BOPT BOTTLES
BOPT BOTTLES
Cylinders suitable for storage and transportation of natural gas, crude oil, formation water containing hydrogen sulphide, nitrogen, carbon dioxide, brines under pressure.

Our BOPT sample cylinders have been selected by our customers concerned about good storage of the sample. Since our titanium free piston sampling oil/gas bottles do not have any seal at the end of the sample, leaks are prevented. Furthermore, their double gasket piston avoids contamination of the hydrocarbon sample by liquid transfer pressure.
HEATING TROLLEY SBOPT HEATING TROLLEY - SBOPT
Designed to transport bottle into laboratory, the trolley keeps the sample in temperature from ambient to 175°C. Possible recombination of the sample by shaking the heating jacket.

We have developed our heating trolley for customers who needs to transport and use sampling bottles in laboratory. This trolley enables to keep the sample in a range of temperature from ambient to 175°C at constant pressure.
GASOMETER GASOMETER
A large range of gasometer for gas volume measurement at standard conditions : manual or automated, ambient or heated, vacuum to 10 bar, flow meters calibration.

Our large range of gasometers is dedicated to reply to wide needs.
VALVES

VALVES
Our different range of high pressure valves is available in manual or automatic mode. They are designed for liquids and gas and available in different materials.

VALVES

Our different range of high pressure valves is available in manual or automatic mode. They are designed for liquids and gas and available in different materials.
We have also developed our famous CVD valve, essential to decompress gas in a progressive way in order to avoid all risk related to fast decompression.
ST is also the specialist of high pressure sampling valve with VESPAC, using direct injection without any split. It enables to obtain direct composition of reservoir fluid without separation and so avoid condensation during separation.
  
RO Cells, Weighing Cells RÖ CELLS, WEIGHING CELLS
Designed for the determination of sample’s density in pressure, picnometer.
Since the determination of the density in pressure is important for fluid characterization, we have developed our Rô cell. Then, by single weighing of calibrated volume, our cells enable quick determination of sample density in pressure.
Pumps PUMPS

Pilot for Diamond Anvil PILOT FOR DIAMOND ANVIL
Designed and developed to carry out automatic handling on diamond anvil to generate gas pressure ramp or step pressure.

The incorporated micro-pump and its regulation system by differential valve enable an accuracy of 0.01bar. Furthermore, its compactness is a big advantage in laboratory.

Control Pressure System CONTROL PRESSURE SYSTEM
Specially designed to control automatically the set point pressure of Back Pressure Valve with high accuracy.

This compact system enables a constant pressure regulation system with pressure and volume display. Connected to a PC, it also enables automatic control of set point.

Pressure Amplifier PRESSURE AMPLIFIER
Dedicated to generate high pressure when medium pressure source is usually used.

Different ratios and different materials are available to manufacture our pressure amplifier. It is the solution to generate high pressure at without heavy investment.
