Proserv sample cylinders are designed for the safe reliable containment, transportation and storage of pressurised oilfield samples.

Our cylinders are supplied with transportation boxes for shipment, complete with European (PED and TPED), United States (DOT), Canadian (TC) and Australian Standards (AS) certification where applicable.

Proserv produces standard products using specialist materials that are NACE MR-0175 approved for use in severe service environments. We work with different elastomer manufacturers to identify appropriate sealing solutions for different environments such as high pressure, high temperature and high H2S.

Proserv works with several different vendors to provide non-reactive coatings. Coatings can be applied to our tools and cylinders to reduce any losses of H2S or Hg until accurate analysis can be performed.
