sed rate) is the rate at which red blood cells in anticoagulated whole blood descend in a standardized tube over a period of one hour. It is a common hematology test, and is a non-specific measure of inflammation . To perform the test, anticoagulated blood is traditionally placed in an ...

  11. Mohr pipette - Wikipedia

    en.wikipedia.org/wiki/Mohr_pipette

    A Mohr pipette, also known as a graduated pipette, is a type of pipette used to measure the volume of the liquid dispensed, although not as accurately as a volumetric pipette. These use a series of marked lines (as on a graduated cylinder) to indicate the different volumes.
