A KT gusset plate connects several members together through one gusset plate. The gusset plate is welded to a beam, and then two or three columns, beams, or truss chord are connected to the other side of the gusset plate through bolts or rivets or welds. [3] A uniform force bracing connection connects a beam, column, and one other member. The ...
A fishplate, splice bar or joint bar is a metal connecting plate used to bolt the ends of two rails into a continuous track. The name is derived from fish, [1] a wooden reinforcement of a "built-up" ship's mast that helped round out its desired profile. [2] The top and bottom faces taper inwards along their short dimensions to create an even ...
These tubes should be used with care when measuring drug or hormone levels because the drug or hormone may diffuse from the serum into the gel, causing a reduction in measured level.
Laboratory glassware. Laboratory glassware is a variety of equipment used in scientific work, traditionally made of glass. Glass may be blown, bent, cut, molded, or formed into many sizes and shapes. It is commonly used in chemistry, biology, and analytical laboratories.
A mechanical splice is a junction of two or more optical fibers that are aligned and held in place by a self-contained assembly (usually the size of a large carpenter's nail). [ 1] The fibers are not permanently joined, just precisely held together so that light can pass from one to another. This impermanence is an important advantage over ...
Looking at the bottom of a socket, or, equivalently, a tube from its bottom, the pins were numbered clockwise, starting at an index notch or gap, a convention that has persisted into the integrated circuit era. In the 1930s, tubes often had the connection to the control grid brought out through a metal top cap on the top of the tube. This was ...
Glass tube. Glass tubes are mainly cylindrical hollow-wares. Their special shape combined with the huge variety of glass types (like borosilicate, flint, aluminosilicate, soda lime, lead or quartz glass), allows the use of glass tubing in many applications. For example, laboratory glassware, lighting applications, solar thermal systems and ...
A microplate, also known as a microtiter plate, microwell plate or multiwell, [1] is a flat plate with multiple "wells" used as small test tubes. The microplate has become a standard tool in analytical research and clinical diagnostic testing laboratories. A very common usage is in the enzyme-linked immunosorbent assay (ELISA), the basis of ...
