Resilient next-generation tubing retains its shape and flexibility even after folding tightly into a pocket. It provides longer stethoscope life due to improved resistance to skin oils and alcohol, and is less likely to pick up stains. Next-generation tubing is not made with natural rubber latex, a benefit to sensitive clinicians and their patients. And, to play its part in the protection of human health and the environment, the next-generation tubing is not made with phthalate plasticizers.
