Chemistry Symbols and Meanings

The vector stencils library "Laboratory equipment" contains 31 clipart icons of chemical laboratory equipment and labware for drawing part assembly and mounting schemes of glassware apparatus in chemical experiment diagrams and illustrations.
"Laboratory 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. ...
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. The type of glass used is dependent on the application. 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 block ultraviolet and infrared radiation. Heavy-wall glass, which is common in glass pressure reactors, can withstand pressurized applications." [Laboratory glassware. Wikipedia]
