All our products are bespoke; designed and manufactured to specification. In addition, we undertake in-house research in order to develop technology platforms, specialist techniques and facilities, and to improve our processes. Platforms, such as our quadrupoles, are developed to further our understanding of specific areas of technology and can also provide building blocks for customer solutions by tailoring them to individual requirements.
