No. Especially since dealing with mercury, the MVI should only be opened by an Ion Science Ltd Authorised Service Centre, trained to service the MVI. Any instrument opened by unauthorized persons will void the warranty, and may put users at risk. If you believe that there is an issue with your unit, please return it to your nearest MVI authorized Service Centre for inspection. If you can’t find one in your area you will need to return your instrument to the Ion Science head office. Please contact our Service department to arrange this; Email: service@ionscience.com, Tel: 44 (0) 1763 208 503.
