Ultra-high Vacuum Fittings: What Are Flanges Used For?

Despite how commonplace vacuum technology is, it can be difficult to know what fittings and parts are needed to create ideal vacuum environments. Here, we explore what vacuum flanges are and what they may be used for. Let’s start by looking at how flanges are used to create vacuum systems.

What Are the 5 Signs of Vacuum Pump Failure?

Even the most well-constructed vacuum pump can fail after extended use. In industrial applications, for instance, the downtime resulting from pump failures can be prohibitively expensive — especially if it forces production to grind to a halt.

How Vacuum Technology Supports COVID-19 Vaccine Efficacy

The storage and transport of COVID-19 vaccines has to be managed in a cold chain, with the first approved vaccine by Pfizer-BioNtech requiring storage temperatures of -70 C. Besides using dry ice (solid carbon dioxide at -75.8 C), Vacuum Insulated Panels and vacuum insulation have become attractive solutions.

The key working principles of High and Ultra-High vacuum pumps

High Vacuum (HV) and Ultra-High Vacuum (UHV) levels can only be effectively and efficiently obtained by using a main pump that has the functional capabilities. Choosing which pump to use depends on a number of factors, such as noise/vibration, cost (initial and on-going), tolerance to contamination, footprint, maintenance schedules, and resilience to shock.

100 Years of the Holweck Vacuum Pump

 

2020 marks the centenary of the development of the Holweck pump by the French physicist Fernand Holweck. As well as a stand-alone pump the Holweck design is used as a compound pumping stage in the widely employed TURBOVAC, nEXT and STP pumps. In this respect the Holweck design has been utilised to make significant advancements and improvements to the development of turbomolecular pumps over the last half century.

How has COVID-19 affected the US vacuum technology industry?

For business and organisations in the vacuum technology space, COVID-19 has changed the way in which they operate indefinitely – with many experiencing the effects in different ways. It has, without a doubt, been a harsh and challenging year, but signs of recovery are on the horizon as government-imposed lockdowns ease and many of these businesses and organisations resume (in some way) operations. .
