## Summary

Cardiff University has completed a procurement process for the acquisition of the Zetaview Evolution twin NTA system, with the contract awarded to Analytik Ltd. This tender was initiated under the direct procurement method, specifically designated as a below-threshold acquisition without competition, due to the uniqueness of the system, particularly its patented ability to measure zeta potential—an essential requirement for Cardiff University's School of Physics. The contract was signed on 3rd December 2025, and the period of delivery will commence on 1st January 2026 and end on 1st January 2027. The system is classified under goods and falls within the analysers sector, with delivery set to Cardiff, United Kingdom (region UKL22).

This procurement presents significant opportunities for businesses in the scientific instrumentation and biomedical equipment sectors, particularly those looking to supply innovative and specialised measurement systems. Companies with capabilities in nanoparticle tracking analysis and advanced scientific innovations could find similar tenders beneficial, especially when requirements include patented technology like the flow cell aspect of the equipment purchased by Cardiff University. Given the single-source, direct procurement route due to specific technical criteria, only those businesses offering highly specialised and unique solutions will effectively compete in similar tenders.

## Notice

The School of Physics require the capability to measure the particle size, concentration, zeta potential and fluorescence by nanoparticle tracking analysis (NTA, NOT dynamic light scattering - DLS). The Particle Metrix system is currently the only one that offers this. The only other NTA system available is from Malvern Panalytical, however this doesn't measure zeta potential. The concentration scanning technique of the Zetaview is filed for patent but critically, the School requires zeta potential and this is the only one on the market. The flow cell aspect of this equipment is also patented, further strengthening the need to purchase this equipment from Analytik.
