2. Beaker (laboratory equipment) - Wikipedia

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

   (A) A low-form or Griffin form beaker (B) A tall-form or Berzelius beaker (C) A flat beaker or crystallizer Philips beaker which can be swirled like a conical flask. Standard or "low-form" (A) beakers typically have a height about 1.4 times the diameter. [3] The common low form with a spout was devised by John Joseph Griffin and is therefore ...

3. Weighing bottle - Wikipedia

   en.wikipedia.org/wiki/Weighing_bottle

   Weighing bottles are glass laboratory equipment used for precise weighing of solids. Most of the glass used in the bottles is thin and fragile glass, but sometimes they are also made of ceramics or plastics. Dishes tend to have many different shapes. The three most popular are: Flat glass dish, which is equipped with a ground cover.

   en.wikipedia.org/wiki/Laboratory_glassware

   Glass evaporating dishes, such as watch glasses, are primarily used as an evaporating surface (though they may be used to cover a beaker.) The Petri dish is a flat dish filled with a nutritious gelatin that allows for microorganisms to quickly grow, its named after its inventor Julius Petri in the 1880s.

5. Borosilicate glass - Wikipedia

   en.wikipedia.org/wiki/Borosilicate_glass

   Guitar slide made of borosilicate glass. Borosilicate glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. Borosilicate glasses are known for having very low coefficients of thermal expansion (≈3 × 10 −6 K −1 at 20 °C), making them more resistant to thermal shock than any other common glass.

6. Pyrex - Wikipedia

   en.wikipedia.org/wiki/Pyrex

   A PYREX measuring cup manufactured c. 1980, featuring graduations in both U.S. and metric units. Pyrex (trademarked as PYREX and pyrex) is a brand introduced by Corning Inc. in 1915, initially for a line of clear, low-thermal-expansion borosilicate glass used for laboratory glassware and kitchenware.

7. Watch glass - Wikipedia

   en.wikipedia.org/wiki/Watch_glass

   A watch glass is a circular concave piece of glass used in chemistry as a surface to evaporate a liquid, to hold solids while being weighed, for heating a small amount of substance, and as a cover for a beaker. When used to cover beakers, the purpose is generally to prevent dust or other particles from entering the beaker; the watch glass does ...
