Lab Unlimited UK
The Carl Stuart Group was founded in 1984 by Stuart and Gillian Smith. From a small beginning our business has grown to encompass many services and products, covering different market sectors and geographical regions. The focus of our business, however, remains the same. We are a customer orientated company and strive to meet and exceed your expectations in everything we do.
As our portfolio grew we decided to present and promote our product and technical service offerings under distinct brands. The Laboratory instrumentation, consumables and technical & integration services are promoted under Lab Unlimited.
The Lab Unlimited product portfolio offers laboratory/analytical products from more than four hundred leading manufacturers. A substantial part of this offering is published on this very site. We also produce a printed catalogue that can be requested by emailing us.
