Hellma Ultra Micro Cuvette 105.210-QS, 5 mm SD/8.5 mm ZH
This ultra micro cuvette was specially developed for precise absorption measurements with extremely small sample volumes. Thanks to its excellent workmanship using high-quality quartz glass, it offers outstanding light transmission and exceptional resistance to chemical substances compared to conventional cuvettes. Anyone who performs measurements in the UV/VIS range and wants to make efficient use of minimal sample quantities will find a highly specialized solution here that is also characterized by durability and reliability.
Versatile properties for precise measurements
The following overview summarizes the key features and shows why this cuvette is preferred in demanding laboratory environments:
• Quartz glass with a wide transmission range from 200 nm to 2500 nm
• Layer thickness of 5 mm for optimum sensitivity
• Center height of 8.5 mm for compatibility with numerous devices
• External dimensions of 40 x 12.5 x 12.5 mm for universal handling
• Easy sample application thanks to open-top design
• Dual window for precise light measurement
• Minimum volume of only 2.5 µl
In addition, the cuvette features a round aperture of 0.8 mm, which enables precise focusing of the light beam and thus even more reliable data collection. The special shape was deliberately chosen to easily accommodate even the smallest sample volumes and allow for quick pipetting. This allows both highly concentrated and sensitive samples to be examined efficiently.
The robust construction of the quartz glass protects against scratches and minor mechanical impacts, which significantly increases the service life of this ultra-micro cuvette. In addition to a high level of temperature and chemical resistance, the optimized shape reduces any reflections, ensuring an interference-free measurement environment.
Certifications and standards
Many laboratories have strict guidelines regarding reproducible results. Quartz cuvettes of this type are usually based on DIN and ISO standards in the field of measurement technology. They are often part of an ISO 9001-compliant manufacturing process and are subject to strict quality controls. This guarantees consistent accuracy and repeatability, especially for UV/VIS analyses in biotechnology, pharmacy, or chemistry. For users, this means maximum reliability in daily use—a crucial factor in sensitive areas such as pharmaceutical controls or forensic analyses.
Specific application examples
- Protein analysis with small sample volumes: The cuvette allows protein structures or concentrations to be examined even when only minimal amounts of solvent are available.
- Nucleic acid determination in genetic research: The high light transmittance in the UV range allows DNA or RNA samples to be quantified with the highest precision.
- Absorption measurements of dyes: In industrial quality control, spectral measurements provide accurate information about color nuances and concentrations.
- Photometric investigations in chemical laboratories: Sensitive substances, such as certain enzymes or medications, can be measured in a targeted manner to obtain reliable results for research and development.
Due to the high purity of quartz glass, this cuvette is also resistant to numerous chemicals, including many acids and bases. This makes it universally usable for a wide variety of laboratory applications without the risk of contamination or damage.
Frequently asked questions
What is the best way to clean the cuvette?
The easiest way is to rinse it with distilled water and mild detergent. It can then be rinsed with ethanol or acetone and left to dry. A suitable cleaning bath is recommended for stubborn residues.
Is the cuvette suitable for highly concentrated solutions?
Yes, thanks to the resistant quartz glass, it can also be used for concentrated chemicals. At the same time, the compact geometry enables precise measurements of samples with a low layer thickness.
Does the aperture require special attention?
The round aperture of 0.8 mm is specially designed for precise light irradiation. This achieves focused light guidance, which leads to accurate measurement results.
Can the cuvette be labeled?
The quartz glass is robust enough to be carefully marked on the outer surface using laser engraving or other marking methods. This allows clear labeling for different samples or calibration standards.
Conclusion
This cuvette stands for accuracy, durability, and remarkable flexibility in various measurement applications. With its wide wavelength range, high material purity, and clear focus on minimal sample volumes, it is ideal for demanding investigations in research laboratories and industrial environments alike. The combination of excellent light transmission, chemical resistance, and space-saving design makes it a first-class choice when reliability and reproducible results are of the highest priority. This makes the Hellma Ultra Micro Cell 105.210-QS, 5 mm SD/8.5 mm ZH an indispensable tool for highly sensitive analytical procedures.
