Product Selection Differences for Glass Capillary Tubing

When selecting glass capillary tubing, there are several key differences to consider:

1. Material Composition: Glass capillary tubing can be made from different types of glass like borosilicate, soda-lime, or quartz. Each type has its own properties in terms of thermal resistance, chemical compatibility, and transparency.

2. Dimensions: Consider the inner and outer diameters, as well as the length of the capillary tubing. These dimensions will affect the flow rate, sample volume, and pressure resistance of the tubing.

3. Surface Coating: Some glass capillary tubes are coated with materials like polyimide or silica to improve flexibility, prevent sample adsorption, or enhance biocompatibility.

4. Application: The intended use of the capillary tubing is crucial. Different applications, such as chromatography, microfluidics, or medical diagnostics, will have specific requirements in terms of chemical resistance, temperature stability, and flow control.

5. Manufacturing Quality: Ensure that the glass capillary tubing is manufactured to high standards to guarantee accuracy and consistency in performance.

6. Supplier Reputation: Choose a reputable supplier that offers quality products, technical support, and customization options to meet your specific needs.

Considering these factors can help you select the most suitable glass capillary tubing for your application.
