Hellma Ultra Micro Cell 105.201-QS, 10 mm SD/15 mm ZH
The Hellma Ultra-Micro Cell 105.201-QS, 10 mm SD/15 mm ZH is specially designed for precise photometry applications where only small sample volumes are available. Thanks to its exceptional manufacturing quality from quartz glass, this cuvette is particularly well suited for demanding measurements in research laboratories and industrial environments. It stands out from conventional cuvettes due to its robust construction and the low sample volume required—an important advantage when substances such as nucleic acids, proteins, or other sensitive analytes need to be researched or monitored.
Versatile properties for precise analyses
This ultra-micro cuvette is made of high-quality quartz glass, which enables a wide transmission range from 200 nm to 2500 nm. This makes it ideal for absorption measurements in a wide wavelength range. In addition to its universal application, it has a compact design and comes with a polyethylene (PE) stopper that securely seals the sample and protects it from contamination.
Another special feature is its small internal dimensions, which require only the smallest sample quantities. The cuvette thus saves valuable resources without compromising measurement quality. Reliable production by the long-established manufacturer Hellma and extensive quality controls ensure that, in addition to durability, the measured values are reproducible at all times.

In addition to these core values, the cuvette provides a reliable basis for highly accurate results in all spectral bands. This makes it ideal for UV-VIS spectroscopy and other photometric methods in which sensitive samples need to be handled as gently and efficiently as possible.
The smooth inserts and precisely machined edges enable uniform light penetration, which is crucial in laboratory situations. The PE stopper supplied protects against evaporation or contamination and contributes to the long-term stability of the sample. These factors play an important role when it comes to quality control of highly sensitive products, for example.
Certifications and standards
The manufacturer attaches particular importance to consistent and high manufacturing quality. Most production facilities are therefore subject to strict standards such as DIN ISO 9001. This ensures that every cuvette meets the required standards and that precisely reproducible measurement results are possible at all times. Those who require maximum precision for their measurements can rely on these quality controls.
Specific application examples
- Analysis of nucleic acids: The small sample volume allows DNA or RNA samples to be measured cost-effectively and accurately without wasting valuable substance.
- Protein quantification: Protein samples are often only available in very small quantities. The ultra-micro cuvette ensures reliable determination of their concentration.
- Quality control in the pharmaceutical industry: Particularly suitable for sensitive substances or process monitoring in the GMP environment.
- Food analysis: Whether dyes, vitamin content, or other ingredients—this cuvette enables accurate and fast testing even with limited sample volumes.
Frequently asked questions (FAQ)
How is the cuvette cleaned correctly?
Depending on the type of sample, cleaning can be carried out with suitable solvents or mild cleaning agents. The cuvette should then be rinsed with ultrapure water or high-purity solvent and dried thoroughly to avoid scattered light from residues.
Is there a risk that the small sample volume will be measured inaccurately?
No, the minimum sample volume required is precisely defined and ensures accurate measurement. The quartz glass cuvette is designed so that the incident measurement light is guided evenly through the sample, enabling reliable results even with very small volumes.
How long does this product typically last?
When properly cleaned and stored, the cuvette is extremely durable and retains its optical properties for many years. Quartz glass is abrasion-resistant and resistant to chemical influences, which significantly increases its service life.
Does the PE stopper always have to be used?
The stopper ensures a clean seal and protects the sample medium from contamination or evaporation. For high-precision measurements or measurements over a longer period of time, its use is advisable to ensure optimal conditions.
Conclusion
This ultra-micro cuvette offers an ideal solution for all laboratories, research institutions, and industries that want to measure highly sensitive substances in small quantities. With its solid properties in terms of material quality and reliable standards, it enables accurate and reproducible results in a wide range of spectral areas. Its robust design and secure closure with a PE stopper ensure that the sample is analyzed with as little alteration as possible, which is crucial in scientific and industrial applications. For those who demand the highest standards of reliability, precision, and functionality, this cuvette is the perfect tool for demanding photometric measurements.
