Technical specifications

Sample cylinders
  • Construction: Made from 304L or 316L stainless steel for corrosion resistance. 
     
  • Pressure ratings: Available in various DOT ratings, including high-pressure (up to 1800 psig) and ultra-high pressure (up to 5000 psig). TPED (Transportable Pressure Equipment Directive) compliant cylinders are also available for the EU community. 
     
  • Sizes: Range from 75 cc up to 2250 cc. 
     
  • Fittings: Standard 1/4" female NPT threads on both ends. 
     
  • Treatments: Many cylinders can be ordered with internal surface treatments like Sulfinert® or Silcosteel® for improved inertness. 
     
Accessories
  • Valves: Available in multiple configurations, including those with dip tubes and rupture discs. 
     
    • Dip tubes: Can be welded to the valve to create a headspace, which is ideal for liquefied gases to prevent over-pressurization from temperature changes. 
       
    • Rupture discs: Vent pressure to the atmosphere and must have a pressure rating lower than the cylinder's. 
       
  • Carrying handles: Available for easier and safer transport. 
     
  • Other options: Available accessories can include collars, flanges, and end caps.
