Perkin Elmer Valves Include Nuts And Ferrules, But Not Loops - PE (Additional S&H or Hazmat Fees May Apply)

Perkin Elmer A majority of the Arnel™ configurations utilize two different types of valves. Most can be categorized as external volume injectors while the other type is an internal sample injector. The injection volume of an internal sample injector valve is determined by the size of etching on the rotor of the valve. External volume sample size is determined by a sample loop outside the valve. External valves are used primarily for sample injection and/ or switching applications. A valve used for just switching requires another valve for sample injection. - PE (Additional S&H or Hazmat Fees May Apply)
