The Graham Field 722 series (Grafco/Labtron) is designed for environments where weight, portability, or cross-contamination prevention are the primary concerns. The 722B Ultralite is a permanent, featherweight stethoscope featuring a blue finish and an anodized aluminum chestpiece. The 722Y and 722Y-100 are dedicated single-patient-use (disposable) stethoscopes in high-visibility yellow. These are specifically engineered for use in isolation wards or emergency triage to prevent the spread of infectious diseases. All models in this series are latex-free and feature flexible "Y" tubing and adjustable binaurals.
