A beaker is a simply container commonly made of glass (especially borosilicate glass, these days), used for stirring, mixing and heating liquids used in laboratories. They are generally cylindrical in shape, with a flat bottom and a lip for pouring. This has been also called the “Griffin” form. These are the most universal characteristics and are used for various purposes, from preparing solutions and decanting supernatant fluids to simple reactions. Many also have a small spout to aid pouring. Beakers are often graduated, that is, marked on the side with lines indicating the volume contained.
Test tubes are also known as culture tubes or sample tubes, which is a common piece of laboratory glassware consisting of a finger-like length of glass or clear plastic tubing, open at the top, usually with a rounded U-shaped bottom. Large test tubes designed specifically for boiling liquids are called boiling tubes. These are commonly used for chemical reactions.

A graduated cylinder is also known as a measuring cylinder and is a piece of laboratory used to take accurate measurements of the volume of an object. Often, largest cylinders are made of polypropylene because of its excellent chemical resistance, OR polymethylpentene for its clarity. These characteristics make them lighter to ship and less fragile than glass. Temperatures over 160 °C / 320 °F, may affect accuracy and can warp or damage polypropylenecylinders.
A stirring rod is a piece of laboratory equipment used to mix chemicals and liquids for laboratory purposes. They are usually made of solid glass, about the thickness and slightly longer than a drinking straw.
Florence and Erlenmeyer flasks are practically the same except for the shape, and the uses. Florence flasks are generally used for boiling substances; and Erlenmeyer flasks are commonly used for titration, especially of ph. Erlenmeyer are named after the scientist (Emil) who created them in 1861. Florence are named after the Italian city Florence.
There are many different kinds of funnels that have been adapted for specialized applications in the laboratory.Filter funnels, thistle funnels (shaped like thistle flowers), and dropping funnels have stopcocks which allow the fluids to be added to a flask slowly. For solids, a powder funnel with a wide and short stem is more appropriate as it does not clog easily.
When used with filter paper, filter funnels, Buchner and Hirsch funnels can be used to remove fine particles from a liquid in a process called filtration. For more demanding applications, the filter paper in the latter two may be replaced with a sintered glass frit.
Separatory funnels are used in liquid-liquid extractions.
Glass is the material of choice for laboratory applications due to its inertness compared with metals or plastics. However, plastic funnels made ofnonreactive polyethylene are used for transferring aqueous solutions. Plastic is most often used for powder funnels which do not come into contact with solvent in normal use.
Hyneman was born in Marshall, Michigan and raised in Columbus, Indiana. Describing his early life, he said 'I was a problematic kid, to be sure. I left home when I was 14 and hitchhiked all over the country.'
He earned a degree in Russian linguistics from Indiana University. A variety of careers fill his resume, including scuba diver, wilderness survival expert, boat captain, linguist, pet shop owner, animal wrangler, machinist, concrete inspector, and chef. He apparently has a mild case of acrophobia (fear of heights), as mentioned in the 'Hammer Drop' episode segment of Mythbusters.
A distinctive part of his appearance is his dark beret, white long-sleeve button up shirt over a black t-shirt, no-rim glasses, and, occasionally, sunglasses. This, along with his walrus-style moustache and deep voice, are constant subjects for jokes by co-host Adam Savage and other team members. A sign hanging in his workshop reading 'Clean Up or Die', visible in several episodes, expresses his desire to keep the shop clean and tidy.
Hyneman's demeanor on MythBusters is calm, logical and no-nonsense, in contrast to Savage's more animated, impulsive and energetic persona. Hyneman is often exasperated by Savage's antics and he sometimes squabbles with him on how to test myths. Thetwo often have completely different ideas for performing experiments and building devices. Hyneman's ideas tend to be more simplified, and he has been heard saying 'keep it as simple as possible' and 'more grunt, less elegance'. This has led to competitions between the two presenters when testing some myths, such as testing the Goldfish Memory myth and Hoverboard myth.
His notable achievements in commercials include the can-spitting vending machine seen in 7 Up commercials, and his patented two-wheeled football shoe from Nike Lab commercials.
James Franklin 'Jamie' Hyneman (born September 25, 1956) is an American special effects expert, best known for being the co-host of the television series MythBusters. He is also the owner of M5 Industries, the special effects workshop where MythBusters is filmed. He is known among Robot Wars devotees for his robot entry, Blendo, which, for a time, was deemed too dangerous for entry in the competition. He is one of the designers of the aerial robotic camera system Wavecam, used in sports and entertainment events. On May 16, 2010, he delivered the commencement address and received a Doctorate of Engineering, honoris causa, from Villanova University.
