The tube for the aerosol particle counter allows to connect the isokinetic sampler (probe) with the counter.

Hytrel-lined PVC tubing is designed to offer the flexibility and durability of PVC tubing with a liner of inert Hytrel, made by DuPont, for additional resistance to oils, high temperatures and gas permeability. A patented process molecularly bonds liner and cover to make a virtually inseparable product. This cost-saving co-extrusion permits Hytrel-lined PVC to be substituted for all-Hytrel tubing in many applications. The Hytrel polyester liner offers internal resistance to chemical attack, abrasion and contamination, along with a high degree of resistivity to the adherence of particulates, making Hytrel-lined PVC exceptionally suited for use in air sampling applications. Hytrel-lined PVC tubing’s black PVC cover offers excellent resistance to abrasion and oils, as well as ultraviolet exposure. The pliable PVC also provides a degree of shock resistance and insulates the tubing from electronic interference. Hytrel-lined PVC tubing is made of FDA-sanctioned ingredients for use with food contact surfaces. The tubing is certified for CFR Title 21 Section 177.1550 and CFR Title 21 Section 177.2600. It may be subjected to ethylene oxide sterilization processes.
