Working with ion getter pumps: everything you need to know

Ion getter pumps (also called sputter ion pumps or simply ion pumps) produce ultra-high vacuum (UHV) without the aid of moving parts or valves. This makes them highly effective, quiet and low maintenance.

Choosing between different types of vacuum pumps

What do you need to consider when choosing vacuum pumps?

Anyone without a deep understanding or knowledge of pumps might think that vacuum generation is simply a question of “plugging in a pump”, starting it up and waiting for the vacuum to drop to the required level.

Understanding vacuum pressure measurement

When it comes to choosing a vacuum gauge, understanding the application and vacuum pressure measurement required is crucial to making the right choice.

But while pressure measurement plays an important role in all vacuum applications, there’s no universal vacuum gauge that will respond accurately throughout the range from atmospheric pressure to 10-12 mbar.

Working with turbomolecular vacuum pumps

How does a turbomolecular pump work? 

Turbomolecular pumps (TMPs) are kinetic vacuum pumps which operate using a very fast spinning rotor (usually rotating at between 24,000 and 90,000 RPM). Their typical operating pressures are in the high to ultra-high pressure range between 10-3 and 10-11 mbar, employing pumping speeds of between 10 and 4,000 l/s.

How to find the right vacuum pump system for your lab work

Laboratory technicians and scientists regularly use vacuum pumps (frequently of the bench-top variety) for a range of tasks including aspirating/filtering, controlling or inducing solvent evaporation in concentrators, as well as in gel driers, vacuum ovens, desiccators and rotary evaporators.

Eight top tips for working with oil-sealed rotary vane pumps

Rotary vane pumps are considered wet, positive displacement pumps, with the term “wet” denoting that the gases being pumped are exposed to oil. The significant characteristic of oil sealed rotary vane (OSRV) pumps is the use of oil as a sealant, which is not found in ‘dry’ pumps.
