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.
Beaker (glassware) Many of these flasks can be wrapped in a protective outer layer of glass, leaving a gap between the inner and outer walls. These are called jacketed flasks; they are often used in a reaction using a cooling fluid.
(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 sometimes called a Griffin beaker.
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 ...
A couple of weighing bottles. 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.
The appearance of the Hedwig beakers resembles rock crystal, or quartz, and they are made of soda ash glass, which is composed of plant ash and quartz sand. [9] Although no two look exactly alike, all have a similar conical shape, thick walls, and wheel-cut ornament. [10]
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.
