Plus training and installation. Additional information: The Wallingford chemistry laboratories have used Seal segmented flow analysers since the mid-1990s. Their instruments have proved very accurate and extremely reliable, with the instrument we are replacing running continually for 17 years. Adopting other analytical techniques will cause a "technology-based" change in our 25 year datasets, and this would be difficult and time consuming to "calibrate out". A new instrument would require us to develop new analytical procedures, which would be time consuming and expensive. Finally, the lab analysts are very comfortable with how these instruments operate, and are able to carry out maintenance and simple repairs without the need to call out service engineers, which saves lots of money. ## CPV classification Sealing equipment Source Contracts Finder (UK) [View official notice](https://www.contractsfinder.service.gov.uk/notice/59d65b33-e2c5-4ec6-b5cc-1e1ea4d25583) Never miss a tender like this again Get AI summaries, deadline alerts and a bid pipeline for tenders matched to your business.
