	Liebig condenser - Wikipedia, the free encyclopedia
		The Liebig condenser is a piece of laboratory equipment where a straight glass pipe goes through a water jacket (a glass cylinder through which water constantly flows).
		The Liebig condenser is much more efficient than a simple retort due to its use of liquid cooling.
		Though named after the German chemist Justus Baron von Liebig, he cannot be given credit for having invented it because it was already in use for some time before him.

	Purification of Water for Scientific Purposes - Arasi Lawrence Company
		Distilled water can be made by means of an apparatus comprising a distilling flask and Liebig condenser, but partly on account of the slight solvent action of water on the glass, and partly because of the considerable quantities required in the average laboratory, some form of water-still designed for the purpose is usually employed.
		Such a still is usually made of copper plated with tin, and the principle involved in its use is identical with that of the simple distillation apparatus using a Liebig’s condenser and distillation flask.
		The apparatus used for the purpose is called a still ; if the condenser were sloped the other way, so that the condensed liquid ran down to the left into a vessel placed to collect it there, and not back into the boiler, then the arrangement would form a still.

	Spinning band fractionating column - Patent 4770746
		Reflux is controlled by an angled drip edge on a rotatable condenser column that passes a portion of dripped condensate to a collecting spout with the portion varying as rotation of the condenser column brings the drip from said edge closer or further from center opposition with the spout.
		The present invention provides a spinning band fractionating column in which a magnetic material is incorporated in the bottom end of the band so that, when the column apparatus is placed on a conventional laboratory magnetic stirring plate, the band is caused to spin by the rotating field from the plate.
		Spinning band fractionating column apparatus is disclosed having a spinning band formed with a magnet embedded in its bottom end in the manner of a magnetic stirring vane for rotation by a rotating external magnetic field at the bottom of the apparatus.

	Re: Which is more pure distilled or deionized water?
		Distillation entails converting water from the liquid state to the gaseous state and back to liquid again in an apparatus called a "still," comprising a boiling vessel to vaporize the water and a cooling unit ("condenser") to return the water to the liquid state.
		Water we drink need not be as pure as water used for some laboratory purposes, but each laboratory has to adjust its purification system to the intended use of the water — and then devise a monitoring system to ensure that the required purification is being attained.
		Deionization entails removal of electrically charged (ionized) dissolved substances by binding them to positively or negatively charged sites on a resin as the water passes through a column packed with this resin.

	Extreme Ultraviolet Lithography
		The continued development of extreme ultraviolet (EUV) lithography technology is a result of a partnership between LLNL, Lawrence Berkeley National Laboratory, Sandia National Laboratory, and an industry consortium composed of AMD, Intel, and Motorola.
		These optics are used in the condenser to collect the EUV radiation from the source and to focus the radiation onto the reflective reticle in the camera to reproduce an image of the mask pattern onto the wafer.
		Each of the mirrors must be manufactured and assembled in the lithography subsystem to maximize the imaging efficiency and reduce distortion.

	Information Bridge: DOE Scientific and Technical Information
		This study is the result of the cooperative research and development agreement (CRADA) between Oak Ridge National Laboratory and E.I. Du Pont De Nemours and Company, Inc., (CRADA No. 92-0161) for testing the use of heat exchangers as the evaporator and condenser in an air-conditioning rig.
		Temperature glide for ternary mixture, for both evaporator and condenser, was clearly evident, but not as pronounced as expected because of the pressure drop (and thus the temperature drop) along the coils.
		Compared with R-22 operation, operation with ternary mixture results in slightly higher compressor discharge pressure, lower compressor discharge temperature, slightly lower compressor power consumption, and a higher compressor high-low pressure ratio.

	THE FARNSWORTH MULTIPACTOR TUBE
		Previous laboratory tests proved that the tube is capable of generating oscillations of any desired frequency throughout the range from 200 kilocycles to 60 megacycles, these limits being set only by the dimensions of the available tuned circuits.
		When used as an amplifier, a high frequency voltage is applied to the cathode terminals and a D.C. voltage is applied to the anode terminal to hold it at a positive potential with respect to the cathodes, which are shunted by a coil and variable condenser in parallel.
		Consideration of the manner in which Farnsworth's tube functions as an amplifier shows that it conforms to this requirement when connected to a resonant circuit which is tuned to a frequency whose half-period is equal to an electron's time of transit, as determined by the frequency of the oscillations applied to the cathodes.

	Microphone - Wikipedia, the free encyclopedia
		In a capacitor microphone, also known as a condenser microphone, the diaphragm acts as one plate of a capacitor, and the vibrations produce changes in the distance between the plates.
		Capacitor microphones can be expensive and require a power supply, commonly provided from mic inputs as phantom power, but give a high-quality sound signal and are now the preferred choice in laboratory and studio recording applications.
		In a dynamic microphone a small movable induction coil, positioned in the magnetic field of a permanent magnet, is attached to the diaphragm.

	The Case of the Cracked Water Pump
		According to this theory, a reduction in load caused a control valve on the auxiliary condenser of the heat-recovery chiller to close.
		An engineering analysis that identifies the likely cause of failure before destructive testing often is helpful, as appropriate laboratory tests can be selected to provide the information needed to confirm the cause of failure.
		By modeling the pump as a pressurized cylinder and calculating hoop stress, it was determined that the system pressure would have had to have reached 1750 psi for the load to have approached the 30,000 psi required to break the cast iron.
