This Regulation mainly concerns manufacturers of water pumps placing these products on the European market. However customers may also be affected. Europump has created a guideline to clarify questions which may arise with the entry into force of the water pumps Regulation EU 547/2012. [ 9 ]
The turbomolecular pump can be a very versatile pump. It can generate many degrees of vacuum from intermediate vacuum (≈10 −2 Pa) up to ultra-high vacuum levels (≈10 −8 Pa). Multiple turbomolecular pumps in a lab or manufacturing-plant can be connected by tubes to a small backing pump.
They had offerings over a broad range of chemical analysis equipment, with a particular focus on Information Rich Detection [clarification needed] and Vacuum technology. Varian was spun off from Varian Associates in 1999 and was purchased by Agilent Technologies in May 2010 for $1.5 billion, or $52 per share.
After the war, some of the inventions found new applications. The first transistor radio was released in 1954, and its manufacturing process made use of vacuum pumps. [43] The first integrated circuit or “chip” came to the market at the end of the 1950s, and vacuum pumps again played an important role in their production. These early ...
An oil diffusion pump is used to achieve higher vacuum (lower pressure) than is possible by use of positive displacement pumps alone. Although its use has been mainly associated within the high-vacuum range, down to 1 × 10 −9 mbar (1 × 10 −7 Pa), diffusion pumps today can produce pressures approaching 1 × 10 −10 mbar (1 × 10 −8 Pa) when properly used with modern fluids and accessories.
The Responsible Marketing Blog recently blew the whistle on another 'vanity award', the prestigious-sounding U.S. Local Business Association's "Best of" award. This so-called organization makes ...
