UV transparent quartz cuvette
The UV transparent quartz cuvette, also known as the quartz absorption cell or quartz sample cell, is the core vessel used in ultraviolet-visible spectrophotometers to hold liquid samples to be tested. It is made of high-purity fused silica (SiO₂) material through precise optical processing techniques, featuring extremely high optical uniformity and accurate optical path length.
Unlike ordinary glass or plastic cuvettes, quartz material endows it with unparalleled optical properties: it has extremely high light transmittance in the ultraviolet region (190nm - 380nm), visible light region (380nm - 780nm), and even the near-infrared region (780nm - 2500nm) (usually better than 80%@190nm). This means that it hardly absorbs the light of these bands, thus ensuring the absolute accuracy and reliability of the measurement data. It is an essential experimental tool for conducting precise quantitative and qualitative analysis.
The quartz cuvette series we offer, with its outstanding quality, exquisite craftsmanship and consistent reliability, is committed to being a strong support for the accuracy of your laboratory data.
What problems can we solve
In spectral analysis, any tiny error can lead to a huge deviation in the experimental results. Poor-quality or inappropriate cuvettes are common but often overlooked sources of error. Our UV transparent quartz cuvettes are designed to thoroughly solve the following problems:
1. Absorption interference problem in the ultraviolet band:
Ordinary optical glass has strong absorption in the ultraviolet band (especially <340nm), resulting in severe attenuation of the light signal and making it impossible to conduct accurate ultraviolet band tests (such as nucleic acid and protein concentration determination).
Solution: High-purity quartz material has an extremely high light transmittance from 190nm deep ultraviolet, making it perfectly suitable for experiments with strong ultraviolet absorption, ensuring no signal loss or distortion.
2. Issues of inaccurate measurement data and poor repeatability
Problem: Inaccurate optical path length of the cuvette, non-parallel window plates, or internal stress can lead to systematic deviations in absorbance values. Data from different cuvettes cannot be compared, and the results of repeated experiments are inconsistent.
Solution: We adopt precise processing and strict quality inspection to ensure that the optical path of each cuvette (such as 10.00mm) is accurate and error-free, the window height is parallel and stress-free, guaranteeing the accuracy of the data and excellent repeatability.
3. Chemical corrosion and sample contamination issues:
Some strong acids, strong bases or organic solvents can corrode glass or plastic cuvettes, not only damaging the vessels but also contaminating precious samples, leading to cross-contamination and experimental failure.
Solution: Fused quartz has extremely high chemical stability and corrosion resistance (except for hydrofluoric acid and hot phosphoric acid), can withstand most acids, alkalis and organic solvents, is easy to clean, and greatly reduces the risk of pollution.
4. Cracking problems caused by poor thermal stability:
In experiments that require temperature changes or high-temperature reactions, ordinary cuvettes may crack due to uneven thermal expansion and contraction.
Solution: Quartz material has an extremely low coefficient of thermal expansion, excellent thermal stability, and can withstand drastic temperature changes, making it suitable for reaction kinetics studies that require temperature control.
Main application fields
With its outstanding performance, UV transparent quartz cuvettes are widely used in all fields where the absorbance of liquid samples needs to be precisely measured:
