TaqMan probes are hydrolysis probes that are designed to increase the specificity of quantitative PCR. The method was first reported in 1991 by researcher Kary Mullis at Cetus Corporation, [ 1 ] and the technology was subsequently developed by Hoffmann-La Roche for diagnostic assays and by Applied Biosystems (now part of Thermo Fisher ...
The well position is also standardized, but only for 96- , 384-, and 1536-well plates. These are generally well followed by manufacturers: Well Positions [16] [17] 96-well plates have a 9 mm well-to-well spacing, 384-wells a 4.5 mm spacing, and 1536-wells a 2.25 mm spacing. A notable characteristic is that the well array is symmetrical when the ...
I designed the figure from an overlay of a 384-well plate manufacturer technical drawing. Designed in Inkscape. The Inkscape "Tiled clone" tool where the percentage row/column shift was calculated by (well spacing/well width-1.00)*100 (in this case, 12.5%), was essential to producing regularly spaced wells.
Plate readers, also known as microplate readers or microplate photometers, are instruments which are used to detect biological, chemical or physical events of samples in microtiter plates. They are widely used in research, drug discovery , [ 1 ] bioassay validation, quality control and manufacturing processes in the pharmaceutical and ...
The 1 well rack is designed to hold only one test tube or any tube that fits in the space. It is normally made of epoxy-coated steel wire [ 6 ] but can also be made of polystyrene. The racks made from polystyrene are friction-fit and can only hold tubes that match in size to the rack.
The plate geometry is one of the most important factors in heat transfer and pressure drop in plate heat exchangers; however, such a feature is not accurately prescribed. In the corrugated plate heat exchangers, because of narrow paths between the plates, there is a large pressure capacity and the flow becomes turbulent along the path.
A clamp holder or clamp fastener is a piece of laboratory apparatus that is used to secure laboratory clamps, such as extension-type utility clamps, or other attachments to a retort stand or lab frame. [1] The material can be made up of brass, cast iron, stainless steel, aluminium or nickel-plated zinc. [2]
30,000 m 3 (1,100,000 cu ft) blast furnace gas holder at Rautaruukki Steel in Finland. A gas holder or gasholder, also known as a gasometer, is a large container in which natural gas or town gas (coal gas or formerly also water gas) is stored near atmospheric pressure at ambient temperatures. The volume of the container follows the quantity of ...
