The project involves the production of a simple, hand-held water testing device. The initial contract will see Sepha form, seal, and leak test 50,000 blister packs containing Aquatest's active ingredients. The company will use their innovative blister packing and leak testing machines, EZ Blister II and Blisterscan, in a newly constructed 'clean lab' at its Dundonald headquarters.  The Bill & Melinda Gates Foundation have awarded the project leaders, the University of Bristol, a $13 million grant to develop Aquatest.
