1.5ml Extration Tube with Filter

1. Features Summary

1. Materials and Structure

• Primary Materials: The extraction tubes are typically made from plastic materials such as PE (Polyethylene) and PP (Polypropylene), which offer good chemical stability and resistance to corrosion.
• Structural Design: The product comes in various forms, including double-cap extraction tubes and double-ear droppers, catering to different usage requirements.

2. Sealing Performance

• Pressure Seal Test: Some extraction tubes undergo a pressure seal test at -40kPa for 10 minutes to ensure tight sealing and prevent leaks or cap bursts.
• Screw Cap Design: For example, the PP screw-cap extraction tube uses a screw cap structure, which enhances the sealing performance and reduces the risk of liquid leakage.

3. Functionality

• Sterile Operation: Some extraction tubes are designed to be sterile, meeting the needs of experiments requiring a sterile environment, such as biological and chemical analysis.
• With Filter: Some models, such as the PE tube with PS filter-tipped droppers, are equipped with filters that effectively prevent aerosol generation, ensuring safety during use.
• Suitable for Various Liquids: These tubes are compatible with a wide range of liquids, whether they are ordinary liquids, viscous liquids, or impure liquids, making them suitable for extraction and titration tasks.

4. Accuracy and Capacity

• Minimal Error: The droppers are made from high-quality materials, ensuring minimal error and high precision, which guarantees the accuracy of experimental results.
• Variety of Capacities: Available in various capacity sizes (e.g., 1.5ml, 1.8ml, 2ml, 3ml, etc.), the tubes can meet different experimental needs.

5. Ease of Use

• High Flexibility and Toughness: The PE material provides flexibility and toughness, making it easy to squeeze and control the solution flow.
• Transparent Droppers: The droppers are typically made of transparent PS or semi-transparent PP materials, making it easy to observe the remaining liquid and enhancing operational convenience.

2. Conclusion

The design of the extraction tubes focuses on sealing performance, accuracy, and ease of use, making them ideal for precise experiments and applications that require a sterile environment. They also offer good compatibility, allowing them to handle various types of liquids, ensuring the reliability and accuracy of experimental results.
