Sample System - Safe sampling systems for the chemical industry
Safe sample systems, sample valves and sampling systems are an essential part of any chemical processing plant. Taking samples of hazardous chemicals is one of the few moments when a plant operator comes into contact with the liquid or gas being produced or processed.
Dopak sampling systems are installed worldwide with many installations in the UK. This worldwide experience is vital in the safe sampling of chemical liquids and gases in hazardous process installations.
Derwent James Ltd is the exclusive UK agent for Dopak sampling systems and Neil Finney of Derwent James has over 15 years experience in the specification of chemical sampling systems with Dopak systems.

Better safety, fewer spills and fewer emissions
Improved safety, reduced emissions, simple maintenance and a right first time approach make Dopak sample systems the right choice when looking to improve the sampling of chemical liquids and gases on chemical, petrochemical, pharmaceutical, oil and gas processing facilities.
Your industry standard
Dopak sample systems are the industry standard for the safe, emission free sampling of liquids, gases and liquefied gases reducing spills and emissions. A Dopak closed vent sample system allows the plant operator to manually take a liquid sample (into a sealed bottle) or a gas sample (into a cylinder) with zero emissions.
Dopak closed vent sample systems are supplied specifically to the process conditions whether they are low pressure, high pressure, low temperature, high temperature, viscous liquids, inline, from reactor vessels or from pipelines – in all cases Dopak already have a solution which can be tailored for your site installation.
Typical sample system applications include;
Zero emission liquid sampling system for sampling liquids below 8 bar pressure.
Fixed volume zero emission sampling system for sampling liquids above 8 bar pressure.
Vacuum zero emission sampling system for sampling liquids using a vacuum or venturi.
Viscous liquid zero emission sampling system
Zero emission sampling valve for sampling liquids below 8 bar pressure using a pipe specification, anti static, fire safe valve.
Zero emission “in-line” sampling valve for sampling liquids below 8 bar pressure directly from pipelines.
Zero emission gas sampling system for sampling gases into cylinders.
Zero emission liquefied gas sampling system for sampling liquefied gases into cylinders.
System for the safe & emission free return of unused samples from sample bottles. Returning the fluid directly back to either the process or to a waste system.
System for the safe and emission free emptying of filled sample cylinders containing liquefied gas, ideal for use in laboratories.
Dopak also have an extensive range of sample bottles c/w caps and rubber septa. Bottles are available from 50cc to 2000cc and are available ex stock. Sample bottle materials available include standard glass, high temperature glass, amber glass, polyethylene, polypropylene, coated (unbreakable) glass and stainless steel. Septa material includes natural rubber, Teflon coated butyl rubber, Teflon coated silicone, viton, EPDM and silicone.
