lab glassware refers to a variety of equipment, traditionally made of glass, used for scientific experiments and other work in science, especially in chemistry and biology laboratories. some of the equipment is now made of plastic for cost, ruggedness, and convenience reasons, but glass is still used for some applications because it is relativelyinert, transparent, more heat-resistant than some plastic up to a point, and relatively easy to customize. borosilicate glasses—formerly called pyrex—are often used because they are less subject tothermal stress. for some applications quartz is used for its ability to withstand high temperatures or its transparency in certain parts of the "electromagnetic spectrum">electromagnetic spectrum. in some applications, especially some storage bottles, darkened brown lab glassware is used to keep out much of the outside light so that the effect of light on the contents inside is minimized. special-purpose materials are also used; for example, hydrofluoric acid is stored and used inpolyethylene containers because it attacks glass.
