Hellma Macro Cell 110-QS, 5 mm layer thickness
This quartz glass cell impresses with its high-quality workmanship and is specially designed for precise absorption measurements in the UV and visible wavelength range. Due to its excellent optical properties and low dead volume, it offers particularly high measurement accuracy and reproducibility compared to conventional cuvettes. This makes it ideal for applications in areas such as pharmaceuticals, biotechnology, or chemical research, where reliable and fast results are essential. Thanks to its robust quartz glass, this solution can withstand even demanding conditions. Its high stability and maximum transparency in the spectral range from 200 nm to 2,500 nm ensure extremely accurate and reproducible results. The included PTFE (polytetrafluoroethylene) stopper securely seals your samples while minimizing potential contamination.
Features and special characteristics
• Type: 110-QS (specially designed for demanding applications in the UV/Vis range)
• Quartz glass for 200 nm – 2,500 nm: Ideal for measurements across a wide spectrum
• Layer thickness: 5 mm for small sample volumes and accurate absorption values
• Volume: 1,750 µl – sufficient for a wide range of samples without unnecessary consumption of expensive reagents
• External dimensions (H x W x D): 46 x 12.5 x 7.5 mm, compact yet spacious enough for macro measurements
• Internal width: 9.5 mm, suitable for a wide variety of pipetting and dosing approaches
• Base thickness of 1.5 mm: Ensures stability and consistent results
In addition, the cuvette has two opposite windows, which further improves the light transmission of the quartz glass. In combination with the robust PTFE stopper, samples remain securely sealed, while easy handling is guaranteed despite repeated opening and closing. PTFE is particularly suitable for laboratories that frequently work with aggressive chemicals, as it is highly resistant and prevents unwanted reactions with the sample. Quartz glass itself is known for its exceptional purity and resistance to temperature fluctuations. This makes it a preferred choice in a wide variety of research environments. Due to its low autofluorescence and suitability for the entire UV-Vis range, even sensitive substances can be reliably analyzed. Another advantage is that it is easy to clean: the smooth surface of quartz glass prevents sample residues from adhering, virtually eliminating cross-contamination.
Hellma cuvettes stand for the highest quality and precision, which is underpinned by strict quality assurance. These products often meet or exceed relevant industry standards that apply to optical instruments and laboratory accessories. These can include DIN and ISO standards relating to material quality, manufacturing tolerances, and optical properties. Hellma always ensures consistently high quality of quartz glass and manufacturing in order to maintain reliable measurements in sensitive analytical procedures.
Application examples
• Determination of protein concentration at 280 nm, such as the analysis of albumin in biotechnology
• Examination of nucleic acids at 260 nm to test the purity of DNA samples in molecular biology laboratories
• Quantitative measurement of dye solutions in chemical research, for example in the manufacture of indicators or diagnostics
• Precise detection of active ingredients in pharmaceutical applications, especially in the quality control of antibiotics or hormones. In addition to these specific examples, the cuvette is generally suitable for any process in which the optical density of a liquid is determined in the UV or visible range. The robust design also allows it to be used in environmental and water analysis, for example to determine certain pollutant concentrations.
FAQs
How do I clean the cuvette properly?
First rinse the cuvette with the solvent used to remove sample residues. Then clean thoroughly with mild laboratory cleaners or concentrated acid, depending on the protocol. Be careful not to scratch the material with abrasive sponges.
Is the macro cuvette suitable for higher temperatures?
Quartz glass has a high temperature limit, but sharp temperature changes should be avoided. Slow adjustment to the desired temperature is recommended to prevent damage.
Can I use different solvents?
Yes, quartz glass is highly resistant to a wide range of chemicals. The PTFE stopper supplied is also suitable for most common solvents without the risk of interaction.
Can the cuvette be used multiple times?
Yes, with proper handling and thorough cleaning, it can be used repeatedly over a long period of time. The optical properties are retained as long as the glass is not damaged.
