Sampling Products > IsoTube®
The original IsoTube gas sampling system was developed in response to sampling and shipping difficulties we and our customers experienced. Over 1 million IsoTubes have been sold and used by hundreds of customers around the globe. Now, 20 years later, the next-generation IsoTube and IsoSampler™ line continue to set the industry standard for mudgas sampling and other gas sampling applications.
| IsoTubes offer many advantages over competitors: |
| • |
More analysis potential: IsoTubes are evacuated to minimize air contamination, and IsoSampler devices are designed to pressurize the collected samples. More gas at higher concentrations allows the laboratory to generate more data points and improve precision for our customers. |
| • |
Faster, more precise sampling: Evacuated IsoTubes sample quickly, maximizing data precision at each depth. Data from legacy flow-through systems represents an average gas composition over a wider range of depth in the well, especially when modern field equipment with lower gas flow rates is used. |
| • |
Preserves sample integrity: Each IsoTube is pressure- and vacuum-tested to ensure sample integrity. Long-term testing shows virtually no chemical or isotopic degradation of gases stored for 3 years or longer. |
| • |
Environmentally-friendly: IsoTubes are 99.9% recyclable. |

IsoTube Equipment
IsoSampler Pro™
IsoTubes are primarily designed for sampling during mudgas logging. The simple snap-in feature of the IsoSampler Pro allow samples to be taken instantaneously from a flow stream by simply snapping an IsoTube into the sampling chuck. This can all be done without interfering with the operation of other mud-logging equipment.

IsoSampler Go™
IsoTubes can also be used as an alternative to expensive cylinders. Source pressure up to 3000 psig can be sampled with the IsoSampler Go, which will reduce the pressure to approximately~50 psig in the IsoTube.
