Whether you work in a biopharmaceutical facility, government research site, diagnostic labs or academic research group, we have solutions to support your work. We’re proud that our customers cover a broad swath of science and hail from across the world. Learn about our key portfolios:

• Chemistry — Chemists depend on our expansive catalog of chemicals, solvents and materials. We always look for novel ways to accelerate research and improve life in the lab, including new technology and digital solutions.  
• Biology — Every lab keeps a list of tools and consumables they rely on every day. When the supply cabinet runs out, research grinds to a halt. We provide a wide array of reliable tools — from PCR kits to filters — and a lengthy list of others — to biologists tackling new or long-standing questions.
• Diagnostics and Regulated Materials — We ensure customers can access critical materials, like lateral flow membranes, reagents and peptides, to run tests and advance their research.  
• Biomonitoring — A sterile environment is paramount for many processes, and we provide instruments and testing kits to ensure this. We also provide all the tools researchers need to create successful cultures. 
• Lab Water — The most well-thought-out research experiments are compromised if water is riddled with trace contaminants. Researchers across disciplines have put their trust in our lab water systems, consumables and service for over 50 years.
