2. Graduated cylinder - Wikipedia

   en.wikipedia.org/wiki/Graduated_cylinder

   For accuracy the volume on graduated cylinders is depicted on scales with 3 significant digits: 100mL cylinders have 1ml grading divisions while 10mL cylinders have 0.1 mL grading divisions. Two classes of accuracy exist for graduated cylinders. Class A has double the accuracy of class B. [4] Cylinders can have single or double scales. Single ...

3. Beaker (laboratory equipment) - Wikipedia

   en.wikipedia.org/wiki/Beaker_(laboratory_equipment)

   For instance, a 250 mL beaker might be marked with lines to indicate 50, 100, 150, 200, and 250 mL of volume. These marks are not intended for obtaining a precise measurement of volume (a graduated cylinder or a volumetric flask would be a more appropriate instrument for such a task), but rather an estimation. Most beakers are accurate to ...

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. Wet chemistry - Wikipedia

   en.wikipedia.org/wiki/Wet_chemistry

   Wet chemistry commonly uses laboratory glassware such as beakers and graduated cylinders to prevent materials from being contaminated or interfered with by unintended sources. [3] Gasoline, Bunsen burners , and crucibles may also be used to evaporate and isolate substances in their dry forms.

6. Graduated pipette - Wikipedia

   en.wikipedia.org/wiki/Graduated_pipette

   Graduated pipettes are considered to be more precise than the Pasteur pipette. They have tolerances that range from ±0.6% to ±0.4% of the nominal volume when measured at 20 °C (68 °F). Graduated pipettes are manufactured according to ISO specifications for accuracy and the arrangement of the graduations. Grade A and AS pipettes have the ...

7. Erlenmeyer flask - Wikipedia

   en.wikipedia.org/wiki/Erlenmeyer_flask

   Method of swirling an Erlenmeyer flask during titration. The slanted sides and narrow neck of this flask allow the contents of the flask to be mixed by swirling, without risk of spillage, making them suitable for titrations by placing it under the buret and adding solvent and the indicator in the Erlenmeyer flask.
