Six decades equipping the people who measure what matters.
From a single Cairo office in 1962 to a network of authorized partnerships across Egypt and the GCC LDY CO has stood beside laboratories through every era of analytical science.

Founded by Labib Demian Youssef in 1962
When Labib Demian Youssef opened LDY CO in Cairo in 1962, Egypt's analytical-instruments market was barely a few brands deep. He bet on relationships with the world's most exacting manufacturers and on a service ethic that outlasted any single sale.
Six decades later, the company is in its second generation. The roster of authorized brands has grown to nine. The Cairo office anchors a regional practice that reaches across Egypt and the GCC, with a Dubai office added in 2023.
What hasn't changed is who we serve: the scientists, engineers, and quality managers whose work depends on measurements they can trust.

Six decades of partnership
From a single Cairo office in 1962 to twelve global brand partnerships and a Dubai expansion in 2023.
Built on precision, trust, and partnership
Precision in every measurement
We supply instruments calibrated and validated for the workflows you actually run not generic spec sheets.
Local expertise, global access
Authorized partnerships with nine premium manufacturers, delivered by a team that knows your lab and your regulators.
Lifecycle support, not just a sale
Installation, training, preventive maintenance, and rapid service bundled into every instrument we deliver.
Authorized partnerships only

Trust through transparency
