VICI Valco’snew nickel-clad tubing is available with fused silica (FS) tubing, PEEK® tubing, and polyimide-coated fused silica tubing. These selections make the nickel-clad tubing ideal for HPLC and UHPLC use.
The fused silica tubing has a thick nickel coating applied to achieve a higher pressure rating. A thin nickel coating may also be used for resistive heating for fused silica tubing. The nickel also performs as a temperature sensor. The result is the lowest thermal mass FS column currently available. Nickel clad FS also allows the use of metal ferrules for improved leak-tight connections.
The nickel-clad FS tubing permits resistive heating of columns and transfer lines. It offers superior heat transfer to FS over wire-heating methods. The clad PEEK tubing allows direct connections using metal ferrules to produce enhanced pressure performance.
Nickel-clad PEEK tubing comes in 1/32” OD (IDs of .002 to .015) and 1/16” OD (IDs of .002, to .040) permitting use of PEEK tubing up to 40,000 psi.
