Product description
PFA crucible for sample digestion with HF, strong acids, and strong alkalis, and for low-background-contamination trace-analysis sample prep.
Why choose a PFA crucible
PFA crucibles are used in sample-prep workflows that need strict control of container cleanliness, chemical compatibility, and sample background contamination. Compared with standard glass or plastic vessels, PFA is the better fit for some acidic samples, high-cleanliness chemicals, and trace-metals analysis applications. The flat base suits hotplate use for sample heating, evaporation, concentration, acid treatment, and lab sample prep. A PFA or PTFE lid can be paired on request to reduce external contamination or sample exposure.
主要特色
High-purity PFA material
Suited to semiconductor, high-cleanliness lab, and trace-analysis sample-prep workflows. Helps reduce background contamination from generic container materials.
Flat base for hotplate use
The flat bottom suits hotplate-based sample heating, evaporation-to-dryness, and concentration; actual heating conditions are confirmed against the method.
Compatible with PFA or PTFE lids
PFA or PTFE lids can be paired per sample-handling needs to reduce sample exposure, lower external-contamination risk, or aid workflow management.
Suited to trace-analysis sample prep
Suitable for sample prep across ICP-MS, ICP-OES, AAS, etc. — especially for samples sensitive to container background contamination.
Multiple volume options
Available in 20, 30, 50, 100, 250, and 500 mL — choose based on sample volume, evaporation volume, and workflow.
How to quickly confirm a suitable specification
To help confirm the right PFA crucible volume, lid, and use conditions, please share the following:
- • Required volume or sample volume
- • Sample type and acid system
- • Whether hotplate heating is needed
- • Operating temperature and heating time
- • Whether evaporation, concentration, or acid treatment is needed
- • Whether a PFA or PTFE lid is needed
- • Whether for semiconductor, high-cleanliness, or trace-analysis workflows
- • Analytical method, e.g. ICP-MS, ICP-OES, AAS
- • Estimated quantity and delivery timing
How to choose a PFA crucible volume
- • 20 / 30 mL: suits small samples, method development, micro-scale sample prep, and small-volume evaporation.
- • 50 / 100 mL: suits general lab sample heating, acid treatment, concentration, and sample-prep workflows.
- • 250 mL: suits larger sample volumes, batch sample prep, or workflows that need a wider opening.
- • 500 mL: suits larger sample volumes, larger-volume concentration, or process-end sample prep.
- • For trace-analysis use: pair with the lab's existing acid-wash, blank-verification, and clean-storage procedures.
- • For hotplate use: confirm heating temperature, heating time, acid system, and safety conditions.
FAQ
What applications does the PFA crucible suit?
PFA crucibles suit high-cleanliness sample prep, hotplate-based evaporation-to-dryness, sample concentration, acid treatment, and trace-metals analysis workflows. Actual suitability is confirmed against sample type, acid system, temperature, and heating time.
Can a PFA crucible be used on a hotplate?
Yes — the PFA crucible has a flat base suited to hotplate-based sample heating, evaporation-to-dryness, or concentration workflows. Actual temperature and duration are confirmed against sample and method.
Can a PFA crucible be heated with an open flame?
Open-flame heating of the PFA crucible is not recommended. For heating, pair the crucible with a hotplate or another suitable lab heating device per product specifications, and confirm temperature and safety conditions.
Can a PFA crucible be paired with a lid?
Yes — PFA or PTFE lids can be paired on request. The actual lid configuration is confirmed against volume, sample type, heating conditions, and intended use.
How does a PFA crucible differ from a glass crucible?
PFA is used in sample-prep workflows that need chemical compatibility, high cleanliness, and low background-contamination risk. Compared with glass vessels, PFA crucibles fit some acidic-sample and trace-analysis applications better — but the final choice depends on chemical, temperature, and analytical goal.
Is a PFA crucible suitable for ICP-MS sample prep?
Yes — PFA crucibles can be used in sample prep for ICP-MS, ICP-OES, AAS, and similar. For trace-metals analysis, pair with the lab's existing acid-wash, cleaning, blank-verification, and clean-storage procedures.
What volumes are currently available?
Available in 20, 30, 50, 100, 250, and 500 mL. Body diameter and total height per volume are in the spec table.
Need to confirm PFA crucible volume, lid, or heating configuration?
Share required volume, sample type, acid system, heating temperature, whether a PFA / PTFE lid is needed, and analytical method, and we will help confirm a suitable specification.
