M9100 Automatic Core Flow Tester
![]()
The Grace Instrument M9100 Automatic Core Flow Tester is designed to accurately measure permeability changes to a formation core sample in a high temperature and high pressure environment, while exposing it to a variety of test fluids. A core that is collected from a formation is inserted into a core holder. A computer with Grace Instrument M9100 Core Flow™ software controls the environment within the core holder and the injection rate and/or pressure of fluid into the core. Many different types of tests can be performed with the M9100 by changing the test parameters in the test setup section of the M9100 Core Flow™ software.
The M9100 is easy to operate:
| Step 1: | Set up test parameters using the M9100 Core Flow™ software |
| Step 2: | Insert a core into the core holder |
| Step 3: | Load test fluid into the accumulator |
| Step 4: | Click Start in M9100 Core Flow™ on the PC |
M9100 Core Flow™ software:

- Standard core injection with optional cross-face
- Tests controlled and data recorded by computer
- Test data is exported as .csv files into any spreadsheet program
M9100 can also be built to custom specifications.
