Safe containment and transport of gases and liquids in volumes from 10ml to 20 litres is assured by Hoke Sampling Cylinders, now produced as both single- and double-ended units, with pressure rating up to 5000 psi. Available to HSE, TUV, USA Department of Transport and Transport Canada approvals, they are designed and manufactured to stringent specifications providing long performance life and maximum user safety. Fabrication is seamless on all sizes over 30cc, with 304L and 316L stainless steel as standard and optional Monel, nickel and Inconel. Special coatings such as FEP and Silcosteel are available for chemical compatibility. Cylinders can be supplied complete with valves, carrying handles, end caps and outage tubes. Increased wall thickness in the threaded area prevents expansion when valves are installed, and completely formed ends maximise strength while eliminating potential leak paths.
