Especially borosilicate glass, pioneered by Otto Schott, or sodalime glass are preferred glass types for scientific experiments and other work in science, especially in chemistry and biology laboratories. Applications Glass use in laboratory applications is not as commonplace as it once was because of cheaper, less breakable, plasticware; however, certain applications still require glassware because glass is relatively inert, transparent, heat-resistant, and easy to customize. There are several types of glass, each used for different purposes. Borosilicate glass, which is commonly used in reagent bottles, can withstand thermal stress. Quartz glass, which is common in cuvettes, can withstand high temperatures and is transparent in certain parts of the electromagnetic spectrum. Darkened brown or amber (actinic) glass, which is common in dark storage bottles, can blockultraviolet and infrared radiation. Heavy-wall glass, which is common in glass pressure reactors, can withstand pressurized applications. There are many different kinds of laboratory glassware items. Examples of glassware containers include: Beakers are simple cylindrical shaped containers used to hold reagents or samples. Flasks are narrow-necked glass containers, typically conical or spherical, used in a laboratory to hold reagents or samples. Examples flasks include the Erlenmeyer flasks and Florence flasks. Bottles are containers with narrow openings generally used to store reagents or samples. Small bottles are called vials. Jars are cylindrical containers with wide openings that may be sealed. Bell jars are used to contain vacuums. Watch glasses are shallow glass dishes used as an evaporating surface or to cover a beaker. Test tubes are used by chemists to hold, mix, or heat small quantities of solid or liquid chemicals, especially for qualitativeexperiments and assays Desiccators of glass construction are used to dry materials or keep material dry. Glass evaporating dishes are used to evaporate materials. Microscope slides are thin strips used to hold items under a microscope. Glass petri dishes are used to culture living cells. Examples of glassware used for measurements include: Graduated cylinders are cylindrical containers used for volumetric measurements. Burettes are used to disperse precise amounts of liquid reagents. Glass pipettes are used to transfer precise quantities of fluids. Glass Ebulliometers are used to accurately measure the boiling point of liquids. Other examples of glassware includes: Glass tubes are cylindrical pieces of glassware used to hold or transport fluids. Stirring rods are used to mix chemicals. Funnels are used to get materials through a narrow opening. Condensers are used to cool hot liquids or vapors. Glass retorts are used for distillation. Drying pistols are used to free samples from traces of water, or other impurities. Most laboratory glassware is currently mass-produced, but large laboratories may employ a glass blower to construct specialized pieces. This construction forms a specialized field of glassblowing requiring precise control of shape and dimension. In addition to repairing expensive or difficult-to-replace glassware, scientific glassblowing commonly involves fusing together various glass partssuch as glass joints and tubing, stopcocks, transition pieces, and/or other glassware or parts of them to form items of glassware, such as vacuum manifolds, special reaction flasks, etc. Various types of joints and stopcocks are available separately and come fused with a length of glass tubing, which a glassblower may use to fuse to another piece of glassware.
