This selection represents specialized Graham Field (Grafco) disposable tourniquets designed for high-volume clinical environments. These adult-sized bands feature an 18-inch length for easy tying and consistent compression during venipuncture. The 4109-1 model is made of high-quality smooth latex in white, while the 4109-1LF is a latex-free alternative in blue to eliminate allergic risks for sensitive patients. Both versions are designed for single-use to prevent cross-contamination and are bulk-packaged in 250-count boxes for maximum efficiency.
