Breaking Down the Features of Nalge Nunc 870 PFA Tubing, NALGENE 8051-0375

Specifications

The Nalge Nunc 870 PFA Tubing, NALGENE 8051-0375 boasts a set of specifications that underscore its high-performance design. Its dimensions, specifically the I.D. x O.D. of 1/4 x 3/8 inches, offer a balance between flow capacity and manageable size for fitting into various setups. The wall thickness of 1/16 inch contributes significantly to its structural integrity and pressure handling capabilities.

This tubing is rated for a remarkable Max. Pressure of 248 psig at 23°C (73°F), which drops to 124 psig at 85°C (185°F). This pressure rating is crucial for applications where consistent flow control is essential, even under elevated conditions. The material, Perfluoroalkoxy alkane (PFA), is renowned for its exceptional chemical resistance across a vast spectrum of acids, bases, and solvents.

Furthermore, the Nalge Nunc 870 PFA Tubing, NALGENE 8051-0375 is specified with a Durometer hardness of Shore D, 55, indicating its semi-rigid yet durable nature. This hardness prevents collapsing under vacuum or moderate external pressure. The material also exhibits very low water absorption, ensuring that its properties remain consistent even in humid environments or when in prolonged contact with aqueous solutions.

Performance & Functionality

The core function of the Nalge Nunc 870 PFA Tubing, NALGENE 8051-0375 is to safely and reliably transport fluids, and in this regard, it excels. Its excellent chemical resistance means it can handle virtually any laboratory or industrial fluid without degradation.
