Over Head Stirrers
An overhead stirrer is a sort of mechanical stirrer, used for stirring solutions within the chemistry lab, though for general functions, magnetic stirrers are more commonly employed as they're easier to each use and keep. However, overhead stirrers are more appropriate when stirring massive volumes of solution or thick suspensions, as well as dissolving massive amounts of stable in a solvent. cNEMKOus VELP Scientifica Overhead Stirrers The cNEMKOus mark ensures this product is designed and manufactured in compliance with the International Directive on Safety IEC/EN . The cNEMKOus mark has the identical legal status as another NRTL/SCC accredited marks, for U.S. and Canada. Easy to use general objective overhead stirrer appropriate for everyday laboratory use with aqueous and low viscosity liquids corresponding to light oils, as much as 15 litres.
From magnetic stirrer to overhead, high shear, and even to reactor size. EUROSTAR energy control-visc P1 Overhead Mixer Powerful, digital laboratory stirrer for tasks up to the excessive viscosity vary.
With good velocity control and overload safety often discovered in additional superior fashions, the SS10 represents wonderful value for cash. Some overhead stirrers have a characteristic that reduces the power if a certain torque is reached.
They tried to market a large 220 volt wall unit as a home microwave oven in 1955 for a price of US$1,295 ($12,000 in 2019 dollars), nevertheless it did not sell well. In 1945, the heating effect of a high-power microwave beam was by accident found by Percy Spencer, an American self-taught engineer from Howland, Maine. Employed by Raytheon on the time, he observed that microwaves from an active radar set he was engaged on started to soften a chocolate bar he had in his pocket. The first meals intentionally cooked with Spencer's microwave was popcorn, and the second was an egg, which exploded within the face of one of the experimenters. To confirm his finding, Spencer created a high density electromagnetic area by feeding microwave energy from a magnetron right into a metal box from which it had no approach to escape.
The IKA EUROSTAR digital and management series feature a velocity display and overload safety. The control model is designed with a removable wi-fi controller (WiCo) and is supplied with a torque development and thin-film transistor (TFT) display, RS232, and USB interface. In addition, purchasers are able to replace their product’s firmware on-line.

In turntable-geared up ovens, more even heating will take place by putting meals off-middle on the turntable tray instead of exactly within the middle, as this can lead to more even heating of the food all through. In 1947, Raytheon built the 'Radarange', the first commercially available microwave oven. It was nearly 1.eight metres (5 ft eleven in) tall, weighed 340 kilograms (750 lb) and value about US$5,000 ($fifty seven,000 in 2019 dollars) each. It consumed 3 kilowatts, about thrice as a lot as right now's microwave ovens, and was water-cooled.
An early Radarange was installed (and stays) within the galley of the nuclear-powered passenger/cargo ship NS Savannah. An early commercial model launched in 1954 consumed 1.6 kilowatts and offered for US$2,000 to US$3,000 ($19,000 to $29,000 in 2019 dollars). Raytheon licensed its expertise to the Tappan Stove firm of Mansfield, Ohio in 1952.
Designed to optimise complicated stirring purposes, IKA’s overhead stirrer expertise provides a solution to laboratory stirring and mixing needs, from low to high-viscosities. Cloud enabled overhead stirrers with three.5' TFT show, technique setting, precise torque measurement, temperature monitoring, vibration sensor, timer, Wi-Fi connection to address essentially the most demanding functions. Mixing and stirring is the commonest application in a laboratory and even in different trade corresponding to for Bio-medication, Food, Daily chemical compounds, Fine chemicals, Petrochemicals. Mixing and stirring goes a long way from minor purposes to industrial measurement.
When meals was placed in the field with the microwave energy, the temperature of the food rose quickly. On 8 October 1945, Raytheon filed a United States patent software for Spencer's microwave cooking course of, and an oven that heated food utilizing microwave vitality from a magnetron was soon placed in a Boston restaurant for testing.
