Product description
PFA test tube for trace analysis sample management, acid / alkali reactions, ICP-MS sample prep, and low-background contamination sample storage.
Why choose a PFA test tube
PFA test tubes are used in lab workflows that require strict control of container cleanliness, chemical compatibility, and sample residue. Compared with standard plastic tubes, PFA is commonly chosen for high-cleanliness sample storage, acidic sample preparation, and trace-element analysis. The smooth inner wall helps reduce sample adhesion and residue risk.
主要特色
High-cleanliness PFA material
Suitable for sample-handling workflows sensitive to container-borne background contamination, including semiconductor, chemical analysis, and trace-metals analysis.
Smooth inner wall reduces residue risk
The smooth inner wall helps reduce sample adhesion and liquid residue, suiting small-volume dispensing, storage, and sample preparation.
Compatible with PTFE sealing stoppers
PTFE sealing stoppers can be paired on request for sample storage, short-distance transfer, and lab-workflow management.
Standard 15 mL / 20 mL sizes
Available in 15 mL and 20 mL sizes, both with 16 mm outer diameter — pick based on sample volume and workflow.
How to choose a PFA test-tube specification
- • 15 mL: suits small samples, standards, intermediate sample-prep liquids, and short-term storage.
- • 20 mL: for workflows that need slightly higher capacity, longer tube height, or larger sample volume.
- • For sealed storage: consider pairing with a PTFE sealing stopper.
- • For trace analysis: pair with the lab's existing acid-wash, blank verification, and clean-storage procedures.
- • For strong acids or specialty chemicals: confirm suitability against the acid system, temperature, and contact time.
FAQ
What applications does the PFA test tube suit?
PFA test tubes suit high-cleanliness sample storage, small-volume dispensing, acidic sample preparation, and trace-metals analysis workflows. Common uses include sample prep for ICP-MS, ICP-OES, and AAS, plus sample management in semiconductor, chemical, and materials labs.
Can a PFA test tube be paired with a sealing stopper?
Yes — a PTFE sealing stopper can be paired on request. The exact pairing is confirmed against tube size, sample type, and storage conditions.
How does PFA differ from standard PP / PE test tubes?
PFA is used in workflows that demand higher cleanliness, chemical compatibility, and trace-analysis sensitivity. Compared with standard PP or PE tubes, PFA suits acidic samples, high-cleanliness samples, and analytical scenarios sensitive to background contamination.
Can PFA test tubes be used for ICP-MS sample preparation?
Yes — PFA test tubes can be used in related sample storage, dispensing, and preparation workflows. For ICP-MS or trace-metals analysis we still recommend pairing with your existing cleaning, acid-wash, and blank-verification procedures.
What sizes are currently available?
Available in 15 mL and 20 mL — both with 16 mm outer diameter and heights of 125 mm and 150 mm respectively.
How do we confirm fit for our sample?
Please share sample type, acid system, operating temperature, storage time, whether sealing is needed, and the analytical method (e.g. ICP-MS, ICP-OES, or other) so we can confirm a suitable specification.
Need to confirm whether a PFA test tube fits your sample workflow?
Share sample type, acid system, volume needs, whether a PTFE sealing stopper is required, operating temperature, and analytical method, and we will help confirm a suitable specification.
