B. Braun & Lauer Confluence in dialysis

Lauer - a B. Braun company


Today the Lauer company is a wholly owned subsidiary of B. Braun. Both companies share a strong expertise in the hemodialysis field. Through years of close and careful cooperation and development, an innovative product portfolio has emerged that features a complete range of products and systems for renal care. Lauer water purification technology is among the most advanced currently available for dialysis applications, and B. Braun has been a leading provider for renal care products for more than 40 years.
