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.
Varian, Inc. was one of the largest manufacturers of scientific instruments for the scientific industry. [1] They had offerings over a broad range of chemical analysis equipment, with a particular focus on Information Rich Detection [clarification needed] and Vacuum technology.
The equipment is composed of a tool, a press, an injector, and a vacuum pump. [4] The key factors in the SQRTM process include precision machined closed mold tooling, high pressure presses, a high vacuum applied to the tool interior, and precise control of heating platens, injected resin volume, heat, and pressure.

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 ...

The Roots blower is one example of a vacuum pump. A vacuum pump is a type of pump device that draws gas particles from a sealed volume in order to leave behind a partial vacuum. The first vacuum pump was invented in 1650 by Otto von Guericke, and was preceded by the suction pump, which dates to antiquity. [1]
