FAQs About Benchtop Spectrophotometers
True color in chemistry is the color seen in a solution or compound in standardized conditions. It depends on electronic transitions in molecules, specifically absorption of a particular wavelength of light, and this depends on the structure of the compound.
Yes. We can supply OEM and make customized design for any specific application. Our MOQ for OEM and ODM service is 5 pcs for one model. We can not only offer standard machines, but also customized machines. Don’t hesitate to tell us your requirement, we will try our best to meet your needs.
Many people might answer "with the human eye", but this is actually not comprehensive. The human eye cannot accurately distinguish the colors of similar objects. Furthermore, everyone's perception of color varies. Therefore, people have developed color measurement tools based on the CIE color system.
Currently, there are two main types of commonly used colorimeters, as follows:
Colorimeter - It is an ideal choice for quality control (QC) on production lines, used to detect color differences.
Spectrophotometer - It is suitable for the development of color characteristics and color analysis in laboratories.
Colorimeters is a color measurement device that are used to capture, communicate, and evaluate color. Colorimeters are more affordable, portable, and easier to use, making them a suitable choice for basic color measurement applications, ideal for quick and routine tests.
spectrophotometers offer higher precision and comprehensive data analysis, are better for research, development, and when dealing with complex or highly precise requirements. The biggest difference is in capability and usage. Spectrophotometers are incredibly powerful and can offer more in-depth color measurements than a colorimeter, such as spectral data.
Colorimeters are primarily used for color quality control, while spectrophotometers are used for analysis and formulation. You can choose the appropriate color measurement equipment according to your application needs.
A spectrophotometer and colorimeter are certain instruments used by scientists to measure color by quantifying reflected or transmitted light. The results are presented in color spaces, such as L*a*b*, RGB, or XYZ. This enables the accuracy of comparison and tracking of the changes in color in chemical or material research.
