## Summary

The Health and Safety Executive (HSE), a central public authority in the United Kingdom, has initiated a procurement process for the supply of a Gamma Densitometer, essential for conducting large-scale liquid hydrogen experiments at the HSE Science & Research Centre in Buxton. This procurement falls under the goods category and is managed by an open competition method. The procurement process is at the tender stage, with a tender submission deadline set for 20th August 2025, at 13:00 BST. The related enquiry period will conclude on 6th August 2025, at 13:00 BST. The total estimated contract value is £36,000. The procurement is particularly suitable for small and medium-sized enterprises (SMEs), with the contract starting on 3rd November 2025.

This tender presents an excellent opportunity for businesses specialising in scientific instrumentation, particularly those manufacturing or supplying densitometers. Companies with the capability to meet precise specifications and tight delivery deadlines are well-suited to compete, given the critical nature of the equipment to ongoing safety assessments in liquid hydrogen research. SMEs with a competitive pricing structure and robust supply chain capabilities may find this contract particularly advantageous for expanding their presence in the public sector scientific equipment market.

## Notice

HSE Science & Research Centre (Buxton) has been conducting large-scale liquid hydrogen experiments to assess the hazards around the use of liquid hydrogen. To make accurate flow measurements for safety assessment, HSE requires a gamma densitometer to measure the density of the liquid hydrogen flow. The densitometer will be attached to a vacuum insulated liquid hydrogen release rig.
