It is considered that this contract can be awarded using the negotiated procedure without prior publication of a contract notice pursuant to regulation 32(2)(b)(ii) of the Public Contracts Regulations 2015 for technical reasons. While the Tenax-ta tubes can be sourced from multiple manufacturers the tubes themselves are unique to each suppliers' specifications and will not be compatible with machines designed for specific suppliers test tubes. MOD only requires tubes and immediately associated items, which are required to be compatible with its existing machines. Switching suppliers would require recertification of the laboratories testing processes for the samples as well as the purchase of new equipment. Using incompatible equipment would result in anomalies with unacceptable risk to the safety of MOD personnel. ## CPV classification Test tubes Source Contracts Finder (UK) [View official notice](https://www.contractsfinder.service.gov.uk/notice/cd2a256b-f4ef-44aa-b5f6-35d79d5e322e) Never miss a tender like this again Get AI summaries, deadline alerts and a bid pipeline for tenders matched to your business.
