Frozen-state morphology and ultrastructure
plunge or high-pressure freezing
Material Analysis · Microscopy & Imaging
Characterise frozen-state morphology and ultrastructure, interfaces, pores, particles, and fracture faces, and optional elemental or tomographic information using a scope agreed around your sample and decision.
Why this test
Cryogenic TEM with Cryo-FIB Preparation is selected when the project needs defensible information on frozen-state morphology and ultrastructure, interfaces, pores, particles, and fracture faces, or optional elemental…

Choose the scope
The measurement mode, preparation route and reporting depth depend on what you need to learn from the sample.
frozen-state morphology and ultrastructure

optional elemental or tomographic information
Common outputs
Fields, measurement conditions, processing and file formats are confirmed before work begins.
Cryo-SEM or cryo-TEM micrographs reported with the agreed units, sample reference and measurement conditions.
Annotated structures at agreed scales supplied in a labelled format suitable for direct sample or condition comparison.
Optional cryo-EDS, tomography, or lamella record provided with the processing basis and quality checks agreed during technical review.
Method-specific images included when selected in the confirmed reporting scope.
Sample requirements
Provide representative, clearly labelled samples and identify the region, feature or comparison that matters.
| Suitable sample or input | Submission requirement | Planning note |
|---|---|---|
| Powder / particles | Provide a dry, homogeneous and clearly labelled sample in a sealed container. | Exact mass and any drying or dispersion step are confirmed after technical review. |
| Liquid / solution | Provide a sealed, compatible container labelled with composition, concentration and solvent. | Declare volatility, corrosivity, suspended solids and any storage or temperature requirement. |
| 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. |
Region of interest: include a marked image, sketch or reference when the target feature is localised.
Handling: declare hazardous, magnetic, volatile, moisture-sensitive, beam-sensitive or temperature-controlled material before dispatch.
Questions and answers
Short answers to issues that can change preparation, scope or interpretation.
Provide powder / particles, liquid / solution, biological / soft material, test coupon / specimen as applicable. Exact quantity, dimensions and preparation are confirmed during technical review.
Choose the mode around the decision you need to make. For frozen-state morphology and ultrastructure, start with plunge or high-pressure freezing; add cryo-fracture and sublimation when comparison or quantification is required.
Typical turnaround is 10 working days after sample acceptance and method confirmation.
Ice contamination, devitrification, and beam damage can obscure fine structure. International shipment of frozen or hazardous samples requires case-by-case approval.
