RATHBURN CHEMICALS (MANUFACTURING) LIMITED

What RATHBURN CHEMICALS (MANUFACTURING) LIMITED does

Rathburn Chemicals (Manufacturing) Limited is a family-owned UK specialty chemical manufacturer founded in 1975 by Dr Angus Campbell Mackay in the village of Walkerburn in the Scottish Borders. The company produces ultra-high-purity solvents and reagents for laboratory and industrial analytical applications, organized across four core product grades: HPLC grade (high-performance liquid chromatography), Glass Distilled (general laboratory), LC-MS grade (liquid chromatography-mass spectrometry), and PTS-DS (peptide and DNA synthesis). Impurity levels in the ultra-pure products often measure at only a few parts per million, with all manufacturing, distillation, and testing performed at the company's single Walkerburn factory to maintain full process control and traceability from raw input to finished product.

The business operates a sales-led, quote-based model with no minimum order requirements, supplying volumes from single 500ml bottles through to 1000L IBCs in UN-certified packaging. Customers include medical research institutions, pharmaceutical companies, food and beverage manufacturers, government agencies, and smaller laboratories, served across the UK via direct delivery (standard 3-5 days, overnight options for in-stock items) and internationally through European distribution partners plus agents in the Middle East and North America. The company also offers bespoke solvent formulations, ready-to-use mobile phase mixtures, and white label services. It holds ISO 9001:2015 and ISO 45001:2018 certifications, and was the first UK company to offer HPLC-grade solvents, building a five-decade reputation through customer recommendation and repeat sales rather than active marketing.

The company is privately held with no disclosed external investors, parent company, or funding rounds, and no headcount, revenue, or M&A activity is publicly reported. Management consists of the founder's legacy ownership, General Manager Roddy Stoddart, and Sales and Export Manager Sheila Anderson. The operating footprint is concentrated at the Walkerburn headquarters with international reach achieved entirely through third-party distribution relationships rather than owned overseas infrastructure.
