Hellma Macro Cell 100-QX, 10 mm layer thickness
This cell is highly regarded in laboratories and research facilities due to its precise manufacture from high-quality quartz glass for the UV-VIS range. It is primarily used for absorption measurements that require the best possible light transmission and precise measurement accuracy. As this model has a particularly long service life and can be easily integrated into existing laboratory systems, it is an exemplary choice compared to similar cuvettes on the market.
Versatile features for the highest demands
This model offers a robust design and is suitable for the wavelength range from 200 nm to 3500 nm. It thus covers a wide range of analytical applications – from the ultraviolet to the near-infrared range. Another advantage is the PTFE hinged lid. PTFE (polytetrafluoroethylene) is characterized by its high chemical resistance and excellent sealing properties, making it indispensable for sensitive samples. The hinged lid minimizes unwanted leakage of liquids, ensuring that even volatile substances remain safely inside.
The quartz material of this cuvette enables precise measurements in spectrometry and photometry. In addition, the cuvette is designed to ensure a consistent layer thickness of 10 mm. This allows measured values to be efficiently compared and reproduced, even in extensive measurement series. In addition, the two-window design ensures optimal transmission and precise light passage. Technical data at a glance • Type: 100-QX • Material color code: QX (quartz glass 300)
• Spectral range: 200 nm–3500 nm
• Layer thickness: 10 mm
• Volume: 3500 µl
• External dimensions (H × W × D): 45 × 12.5 × 12.5 mm
• Base thickness: 1.5 mm
The internal width of 9.5 mm and the solid quartz glass are coordinated so that even higher sample volumes can be measured reliably. The uniform light path ensures reproducible results. The quartz glass itself has very low intrinsic absorption and is therefore ideal for reducing disruptive measurement deviations.
As the cuvette is generally subject to intensive use, it is insensitive to temperature fluctuations that can occur during thermal processes. Its high degree of purity, due to the material used, also makes it interesting for pharmaceutical and biotechnological applications. Certifications such as CE or DIN standard requirements are common in this product area, ensuring safe and standard-compliant use even for demanding tasks, for example in accredited laboratories.
Specific application examples
• Analysis of nucleic acids (DNA, RNA) in molecular biology, where precise quantification is essential.
• Determination of proteins or enzyme activities where reproducible measurements in the UV range are required.
• Water and environmental analysis for the detection of minute amounts of contaminants or pollutants.
• Photometry in chemical laboratories, for example to detect color reactions in metal ions or organic compounds. Thanks to its generous volume, the cuvette is also suitable for concentrated solutions or samples with varying pH values. The chemical resistance of quartz and PTFE ensures that even aggressive substances such as concentrated acids or alkalis do not affect the material.
FAQs
What is the best way to clean the cuvette?
Mild detergents or special cuvette cleaners have proven effective for cleaning. Rinse the cuvette thoroughly with deionized water and dry it carefully with a lint-free cloth to avoid streaks.
Can the cuvette be used for highly concentrated acids or bases?
Yes, thanks to its PTFE folded lid and stable quartz glass, it is extremely resistant to chemical influences. However, before each use, you should check whether the chemical is compatible with quartz and PTFE.
Which specific light sources are suitable for measurements?
Due to the wide spectral range (200 nm to 3500 nm), both deuterium and halogen lamps as well as xenon light sources can be used. The cuvette is particularly suitable for UV-Vis spectrometers and NIR analyses.
Does a specific fill level have to be observed?
You will obtain a stable measurement signal if the cuvette is completely filled and the light path is passed through evenly. Make sure that no air bubbles are trapped, as these could distort the measurement result.
How can the cuvette be securely closed?
The PTFE hinged lid closes without additional tools or twist mechanisms. Place it straight on and apply light pressure to ensure an optimal fit.
Conclusion
The combination of quartz glass, PTFE closure, and wide wavelength range makes this cuvette a reliable solution for demanding spectral analyses. From nucleic acid analysis and protein determination to demanding sensor tasks, it offers stable, precise measurements and is robust enough to withstand the high demands of everyday laboratory work. If you need a durable and versatile cuvette, this is a professional option that offers impressive quality and easy handling.
