Frequently Asked Questions

We aim to answer all your product questions, if the answer you are looking for isn't here then complete this form

Sample Manipulation

What manipulator should I purchase for Synchrotron applications?

The Omniax is our flagship manipulator, designed for high resolution & repeatability. This manipulator is extremely rigid and can take up to a 20kg payload capacity. For more information visit the product page.

How do I replace by worm & wheel drive?

We have an assembly guide to explain how to replace your worm and wheel drive on your current manipulator. Please download the assembly guide here.

How do I maintain my manipulator?

All our sample manipulators will require a service after a number of years.

It's great to keep your product in top shape by either contacting us for an RMA to return the product for a paid service. Or if you want to do some maintenance in the lab, download the Omniax Operating Instructions for how to maintain your manipulator. If you have any specific questions which are not included in the manual, please contact

Vacuum Chambers

What material should I design my vacuum chamber in?

The material for your chamber will depend on your specific application. Mu-metal is commonly used for electron spectroscopy applications to minimise external magnetic interference which can distort the trajectories of electron leading to inaccuracies in spectroscopy measurements. VACGEN typically manufacture vacuum chambers in 304/316 LN stainless steel, aluminium and mu-metal. Contact one of our engineers today <ahref=""> for design assistance.

> What are typical vacuum chamber applications?

Could VACGEN assist with the design of my vacuum chamber?

Yes, our expert vacuum chamber engineers can walk you through the steps for designing a chamber. If you have a sketch or 2D drawing then please send us your requirements to and an engineer will be in contact to discuss your requirements.

Vacuum Drives & Motion

My wobblestick is leaking, what do I do?

If you have encountered a leak with your wobble stick, please contact and the sales team will provide you with a repair cost estimation quote and RMA decontamination form. Once your product has been returned for assessment, we will contact you to go ahead with the replacement bellows operation.

How do I replace the seals on my DPRF?

All our components require routine maintenance and replacing or cleaning the seals on your DPRF or RP100 rotary platform is a relatively straight forward task. We have an assembly guide to walk you through the steps of changing and/or cleaning your DPRF and RP100 seals. Please download the assembly guide below.
