Naphtha liquid samplers

To take under high pressure Petroleum Naphtha samples the conventional way is not only inefficient, but in the case of this dangerous media, humans and the environment are subjected to high safety risks, the Mechatest fix volume Naphtha samplers are the safe and efficient solution for Naphtha  sampling under high process pipeline pressure and temperature. 

The Mechatest Naphtha sampling systems are based on fix volume sampling principle, a perfect solution for liquid Petroleum Naphtha sampling from tanks, containers, pipeline and reactors, to take representative samples of Petroleum Naphtha liquids in high pressure applications. 


The first unit operation in a petroleum refinery is the crude oil distillation unit. The overhead liquid distillate from that unit is called virgin or straight-run naphtha and that distillate is the largest source of naphtha in most petroleum refineries. The naphtha is a mixture of many different hydrocarbon compounds, and it contains paraffins, naphthenes (cyclic paraffins) and aromatic hydrocarbons.


The virgin naphtha is often further distilled into two streams:

1. a virgin light naphtha with an IBP of about 30 °C and a FBP of about 145 °C containing most (but not all) of the hydrocarbons with six or fewer carbon atoms

2. a virgin heavy naphtha containing most (but not all) of the hydrocarbons with more than six carbon atoms. The heavy naphtha has an IBP of about 140 °C and a FBP of about 205 °C.  

Petroleum Naphtha sample wiki

Naphtha is a constituent of crude oil and refined fuels. It is a flammable colorless liquid that has a boiling point of 152 °C.

  • Phase; Liquid
  • Main hazards; Flammable & Toxic
  • Viscosity; +/- 0.8 cP (21 °C)
  • Vapor pressure; +/- 0.7 bar (20 °C)
  • Density; +/- 0.7 (20) g/cm3
  • Explosive limits; 1.2 – 6.9 %

Sampling of Liquid Petroleum Naphtha in Glass Bottles

The big advantage of the fix volume Naphtha sampling system is the possibility to take Petroleum Naphtha liquid sample under high process pressure and fill it into a glass sample bottle, the sample is directly take from a tank, container, pipeline, reactors or mixer. We have improved our sampling systems for liquids by:

  • Creating closed loop systems emission free which provide a safe, controlled environment
  • Suitable for high pressure process application
  • Adding sample (needle or process) purge options with Nitrogen or other gas
  • Fixed volume sampling, which minimizes both waste and costs
  • Simplifying designs, making the sampling of liquid and gas more efficient
  • Proper discharge of excess liquid or gas prevents unwanted pressure build-up in the system

These modern solutions simply regard the sampling systems themselves. Our worldwide reputation rests on the combination of excellent systems, and professional services by our team of specialists.
