A Century of Innovation in Laboratory Sciences
Since 1924, Cargille Laboratories has been at the forefront of specialized services in the laboratory sciences. Our journey began with the development and manufacturing of optical liquids and has since expanded into a broad spectrum of laboratory disciplines, including preservatives and density standards. As we celebrate our 100th anniversary, we reflect on our rich history of leading the way in immersion oil development and standardization, contributing significantly to the microscopy field.
From our humble beginnings to becoming a leader in our industry, each step has been fueled by our dedication to delivering exceptional value and service. Our centennial is not just a celebration of our past achievements but a vibrant testament to our ongoing commitment to the future.
Join us as we commemorate a century of excellence and look forward to continuing our legacy of innovation and service in the laboratory sciences.
