  2. Volumetric flask - Wikipedia

    en.wikipedia.org/wiki/Volumetric_flask

    A 100 ml volumetric flask with stopper Volumetric flasks of various sizes. A volumetric flask (measuring flask or graduated flask) is a piece of laboratory apparatus, a type of laboratory flask, calibrated to contain a precise volume at a certain temperature. Volumetric flasks are used for precise dilutions and preparation of standard solutions ...

  3. Laboratory flask - Wikipedia

    en.wikipedia.org/wiki/Laboratory_flask

    Volumetric flask is used for preparing liquids with volumes of high precision. It is a flask with an approximately pear-shaped body and a long neck with a circumferential fill line. Dewar flask is a double-walled flask having a near-vacuum between the two walls. These come in a variety of shapes and sizes; some are large and tube-like, others ...

  4. Laboratory glassware - Wikipedia

    en.wikipedia.org/wiki/Laboratory_glassware

    Three beakers, an Erlenmeyer flask, a graduated cylinder and a volumetric flask. Laboratory glassware is a variety of equipment used in scientific work, traditionally made of glass. Glass may be blown, bent, cut, molded, or formed into many sizes and shapes. It is commonly used in chemistry, biology, and analytical laboratories.

  5. Titration - Wikipedia

    en.wikipedia.org/wiki/Titration

    A burette and Erlenmeyer flask (conical flask) being used for an acid–base titration. Titration (also known as titrimetry [1] and volumetric analysis) is a common laboratory method of quantitative chemical analysis to determine the concentration of an identified analyte (a substance to be analyzed).

  7. Pipette - Wikipedia

    en.wikipedia.org/wiki/Pipette

    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 (like a volumetric flask). Typical volumes are 20, 50, and 100 mL. Volumetric pipettes are commonly used to make laboratory solutions from a base stock as well as prepare solutions for titration.

  8. Standard solution - Wikipedia

    en.wikipedia.org/wiki/Standard_solution

    For this reason, glassware with high degree of precision such as a volumetric flask, volumetric pipette, micropipettes, and automatic pipettes are used in the preparation steps. The solvent used must also be pure and readily able to dissolve the solute into a homogenous solution. [2]

  9. Graduated pipette - Wikipedia

    en.wikipedia.org/wiki/Graduated_pipette

    A small pipette allows for more precise measurement of fluids; a larger pipette can be used to measure volumes when the accuracy of the measurement is less critical. Accordingly, pipettes vary in volume, with most measuring between 0 and 25.0 millilitres (0.00 and 0.88 imp fl oz; 0.00 and 0.85 US fl oz).
