Hellma Ultra Micro Cell 105.251-QS, 3 x 3 mm SD/8.5 mm ZH
The Hellma Ultra-Micro-Cuvette 105.251-QS, 3 x 3 mm SD/8.5 mm ZH has been specially developed for precise fluorescence measurements and other analytical applications in the laboratory. Thanks to its high-quality quartz glass construction and extremely low sample volume of only 45 µl, this cuvette is ideal for situations where sample material is precious, limited, or particularly sensitive. Compared to similar cuvettes on the market, it stands out above all for its precise manufacturing quality and extended wavelength range of 200 to 2500 nm.
Performance characteristics and areas of application
Thanks to its quartz glass, this model offers optimal transmission properties in the UV and Vis range. The ultra-low sample volumes prove to be a great advantage, especially in biotechnology, pharmaceuticals, chemistry, and materials research laboratories. The integrated design with three transparent windows and a polyethylene stopper ensures safe handling and protects the samples at the same time. The centering of the measuring aperture at 8.5 mm allows extremely precise alignment within the measuring device, enabling reproducible results to be achieved.
The ultra-micro cuvette is designed for measurements in spectrophotometers, fluorometers, and other optical analysis equipment. It can easily handle a wide variety of substances, from protein-based solutions and enzyme samples to pharmaceutical agents and sensitive dyes. The stable and lightweight design is particularly helpful when working with very small quantities of substances, as it minimizes the risk of contamination and sample loss. The precisely fitting stopper also prevents evaporation and contamination as far as possible.

FAQs
How is the cuvette cleaned properly?
It is best to clean it immediately after each use with a suitable, non-abrasive cleaning agent and rinse it several times with deionized water. It is then recommended to dry the cuvette gently or rinse it with suitable solvents.
What types of samples can be analyzed?
As a rule, aqueous and organic solutions can be analyzed equally well. Even sensitive substances such as proteins, peptides, or enzyme samples can be used without any problems as long as the quartz glass is not chemically attacked.
Is the cuvette suitable for UV spectroscopy?
Yes, the quartz glass used extends the transmission range from 200 to 2500 nm, enabling UV, Vis, and even NIR measurements.
Do users have to use a specific stopper?
The PE stopper supplied is custom-made and ensures optimum tightness. Alternative stoppers should only be used if they have the same dimensions and material properties and have been tested for quartz glass cuvettes.
Can only small sample volumes be used?
This ultra-micro cuvette is specially designed for small volumes of around 45 µl. Other cuvette models from the Hellma range are available for applications with higher sample quantities.
Conclusion
The combination of minimal sample requirements, a high wavelength transmission range, and solid quality manufacturing makes this quartz glass cuvette particularly attractive for demanding laboratory analyses. It delivers reliable and reproducible results even with the smallest sample volumes, is robust and easy to clean. Users in biotechnology, chemistry, or pharmaceuticals benefit from its sophisticated design and excellent optical properties. Overall, this product offers an optimal solution for precise fluorescence environments and other sensitive measurement procedures where every microliter counts.
