Douglas Instruments Ltd

Douglas Instruments Ltd is a United Kingdom-based company that designs, manufactures and sells specialized systems for automatic protein crystallization. According to its own description, its customers are typically pharmaceutical companies, government research institutes or universities — laboratories whose scientists need to crystallize proteins for structural biology and drug-discovery work. The company is headquartered in East Garston, United Kingdom, and operates a bilingual English-language commercial website at douglas.co.uk with contact points in the United Kingdom and a US toll-free line. The company's product line is built around the Oryx family of protein crystallization robots: the Oryx8, Oryx8 LCP, Oryx4, Oryx4 LCP and OryxNano, supported by crystallization plates, accessories, upgrades, microtips and software. These instruments are marketed for sitting-drop screening, hanging-drop screening, microbatch-under-oil, lipidic cubic phase (LCP) work, microseeding, additive screening and optimization, and reservoir filling. Douglas Instruments emphasizes minimal protein consumption — for example, stating that less than 0.5 µL of protein is wasted and that only 10.0 µL is required for a 96-well screen — alongside low consumable cost and a drop range from 100 nL to 8.0 µL or larger for scaling-up. Beyond hardware, the company is associated with techniques and methods in the crystallization field, notably random Microseed Matrix Screening (rMMS), which it documents and promotes through its website, articles and webinars. Its site also provides tips and techniques, videos, research material and Oryx support resources, positioning Douglas Instruments as both an equipment vendor and a source of crystallization methodology for structural biology laboratories. Douglas Instruments is a privately held specialist supplier rather than a large diversified corporation. Its identity is defined by a narrow, technically deep focus on automating the protein crystallization workflow — from initial screening through optimization and scale-up — for research and pharmaceutical customers worldwide.

Douglas Instruments Ltd is a United Kingdom-based company that designs, manufactures and sells specialized systems for automatic protein crystallization. Its own description states that it is a UK-based company whose customers are typically pharmaceutical companies, government research institutes or universities — laboratories whose scientists want to crystallize proteins. The company is associated with East Garston in the United Kingdom, and its commercial operations are conducted through the website douglas.co.uk, which lists a UK telephone number (+44 (0) 1488 649090), a US toll-free number (1-877-225-2034), a fax number and an email address (info@douglas.co.uk). The company's public history is closely tied to the development and commercialization of automated protein crystallization instruments. Its product line centres on the Oryx family: the Oryx8, Oryx8 LCP, Oryx4, Oryx4 LCP and OryxNano robots, together with crystallization plates, accessories, upgrades, microtips and software. These systems are presented as covering sitting-drop screening, hanging-drop screening, microbatch-under-oil, lipidic cubic phase (LCP) work, microseeding, additive screening and optimization, and reservoir filling. Douglas Instruments markets the Oryx systems on the basis of minimal protein consumption — stating that less than 0.5 µL of protein is wasted and that only 10.0 µL is required for a 96-well screen — as well as low consumable cost and a drop range from 100 nL to 8.0 µL or larger for scaling-up experiments. Alongside hardware, Douglas Instruments has been active in the methodology of protein crystallization, notably random Microseed Matrix Screening (rMMS). Its website hosts documentation on preparing seed stocks and references an article by Patrick Shaw Stewart published in the SER-CAT Newsletter on rMMS. The company also provides tips and techniques, videos, research material and Oryx support resources, and it runs webinars — for example, a crystallization webinar advertised for 12 September 2025 in the UK. Douglas Instruments operates as a privately held specialist supplier rather than a large diversified corporation. Its identity is defined by a narrow, technically deep focus on automating the protein crystallization workflow — from initial screening through optimization and scale-up — for research and pharmaceutical customers worldwide. The available evidence does not specify the company's founding year, founders or ownership structure, and these details should be treated as unknown rather than assumed.
