GBL Gül Biyoloji Laboratuvarı

GBL Gül Biyoloji Laboratuvarı is a Turkey-based healthcare manufacturer focused on in vitro diagnostic products, medical device disinfectants, biocidal products, microscopy reagents, and related laboratory consumables. Founded in 1990 by Dr. Sait Hulusi Özbudun, the company began producing laboratory diagnostic kits in the mid-1990s and medical device disinfectants and biocidal products in 1998. Its commercial portfolio includes hemodialysis machine disinfectants, endoscope and surgical instrument high-level disinfectants, skin and hand disinfectants, microscopy stains, staining sets, chemical reagents, and other laboratory products. GBL operates certified manufacturing under ISO 9001 and ISO 13485 and markets products in Turkey while exporting to multiple international regions. The business appears to be a long-standing private manufacturer rather than a therapeutics developer, with revenue generated from marketed products and laboratory-related services.
