Why this service
What Seebeck can help you understand
Thermoelectric transport testing applies a controlled temperature gradient to determine Seebeck voltage and measures electrical resistance under defined geometry. Together with thermal conductivity,…

Common outputs
A result package matched to the decision you need to make
Fields, conditions, processing and file formats are confirmed before work begins.
Seebeck coefficient reported with the agreed units, sample reference and measurement conditions.
Electrical resistivity or conductivity supplied in a labelled format suitable for direct sample or condition comparison.
Power factor where both are measured provided with the processing basis and quality checks agreed during technical review.
Temperature-dependent transport plots included when selected in the confirmed reporting scope.
Sample requirements
What to provide before work begins
Provide representative, clearly labelled samples and identify the decision, feature or comparison that matters.
| Suitable sample | Submission requirement | Planning note |
|---|---|---|
| Biological / soft material | Provide fixed, preserved or otherwise stabilised material in the agreed container and medium. | Declare biological hazards and confirm fixation, dehydration, temperature and disposal requirements. |
| Test coupon / specimen | Provide labelled specimens prepared to the agreed geometry, orientation and surface condition. | Confirm the applicable standard, dimensions, loading direction and number of replicates. |
| Device / assembly | Provide a complete labelled device or assembly with drawings, interfaces and operating limits. | Confirm power, connections, operating state, access restrictions and permitted disassembly. |
Objective: state the decision, comparison or acceptance criterion the work must support.
Handling and access: declare hazards, instability, confidentiality, file constraints or special logistics before dispatch or transfer.
Questions and answers
Common planning decisions
Short answers to issues that can change preparation, scope, timing or interpretation.
Is the listed starting price for a full temperature sweep?
No. It is per sample per temperature point; multi-point programmes are priced from the selected range and count.
What is the typical turnaround?
Typical turnaround is 5 working days after sample acceptance and method confirmation.
