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.
Caesium fluoride sample on a 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.
(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]
A funnel (E) contains a sample of soil or leaf litter (D), and a heat source (F), in this case an electric lamp (G), heats the sample. Animals escaping from the desiccation of the sample descend through a filter (C) into a preservative liquid (A) in a receptacle (B).
The greenish tint of this float glass is from iron impurities. Low-iron glass does not exhibit this color. Low-iron glass is a type of high-clarity glass that is made from silica with very low amounts of iron.
Laboratory ovens are a common piece of equipment that can be found in electronics, materials processing, forensic, and research laboratories. These ovens generally provide pinpoint temperature control and uniform temperatures throughout the heating process.
Corning Glass Works has reproduced a blank of a material of similar chemical composition and internal structure, which displays under reflected and transmitted light the same "Lycurgus effect" of green to red colour change as the Lycurgus cup material does. [21]
