Laboratory transparent quartz cuvette
In the field of spectral analysis, the accuracy of data begins with the sample itself and even more so with the cuvette that carries the sample. Laboratory transparent quartz cuvettes, as core consumables in ultraviolet-visible spectrophotometry, have become an inevitable choice for high-end scientific research and precise quantitative analysis due to their outstanding performance. This article will provide you with a comprehensive introduction to this product to help you make the wisest choice.
What is a quartz cuvette?
The transparent quartz cuvette is a square optical container made of high-purity fused quartz (SiO₂), mainly used for holding liquid samples to be tested and for measuring absorbance or transmittance in a spectrophotometer.
Core features and advantages:
Extremely wide spectral transmission range: This is the most notable advantage of quartz cuvettes. It has an extremely high light transmittance (usually >80%) in the ultraviolet region (as low as 190nm), the visible light region and even the near-infrared region (up to 2500nm), far exceeding that of ordinary glass or plastic cuvettes.
Outstanding thermal stability and physical properties: Quartz glass has an extremely low coefficient of thermal expansion, capable of withstanding drastic temperature changes (operating temperature up to over 1000℃, short-term use), and is less likely to crack or deform due to heat, ensuring long-term stability in measurements.
Outstanding chemical inertness: Quartz has excellent corrosion resistance to most acids, alkalis and organic solvents except hydrofluoric acid and hot phosphoric acid. It can hold a variety of corrosive reagents without being eroded, ensuring the purity of the samples and the service life of the containers.
High optical accuracy: The precise processing technology ensures accurate optical path, high window parallelism, smooth surface without defects, minimizing light scattering and reflection, and bringing extremely high accuracy and repeatability to the measurement results.
What problems can it solve?
Question 1: Ultraviolet band measurement cannot be carried out. Ordinary glass and plastic have strong absorption in the ultraviolet region and cannot be used. Quartz cuvettes have perfectly solved the measurement problems in the ultraviolet region (such as 260nm and 280nm commonly used in protein and nucleic acid analysis).
Question 2: The measurement results fluctuate greatly and have poor repeatability. Low-quality cuvettes have inaccurate optical paths and non-parallel Windows, which will introduce errors. The high-precision manufacturing of quartz cuvettes ensures the high repeatability of data.
Question 3: Vessels are prone to corrosion or cracking due to heat. In experiments involving strong acids, strong alkalis or samples that need to be heated, common materials are prone to damage. The chemical and thermal stability of quartz provides a reliable solution.
Main application fields
With its unique properties, transparent quartz cuvettes are widely used in the following fields:
1. Life science research
Nucleic acid quantitative analysis: Measure the absorbance of DNA/RNA at 260nm, and calculate the concentration and purity.
Protein research: Protein quantification is conducted through an absorbance of 280nm, or protein structure research is carried out using ultraviolet spectroscopy.
Enzyme kinetics analysis: Monitor the changes in absorbance over time at a specific wavelength and study the rate of enzymatic reactions.
2. Drug Analysis and Quality Control
Qualitative and quantitative analysis of active ingredients in drugs.
Drug dissolution test and stability study.
3. Environmental Monitoring
Water quality analysis, such as the detection of heavy metal ions, nitrates, COD (Chemical Oxygen Demand) and other indicators in water.
4. Food and Beverage Industry:
Analysis of nutritional components, detection of additive content and monitoring of food safety indicators.
5. Chemical Synthesis and Materials Science
Monitor the progress of chemical reactions.
Optical characterization of nanomaterials and polymer materials.
Customized service: Meeting your special needs
We are well aware that standard products cannot meet all complex experimental requirements. Therefore, we offer professional customization services, aiming to tailor the most suitable cuvette solution for you.
Customizable options include
Customized optical path length: In addition to the common 10mm optical path, we can provide special optical path products such as micro (such as 1mm, 2mm, 5mm) or constant (such as 20mm, 40mm, 50mm, 100mm), which are suitable for precise measurement of high-concentration or extremely low-concentration samples.
Customized volume and size: According to your sample volume and the space of the instrument sample chamber, we can customize special volume (such as ultra-micro capillary cuvettes) or external size cuvettes.
Interface and cap customization
With screw cap or insert cap: Prevents volatile solvents from evaporating, suitable for long-term kinetic determination or samples that need to be isolated from air.
With injection ports or inlet and outlet: Facilitates connection to mobile injection or online detection systems to achieve automated analysis.
Special optical design
Fluorescence cuvette: All four optical surfaces are polished and transparent, specifically designed for fluorescence spectroscopy measurement.
Cuvette with light-blocking edge: Prevents incident light from escaping from the side and enhances the signal-to-noise ratio.
Material enhancement: Ultra-high purity synthetic quartz can be provided upon request, featuring a lower fluorescence background and superior ultraviolet transmittance.
What problems can customized services solve?
The sample volume is extremely small, and the standard cuvette cannot be used for measurement. Solution: Customize ultra-micro cuvettes, and only a few microliters of sample are needed to complete the detection.
The reaction of volatile solvents needs to be monitored for a long time. Solution: Customize cuvettes with airtight screw caps to effectively prevent solvent evaporation.
The cuvette needs to be integrated into the flow analysis system. Solution: Customize cuvettes with liquid path interfaces to achieve seamless connection.
The transparent quartz cuvette in the laboratory is not merely a simple sample container; it is a key component that ensures the accuracy and reliability of spectral data. Whether it is a routine ultraviolet-visible absorption detection or a demanding scientific research application, choosing a high-quality quartz cuvette is of vital importance. We are committed to providing you with standard products of outstanding performance, and at the same time, we offer flexible customization services to address various special challenges, becoming a reliable partner for your laboratory.
