UV Quartz Flow Cuvette with Tube Two Polished Windows
The UV quartz cuvette with a polished window is a high-precision optical component designed for high-end UV-Vis spectrophotometers. Compared with standard cuvettes, its core advantage lies in the fact that the two or four optical surfaces through which the light path passes have all undergone precise polishing treatment, achieving extremely low surface roughness and extremely high smoothness. This process ensures that light passes through the sample with minimal scattering and stray light loss, thereby providing unparalleled accuracy and reliability for demanding analytical applications.
This product uses fused quartz (also known as quartz glass) as raw material. This material has extremely high light transmittance from the ultraviolet region (~185nm) to the near-infrared region (~2500nm), making it an ideal choice for ultraviolet spectral analysis. The exquisite manufacturing process combined with high-quality materials makes it an essential tool in fields such as scientific research, pharmaceuticals, and quality inspection.
What problem have we solved?
The problem of inaccurate data has been solved: The optical surface of ordinary cuvettes or ground cuvettes is uneven, which will cause significant light scattering, resulting in a higher measured absorbance value, especially in the high absorbance region, the error is more obvious. Our polishing window minimizes scattering, ensuring the authenticity and accuracy of the data.
The problem of high baseline noise has been solved: Rough surfaces can introduce stray light, causing unstable instrument baselines and increased noise, which affects the detection of low-concentration samples or weak absorption signals. The polished surface effectively reduces stray light, providing you with a smooth and stable baseline and enhancing the signal-to-noise ratio.
The problem of the instrument's performance not being fully exploited has been solved: High-end spectrophotometers themselves have extremely high optical accuracy. If low-quality cuvettes are used, they will become the "weak link" in the entire optical path system and fail to bring out the instrument's due performance. Our products are perfectly matched with high-end instruments, ensuring that every penny of instrument performance you invest in is reflected in the experimental results.
Main features and advantages
1. Ultra-high optical precision: The optical surface is polished to an extremely high degree of smoothness, effectively reducing light scattering and stray light, ensuring the absolute accuracy of absorbance measurement.
2. Wide light transmission range: Made of high-quality ultraviolet quartz material, it is suitable for a wide spectral range from 185nm to 2500nm, and is particularly good at precise measurement in the ultraviolet region.
3. Excellent chemical stability: Quartz material can withstand most acid and alkali solutions except hydrofluoric acid and hot phosphoric acid, making it convenient for the analysis of various chemical reagents.
4. Precise optical path and matching: Multiple standard optical paths (such as 10mm, 5mm, 2mm, etc.) are provided, and the cuvettes of the same batch have excellent matching, which is convenient for reference correction and reduces experimental errors.
5. Exquisite manufacturing process: Utilizing glue-free bonding technology or high-temperature melt welding process, it ensures the long-term sealing and durability of the cuvette, avoiding the risk of leakage.
Typical application fields
This high-precision cuvette is widely used in all scenarios where there are strict requirements for optical measurement accuracy
Quantitative analysis of DNA/RNA/ protein: In the fields of life sciences and biotechnology, accurately measuring the concentrations of nucleic acids and proteins is fundamental. The polishing window ensures the accurate absorbance values at key wavelengths such as 260nm and 280nm, thereby calculating reliable concentration and purity (such as the A260/A280 ratio).
Drug development and quality control: It is used for precisely determining the concentration, purity and content uniformity of active pharmaceutical ingredients, intermediates and finished products, in compliance with the strict requirements for analytical instruments in pharmacopoeias (such as USP, ChP).
Kinetic studies: Time-dependent studies such as enzyme kinetic reactions require continuous and stable monitoring of absorbance changes. The low-noise measurement environment is the key advantage of this product in such applications.
High-concentration sample analysis: For samples that need to be measured at high absorbance values (such as high-concentration dyes), reducing light scattering errors is crucial; otherwise, it will seriously deviate from Beer's law.
Environmental monitoring and food safety testing: It is used to precisely analyze the content of trace substances such as heavy metals and food additives in water, and the instruments are required to have high sensitivity and low detection limits.
Academic research and teaching: Provide reliable data support for high-level research in universities and research institutes.
Customized service
We are well aware that standard products may not meet the unique needs of all users. Therefore, we offer flexible and diverse customized services, aiming to tailor the most suitable solution for you.
What can we customize for you?
1. Special optical path: According to your requirements for sample concentration (too high or too low), non-standard optical path cuvettes can be customized, such as 0.1mm, 1mm, 20mm, 50mm or longer.
2. Special window Configuration: In addition to the standard dual-window, we can also produce three-window or four-window cuvettes for fluorescence measurement or other special optical path designs.
3. Special Materials: In addition to standard ultraviolet quartz, we can also provide special materials such as hydrofluoric acid-resistant quartz or infrared quartz.
4. Micro and ultra-micro cuvettes: For precious or rare samples, we can customize micro (such as 70μL) or ultra-micro (such as 5μL) cuvettes with extremely small sample volumes as required.
5. Special Interfaces and Shapes: According to the requirements of your instrument or experimental setup, we can customize cuvettes with flow path interfaces (for online detection), constant temperature jackets or special shapes.
Choosing a UV quartz cuvette with a polished window is not only about selecting an experimental container, but also about committing to the accuracy of data and respecting the rigor of scientific research. It can effectively solve a series of measurement errors caused by poor quality cuvettes, making your analysis results more reliable and your scientific research work twice as effective with half the effort.
