Optical properties are a crucial aspect of Collection Tube design, providing necessary information for experimentalists to observe and analyze samples.
Transparency:
The body of Collection Tube is usually made of transparent material, such as polypropylene or polyethylene. Transparency is the basis of optical properties and allows the experimenter to clearly see the sample inside the tube. The transparent tube helps to observe the color, turbidity, sediment and other characteristics of the sample, providing an intuitive basis for the interpretation of experimental results.
Optical transmittance:
The material of Collection Tube should have good optical transmittance, that is, the degree of transmission of visible light. This ensures that light can pass through the tube during experiments or detection, allowing the structure and features inside the sample to be accurately observed. Materials with high transmittance help improve the accuracy and reliability of experiments.
UV transmittance:
Some experiments may require the use of ultraviolet light (UV) for sample analysis, so the tube material of the Collection Tube needs to have good UV transmittance. This is important for analyzing biomolecules such as DNA and proteins because they have specific absorption and fluorescence properties under UV light.
Impact of optical changes:
Collection Tube must not cause optical changes during experimentation or storage. This includes avoiding scattering, absorption or reflection of light by the tube material. The optical stability ensures the consistency of experimental results and avoids errors that may be caused by the tube material.
Anti-UV absorption:
In order to protect certain biological samples or experimental substances, the tube body of the Collection Tube may need to have anti-UV absorption properties. This helps prevent UV damage to samples, especially during prolonged storage.
Thermal stability:
In some experiments, the Collection Tube may be affected by temperature, so the tube material should have good thermal stability to prevent changes in optical properties caused by temperature changes. This is particularly important, for example during centrifugation, where the tube may be subject to high centrifugal forces and temperatures.
