NALGENE® 8030 280 PUR Tubing, ester-grade

Clear, flexible, clean polyurethane tubing with excellent chemical resistance. High-purity lab tubing that will stand up to very demanding applications. Clear and almost as flexible as conventional laboratory tubing with formulations based on polyvinyl chloride. Extraction of plasticizers or other volatile additives from these PVC formulations may cause hardening of the tubing or contamination of samples. PUR tubing is pure polyurethane; it contains no plasticizers and low levels of extractables, so it’s ideal for high-purity work. Compared with PVC tubing, PUR tubing also has superior chemical resistance to fuels, oils and some solvents. Excellent tensile strength and toughness make PUR suitable for pressure applications. Because of its outstanding physical properties, PUR tubing of a given wall thickness will perform as well as PVC tubing with much thicker walls. Of the two PUR grades, 280 offers better resistance to weak organic acids and oils, with somewhat higher working pressures.
