Your TIMS system is special, so why get it serviced by non-specialist engineers? 

Service Plans

Whether you require a one-off PM visit or a multi-year service plan, Isotopx provides versatile and cost effective solution to your needs. Service plan customers always receive priority service and can additional benefits such as discounted on-site support and free software upgrades. If you need to maximise up-time then an Isotopx service plan is the best way to guarantee the fastest response from the most experienced engineers.

Example service plans


Isotopx carry spares for all of our recent instruments as well as many older VG systems. As instruments become older it inevitably gets harder to find replacement parts, particularly electrical and computer components, many of which have long become obsolete.

Recognising the importance of maintaining older isotope ratio mass spectrometers, Isotopx has a number of programs in place designed to identify key components in older systems and make sure that modern replacements are available. At the same time we endeavour to make sure that as far as possible, the latest developments on our newest machines are available as upgrades on older systems. We recognise the magnitude of your investment and as far as possible will ensure it is maximized.
