Production of specialized flow colorimetric dishes

Special flow colorimetric dish: detailed explanation of its purpose, characteristics, and technical parameters

1. Purpose

Flow colorimetric dishes are mainly used in conjunction with pump wash injectors, with the core application scenario being colorimetric analysis. In the fields of spectral analysis, chemical detection, biomedical experiments, etc., it can achieve real-time monitoring and quantitative analysis of sample concentration, absorbance and other parameters through continuous flow of sample solution, combined with equipment such as spectrophotometer. For example:

Concentration detection of heavy metal ions in water quality monitoring;

Biochemical index analysis of blood samples in clinical testing;

Real time monitoring of the composition of reaction liquids in chemical production processes.

2、 Characteristics

Large capacity three hole design

Compared to traditional colorimetric dishes, the three pore structure can simultaneously or alternately process multiple sample streams, significantly improving colorimetric efficiency and suitable for high-throughput analysis scenarios.

The large capacity design (with a volume of 85mm ³) reduces the need for frequent sample replacement, making it suitable for continuous flow detection and improving experimental efficiency.

Advantages of quartz material

Quartz materials have excellent optical transparency, with high transmittance in the ultraviolet visible near-infrared spectral range (especially in the ultraviolet region), avoiding interference from the absorption of light signals by the material itself.

Strong chemical stability, resistant to acid, alkali, and corrosion by most chemical reagents, suitable for the detection of complex sample systems.

Structural adaptability

Matching with a pump wash sampler, automatic sample injection and discharge can be achieved through devices such as peristaltic pumps, reducing manual operation errors and making it suitable for automated analysis systems.

3、 Detailed explanation of technical parameters

Parameter name, specific numerical meaning and function

The distance that light passes through the sample with an optical path of 10mm directly affects the absorbance measurement value, and 10mm is one of the standard optical paths for colorimetric analysis.

The spot size is 175mm. The diameter of the incident light spot in the cuvette should match the optical path and volume of the cuvette to ensure that the beam covers the sample solution and avoid light scattering or energy loss.

The sample solution volume that can be accommodated in the 85mm ³ colorimetric dish, with a large capacity design that supports long-term continuous testing or rapid switching between multiple batches of samples.

As mentioned earlier, the optical and chemical properties of quartz meet the requirements of high-precision colorimetric analysis, especially suitable for ultraviolet detection (ordinary glass has absorption in the ultraviolet region).

4、 Extended Applications and Precautions

Application extension: In addition to conventional colorimetric analysis, flow colorimetric dishes can also be used for fluorescence analysis, turbidity detection, and other scenarios. The appropriate optical path and material should be selected according to the detection principle (such as fluorescence detection can be combined with quartz material to reduce background fluorescence).

Maintenance points: After use, it is necessary to clean it promptly with distilled water or organic solvents to avoid residual contamination of the sample; Although quartz material is scratch resistant, it still needs to be handled gently to prevent collision and damage to the optical surface.
