Design elements - Laboratory equipment

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]

"A classroom or schoolroom is a room dedicated primarily to teaching or learning activities. Classrooms are found in educational institutions of all kinds, including public and private schools, home schools, corporations, and religious and humanitarian organizations. ...
For lessons that require specific resources or a vocational approach different types of classrooms both indoors and outdoors are used. This allows for learning in an authentic context that fosters the natural development of the particular vocational skill. This is known as situated learning. Classrooms can range from small groups of five or six to big classrooms with hundreds of students. A large class room is also called a lecture hall. A few examples of classrooms are computer labs which are used for IT lessons in schools, gymnasiums for sports, and science laboratories for biology, chemistry and physics. There are also small group classrooms where students learn in groups of about 7 ...
A university classroom with permanently installed desk-chairs, green chalkboards, and an overhead projector.
Most classrooms have a large writing surface where the instructor or students can share notes with other members of the class. Traditionally, this was in the form of a blackboard but these are becoming less common in well-equipped schools because of new alternatives like flipcharts, whiteboards and interactive whiteboards. Many classrooms also have TVs, maps, charts, Pencils, books, monographs and LCD projectors for presenting information and images from a computer." [Classroom. Wikipedia]
