Product Selection Differences for Glass Capillary Tubes

When selecting glass capillary tubes, there are several key factors to consider:

1. Material: Glass capillary tubes are usually made from borosilicate glass or quartz. Borosilicate glass is more common and offers good resistance to thermal shock and chemical corrosion. Quartz is preferred for applications requiring higher purity and resistance to elevated temperatures.

2. Size: Consider the inner diameter, outer diameter, and length of the capillary tube based on your specific application requirements.

3. Tolerance: Check the tolerance specifications to ensure that the capillary tubes meet your precision needs.

4. Surface finish: The surface finish can vary based on the manufacturing process and can affect the flow characteristics. Choose the appropriate surface finish for your application.

5. Applications: Consider the intended use of the capillary tubes. Different applications may require specific properties such as high temperature resistance, chemical compatibility, or optical clarity.

6. Supplier reliability: Choose a reputable supplier with a track record of providing high-quality glass capillary tubes.

7. Price: Compare prices from different suppliers, but also consider the quality and specifications to ensure you are getting the best value for your needs.

By evaluating these factors, you can select the most suitable glass capillary tubes for your specific requirements.
