The testing requirements for transparent jaw sample bottles usually focus on their material, sealing, physical properties, and chemical resistance to ensure that they can safely and effectively preserve samples during storage and transportation. The following are common testing requirements:
1. Material requirements
Glass material: The bottle body is required to be free of bubbles and cracks, with a smooth and transparent surface, and suitable for common chemical reagents or environmental conditions.
Testing requirements: Ensure compliance with the General Requirements for Laboratory Glassware or similar standards.
Plastic material: usually made of materials such as polypropylene (PP) or polyethylene (PE), requiring strong chemical resistance, high transparency, and no odor.
Testing requirements: Test whether the material complies with FDA or EU regulations for food contact materials to ensure non toxicity.
2. Physical performance testing
Dimensions and tolerances: The diameter of the bottle mouth, height of the bottle body, volume, etc. must meet the product design requirements and allow for a certain tolerance range.
Test requirements: Use standard measuring tools (such as calipers, measuring cups) to measure the size and volume of the bottle.
Transparency: Transparent jaw bottles require good transparency to facilitate observation of changes in the sample inside the bottle.
Testing requirements: Use a light source and photometer to test the transparency of the bottle body to ensure it meets the design requirements.
Pressure and impact resistance: The bottle body and mouth need to be able to withstand a certain amount of external pressure and impact.
Testing requirements: Conduct compression and drop tests to ensure that the bottle body does not break or deform.
3. Sealing test
Bottle mouth sealing: The bottle mouth design should be able to fit tightly with the bottle cap to prevent leakage or sample contamination.
Testing requirements: Check the sealing effect between the bottle mouth and the bottle cap through water immersion or airtightness testing to confirm that it can prevent liquid or gas leakage.
4. Chemical resistance test
Acid, alkali, solvent and other chemical substances: For chemical sample storage, sample bottles need to have a certain degree of chemical corrosion resistance.
Testing requirements: Test the tolerance of the bottle to common chemicals such as acids, bases, solvents, etc., to ensure that the bottle will not corrode or affect the sample during storage.
5. High temperature and low temperature resistance tests
Heat resistance: Transparent jaw sample bottles should be able to withstand certain high temperature environments, especially glass bottles.
Testing requirements: Conduct a high temperature test to evaluate the heat resistance of the bottle and ensure that it will not rupture at high temperatures.
Cold resistance: Bottles also need to be able to withstand certain low temperatures, especially when storing liquid or gas samples in low-temperature environments.
Test requirement: Conduct a low-temperature experiment to check the performance of the bottle in a frozen environment.
6. Health and safety testing
Harmless substance release: Especially for transparent jaw sample bottles used for food and drug storage, it is necessary to ensure that the material does not contain harmful substances.
Testing requirements: Test whether the bottle body releases harmful substances (such as heavy metals, plasticizers, etc.) to ensure compliance with relevant regulations and safety standards.
7. Impact resistance test
Drop resistance: Especially for plastic bottles, their impact resistance needs to be tested to ensure that they will not break or deform during transportation or use.
Testing requirements: Check the bottle's resistance to falling through drop tests, impact tests, etc.
8. Long term stability testing
Storage stability: The long-term storage stability of sample bottles ensures that the bottles will not change (such as aging, discoloration, etc.) due to prolonged storage of certain substances.
Test requirement: Conduct long-term simulated storage tests on the bottle to observe whether it maintains its physical and chemical properties.
9. UV resistance test
For the storage of some photosensitive materials, transparent clamp sample bottles are required to effectively block ultraviolet radiation and prevent sample damage.
Test requirement: Evaluate the bottle's UV shielding ability through UV radiation testing.
10. Labeling and Identification Requirements
Sample bottles usually require appropriate labeling on the bottle body, such as capacity, production date, material identification, etc.
Test requirements: Ensure that the label is clear, wear-resistant, and will not fall or fade due to external factors such as moisture, friction, etc.
Conclusion
The testing requirements for transparent jaw sample bottles cover multiple aspects to ensure that they meet the requirements of safety, stability, and reliability during storage and transportation. Testing standards are usually developed based on relevant industry standards, such as regulations in the chemical, food, pharmaceutical, and other industries.
