Quartz cuvette-quartz flow cell

Quartz cuvettes and quartz flow cells are the core optical containers in spectroscopic analysis instruments, designed specifically to hold liquid samples under test. We use high-purity fused silica material (SiO ₂ content ≥ 99%), manufactured by precision optical processing technology, to ensure that the product has high transmittance and chemical stability in the ultraviolet, visible and near-infrared bands. Whether it's standard testing or special customization, we can provide precise and reliable optical solutions for global customers.

FAQ

What is the essential difference between quartz colorimetric dishes and ordinary glass colorimetric dishes?

Ordinary optical glass has strong absorption in the ultraviolet region below 340nm and cannot be used for UV quantitative analysis of substances such as nucleic acids and proteins. Our high-purity quartz colorimetric dish has extremely high transmittance (usually better than 80%) in the wide wavelength range of 190nm to 2500nm, and has strong acid and alkali corrosion resistance and high temperature resistance, making it the first choice for high-precision spectral analysis.

What specifications of customized services can you provide?

We can provide comprehensive customization according to the specific experimental needs of our clients. Including optical path length (from ultra short 0.1mm to long optical path 100mm or even longer), sample chamber volume (such as micro/ultra micro colorimetric dishes that only require a few tens of microliters), window materials, and special structures (such as fluorescent colorimetric dishes with constant temperature jacket, sealing cover, or four sided polishing).

What scenarios are quartz flow tanks suitable for?

The quartz flow cell has an inlet and outlet, which is very suitable for connecting peristaltic pumps or automatic injection systems. It is widely used in drug dissolution testing, online water quality monitoring, chemical reaction kinetics research, and high-performance liquid chromatography (HPLC) combined detection, which can achieve real-time spectral analysis of continuously flowing samples.

Core value: Solve experimental challenges for you

Our quartz cuvettes and flow cells are dedicated to eliminating sources of error in experiments and providing you with stable, reproducible, and high-quality data.

Eliminating signal attenuation in the ultraviolet region: With excellent deep ultraviolet transparency, it ensures distortion free absorbance measurement at low wavelengths and accurately reflects sample concentration.

Ensure data reproducibility: Strictly control the optical path accuracy (tolerance up to ± 0.01mm) and window parallelism to prevent systematic deviations caused by differences in vessels.

Coping with harsh chemical environments: Excellent chemical inertness enables it to withstand strong acids (except hydrofluoric acid), organic solvents, and drastic temperature changes, extending its service life and reducing the risk of cross contamination.

As a professional manufacturer of quartz products, we are well aware that the quality of optical containers directly determines the success or failure of spectral analysis. Our product is made of high-quality synthetic quartz glass, which undergoes multiple processes such as precision annealing, cutting, grinding, and optical polishing. It has an extremely low coefficient of thermal expansion and excellent optical uniformity.

In addition to the standard products mentioned above, we also support non-standard customization. Whether you need special flange interfaces for integration into automation equipment or specific inner diameter capillary flow cells to adapt to microfluidic systems, our engineering team can provide you with one-on-one technical support and production services.

Typical Applications and Customer Cases

Our products are widely used in fields such as life sciences, pharmaceuticals, environmental monitoring, and chemical materials, helping numerous research institutions and enterprises overcome difficulties in analysis and testing.

Case 1: Upgrading drug dissolution monitoring in a well-known pharmaceutical company's QC laboratory

The laboratory faces the challenges of low efficiency and large data fluctuations in traditional manual sampling when conducting generic drug consistency evaluations. By introducing our customized high-temperature resistant quartz flow cell and integrating it into an automated dissolution testing system, they have achieved continuous online monitoring of the drug release process. This not only shortens the analysis time of a single batch by 30%, but also completely eliminates the operational errors caused by manual sampling, ensuring that drug quality control data fully complies with the strict requirements of the FDA and pharmacopoeias of various countries.

Case 2: Trace analysis of water quality by third-party environmental testing agencies

In daily monitoring of nitrate and heavy metal ions in surface water, due to the concentration of pollutants often being in the ppb (parts per billion) level, ordinary 10mm optical path colorimetric dishes are difficult to achieve the required detection sensitivity. We have provided the institution with a customized 50mm long path quartz colorimetric dish. According to the Bill Lambert law, an increase in optical path significantly amplifies weak absorption signals, enabling existing spectrophotometers to easily detect low concentrations of pollutants, effectively ensuring the safety assessment of local drinking water sources.

Case 3: Polymer Reaction Research by University Materials Science Teams

A research team from a certain university needs to study the structural changes of a new polymer under high temperature and high pressure conditions. Ordinary bonding processes cannot withstand high temperatures and are easily corroded by organic solvents compared to color dishes. We provided a special quartz reaction vessel (with a viewing window) manufactured using high-temperature melting integrated technology. This product not only withstands severe temperature shocks, but also has excellent optical transparency, allowing the team to successfully observe the microstructure evolution of the polymer in real time using laser scattering technology.
