Get ready for some hands-on chemistry! Studying chemical compounds in a textbook is one thing, but working with them in the lab is a totally different experience. Have you ever wondered how to identify an unknown substance? Or how to determine if it's a salt and what the cation and anion are? By performing a series of chemical reactions in a test tube, you can figure out the chemical composition of a substance.

Nonspecific interactions between individual macro-molecules and their immediate surroundings (`background interactions') within a medium as heterogeneous and highly volume occupied as the interior of a living cell can greatly influence the equilibria and rates of reactions in which they participate. Background interactions may be either repulsive, leading to preferential size-and-shape-dependent exclusion from highly volume-occupied elements of volume, or attractive, leading to nonspecific associations or adsorption. Nonspecific interactions with different constituents of the cellular interior lead to three classes of phenomena: macromolecular crowding, confinement and adsorption. Theory and experiment have established that predominantly repulsive background interactions tend to enhance the rate and extent of macromolecular associations in solution, whereas predominately attractive background interactions tend to enhance the tendency of macromolecules to associate on adsorbing surfaces. Greater than order-of-magnitude increases in association rate and equilibrium constants attributable to background interactions have been observed in simulated and actual intracellular environments.

Test tubes may be used as reaction vessels, short-term storage containers (when stoppered), or for heating small amounts of substances. An inverted test tube ...
Test Tubes Test tubes (or culture tubes) are common chemical vessels consisting of a length of glass (or sometimes plastic) tube open at the top and sealed at the bottom. They come in a variety of diameters and lengths and may have a flared rim or be rimless (straight). Test tubes may be used as reaction vessels, short-term storage containers (when stoppered), or for heating small amounts of substances. An inverted test tube filled with water may be used to trap gases produced during a chemical reaction. Test tubes used in the chemistry lab are usually made from thermally stable borosilicate glass so they can withstand high temperatures and corrosive chemicals. During heating, test tubes are typically held with a clamp or tongs placed approximately 1cm below the mouth of the test tube. The tube is tilted at an angle with the mouth pointing away from all people in the lab. Tilting the tube allows the bottom to be heated to very high temperatures while the top of the tube remains fairly cool.
