Aluminum hub needles are used for large animal applications requiring a durable needle. The tri-beveled, anti-coring tips are computer-ground for consistent sharpness. The needle has an anti-friction coating for minimal penetration resistance and animal discomfort. They come in tamper-evident cartridges which are safe, convenient, easily disposed of, transportable and are color-coded to follow ISO standards. The lot number is printed on each cartridge for easy tracking.
