Laboratory and Chemical ApplicationsQuartz round screw-top cuvettes are laboratory vessels made from fused quartz, characterized by high light transmittance, high-temperature resistance, and chemical corrosion resistance. They are suitable for spectroscopic analysis in the ultraviolet to visible light regions. These cuvettes are designed with a round shape and a screw-top to facilitate sealing and secure placement, and are commonly used for precise measurements of varying sample volumes.

High Light Transmittance
The quartz material offers high light transmittance in the ultraviolet to visible light regions, which is essential for spectroscopic analyses requiring precise measurements within these wavelength ranges.
High-Temperature and Chemical Corrosion Resistance
Quartz cuvettes are able to withstand high temperatures and exhibit good resistance to most chemical reagents, allowing them to maintain performance even under harsh experimental conditions.
Screw-Top Design
The screw-top design allows for sealing of the cuvettes, reducing sample evaporation and contamination. It also facilitates secure mounting of the cuvettes on spectrophotometers, ensuring the stability of measurements.
Orientation Considerations
Quartz round screw-top cuvettes may have an orientation, and proper placement according to the specific model and markings is necessary to minimize measurement errors and ensure the accuracy of experimental results.
Application Scenario
Use with Circular Dichroism Spectrometers
Quartz round screw-top cuvettes are commonly used with various models of circular dichroism spectrometers and other analytical instruments, particularly suitable for circular dichroism spectroscopic analysis.
Infrared Spectroscopic Analysis
In infrared spectroscopic analysis, quartz cuvettes play a crucial role, primarily for loading reference and sample liquids. Their high light transmittance and good chemical stability ensure the accuracy and reliability of the analysis results.
Measurement of Oil in Water
Quartz cuvettes are essential components of infrared oil-in-water analyzers and Fourier transform infrared (FTIR) spectrometers, mainly used for the determination of oil in water.
Laboratory Spectroscopic Analysis
Quartz cuvettes, due to their superior light transmission, are widely used in laboratory spectroscopic analysis, including measurements in the ultraviolet to visible light regions, as well as for ultraviolet spectroscopic analysis requiring high transmittance.
The high light transmittance of quartz cylindrical cuvettes in the ultraviolet region is essential for experiments requiring precise measurements in this wavelength range. Many biomolecules and chemical substances have characteristic absorptions in the ultraviolet region, which are crucial for their quantitative analysis and identification.
When using quartz cuvettes, avoid touching the optical surfaces to prevent contamination. Thoroughly clean and properly store them before and after use to maintain their performance. Also, because quartz material is fragile, handle with care to prevent damage.
When cleaning quartz cuvettes, gently wipe with a mild detergent and a soft cloth, avoiding hard brushes or abrasives that could scratch the surface. After cleaning, thoroughly rinse and air-dry or wipe with a lint-free cloth. For long-term storage, store them in a suitable cuvette box, avoiding direct sunlight and high-temperature environments to extend their lifespan.

Frequently asked questions
Quartz glass is a hard and brittle material with excellent physical and chemical properties, extremely high mechanical hardness, good electrical insulation, high temperature and corrosion resistance, low and stable delay performance, good light transmittance, etc. It is widely used in semiconductors, optics, electricity, chemistry, aerospace, automobiles and other fields. Hard and brittle materials are difficult to process, and many fields urgently need cutting processes with small edge collapse, less material loss, low cross-section roughness, and a wide cutting thickness range. The traditional cutting method of quartz glass is mechanical cutting, that is, wheel cutting. Non-traditional cutting methods include water jet cutting, electrochemical discharge wire cutting, continuous laser cutting, etc. Mechanical cutting has low cost, but the contact between the wheel and the material causes large tool wear, and the material is easily contaminated by the tool. Quartz glass is prone to edge collapse, microcracks, and residual stress, which affects the strength and performance of the material! It is difficult to achieve curve cutting and requires post-processing, such as grinding and polishing. Laser cutting does not directly contact the material, has no contact stress, and can perform complex curve cutting. Picosecond laser has the advantages of small spot diameter, high precision, short action time with the material, and small action area, and is suitable for the processing of hard and brittle materials.
