Hellma Large Cuvette 700.010-OG, 20 mm layer thickness
This cuvette is particularly suitable for microscopic observations and also offers an ideal solution for precise measurement applications in the laboratory. Thanks to its high-quality optical glass, it has a broad transmission range from 360 nm to 2500 nm, making it suitable for a wide range of spectroscopic processes. Compared to similar products, it scores points for its robust design and generous interior space, which allows you to work with larger sample volumes.
Performance characteristics and technical details
The design without a lid allows easy access to samples and facilitates use in special analysis procedures that require a quick response to sample changes. The generous internal cross-section is also ideal for measurements with light paths of 20 mm. Here are the most important technical data in compact form:
• Type: 700.010-OG
• Material: Optical glass (spectral range: 360 nm – 2500 nm)
• Volume: 56,000 µl
• Layer thickness: 20 mm (+0.2 tolerance)
• External dimensions (H × W × D): 82 × 44.4 × 24.4 mm
• Internal dimensions (H × W × D): 80 × 40 × 20 mm
• Without cover
The optical glass ensures high transmission in the UV/VIS and NIR ranges. Because the material is characterized by particularly low intrinsic absorption, there is hardly any interference in sensitive measurements. This allows maximum accuracy to be achieved even at low concentrations, for example in photometric processes or fine color distinctions in industrial quality assurance processes.
The layer thickness of exactly 20 mm allows reliable comparative measurements in many areas, especially when a precise light path length is required. Thanks to the manufacturing tolerance of only +0.2 mm, the measurement results are consistent, which is essential for laboratories and research institutions. With a sample volume of up to 56,000 µl, even larger or more viscous samples can be measured optimally. However, to avoid contamination during transport or storage, a separate closure option is recommended if this is necessary for the respective application.
Certifications and standards
The materials and manufacturing methods used comply with current guidelines for quality assurance in laboratory environments. As a rule, cuvettes in research institutes and industrial laboratories bear a CE mark, which signals conformity with European safety requirements. Optical glass designed for this spectral range typically meets DIN standards for light transmission and precision of the light path length, ensuring accurate measurements in the field of photometry and spectroscopy in accordance with DIN standards.
Application examples
• Quality assurance in the food industry: Measuring and comparing color pigments in liquids such as fruit juices or sauces.
• Research and development in the pharmaceutical industry: Analysis of chemical reactions, for example when dissolving active ingredients.
• Process monitoring in chemistry: Spectroscopic checks of clarity, transmittance, and color in industrial intermediate products.
• Microscopic pathology: Examination of tissue samples or cell cultures using high-resolution microscopy.
FAQs
What is the best way to clean the cuvette?
Use neutral cleaning agents or a weak solution of ethanol and water if possible. Be careful not to use abrasive materials to avoid damaging the sensitive glass surfaces.
Is a lid available?
The model is supplied without a lid as standard, but a suitable cap is often available as an optional accessory. Depending on the application, this may be useful to reduce contamination and evaporation.
Is this cuvette also suitable for UV measurements?
Yes, it is designed for the UV range from approximately 360 nm. For shorter wavelengths below this limit, quartz glass cuvettes are recommended.
How does the layer thickness affect my measurement?
The layer thickness determines the light path through the sample. A precise and stable thickness of 20 mm guarantees reproducible measurements and minimizes measurement errors in comparative analyses.
Conclusion
This large cuvette combines versatility and precision, making it suitable for both microscopic examinations and demanding spectrophotometric measurements. The carefully manufactured optical glass with high transmission and low manufacturing tolerance enables accurate results and professional use in a wide range of laboratory applications. In addition, the large internal volume facilitates complex analyses and makes this cuvette an excellent basis for reliable, reproducible results in scientific and industrial environments.
