Thermo Scientific Nalgene PVC Tubing 3/8 ID x 5/8 OD x 1/8 Wall Total of 50 Feet

Thermo Scientific Nalgene Clear PVC Tubing, 3/8" ID x 5/8" OD x 1/8" Wall (8701-0140) – 50 Foot Roll

The Thermo Scientific Nalgene Premium Clear PVC Tubing (8701-0140) is a heavy-wall, high-clarity laboratory fluid transfer hose engineered for demanding liquid transport, benchtop vacuum lines, peristaltic pump assemblies, and industrial fluidics. Extruded from high-purity, non-toxic food-grade polyvinyl chloride (PVC), this tubing features a glass-clear wall that allows unobstructed visual inspection of fluid flow, phase separation, and air bubbles. The robust 1/8-inch heavy wall construction provides superior kink resistance, enhanced working pressure capability, and structural stability when subjected to vacuum or suction pressure without collapsing. Supplied as a 50-foot continuous coil, this versatile tubing provides clean, reliable performance across chemical, bioprocessing, and analytical laboratory workflows.

Technical Performance & Structural Attributes

• Heavy-Wall Kink Resistance: Thick 1/8" wall profile prevents flattening, kinking, and vacuum collapse under suction, ensuring uninterrupted fluid delivery around tight radii.
• Glass-Clear Visual Transparency: High optical clarity allows immediate monitoring of liquid movement, color changes, and particulate transport along the line.
• Smooth Mirror-Finish Inner Bore: Precision-extruded smooth interior surface reduces hydraulic drag, minimizes bio-fouling/sediment accumulation, and facilitates effective cleaning and rinsing.
• Secure Fitting Seal: Flexible Shore A durometer formulation grips tightly onto standard barbed connectors, glass stopcocks, and serrated adapters to prevent leaks under pressure.
