Fisherbrand NP-PVC Tubing 1/4 ID x 7/16 OD Total of 100 ft.

Fisherbrand Non-Phthalate PVC Flexible Laboratory Tubing, 1/4 in. ID x 7/16 in. OD (14-387-341) 

The Fisherbrand Non-Phthalate PVC Laboratory Tubing (14-387-341) is a flexible, glass-clear fluid transfer line engineered for general laboratory applications, liquid chromatography supply lines, peristaltic pump assemblies, and benchtop utility connections. Formulated with a specialized non-DEHP / non-phthalate plasticizer matrix, this high-purity polyvinyl chloride (PVC) tubing maintains superior flexibility and clarity while preventing chemical leachables from contaminating sensitive bio-fluids or analytical samples. With a standard 1/4 in. Inner Diameter (ID) and 7/16 in. Outer Diameter (OD), it provides a snug, leak-resistant friction fit over standard barbed fittings, glass connectors, and manifold adapters. Supplied as two 50 ft. coils, this versatile tubing lot delivers broad chemical resistance against inorganic acids, alkalis, and aqueous salt solutions.

Technical Performance & Structural Attributes

• Non-Phthalate / DEHP-Free Formulation: Environmentally conscious bio-compatible formulation eliminates traditional ortho-phthalate plasticizers, preventing sample contamination and regulatory compliance issues.
• Glass-Clear Optical Transparency: Exceptional visual clarity allows real-time observation of fluid flow, gas bubbles, suspended particulates, and fluid interface boundaries.
• Smooth Inner Bore Geometry: Mirror-smooth interior wall reduces fluid friction, prevents particulate buildup, and simplifies post-use flushing and sanitation.
• Kink-Resistant Flexibility: Soft Shore A durometer provides tight bend radius characteristics without collapsing or restricting fluid throughput.
