Performance characteristics and technical details
During the development of this cuvette, care was taken to ensure that all relevant factors for reliable laboratory analysis were met. It is designed for the spectral range between 320 nm and 2500 nm, ensuring accurate measurements in the UV, visible, and near-infrared ranges. Its high-quality workmanship enables accurate results with minimal sample volume and consistent quality.
Important technical data includes: • Type: 178.011-OS
• Material: Special optical glass (suitable for 320 nm – 2500 nm)
• Layer thickness: 10 mm
• Center height: 8.5 mm
• External dimensions (H x W x D): 38.5 x 12.5 x 12.5 mm
• Aperture diameter: 2 mm
• Volume: 30 µl
Two plane-parallel windows ensure optimal light entry and exit. In everyday laboratory use, users employ them for quantitative measurements of proteins, nucleic acids, or other light-absorbing substances. The cuvette also has inlet and outlet ports, which is a great advantage, especially for continuous flow measurements. This feature-rich design enables accurate measurements under changing sample conditions.
Manufacturing to high quality standards and the use of first-class raw materials ensure durability and stability over many years. The manufacturer takes common standards and certifications into account. Among other things, production complies with the requirements of DIN ISO 9001 for quality management. Users who demand consistently reliable measurement results benefit from this high standard.
Typical areas of application
- Biochemical laboratory analysis: With a low sample volume of only 30 µl and a layer thickness of 10 mm, the cuvette is ideal for sensitive measurements of enzyme activities or DNA concentrations.
- Flow measurement technology: Thanks to the two connectors, measurements can be performed in real time, with the liquid continuously flowing through the cell. This is particularly useful when concentrations or pH values change during the measurement.
- Environmental analysis: The compact design of the micro cuvette comes into its own when determining turbidity and suspended solids in small quantities of water samples.
- Pharmaceutical research: The precise absorption measurements are suitable for investigating pharmaceutical substances – for example, in solubility studies or stability tests.
FAQs
How can contamination be avoided?
Be sure to use suitable cleaning agents and rinse the microcuvette after each measurement cycle. Cleaning in an ultrasonic bath with mild, non-corrosive substances is recommended to remove residues.
Can particle measurements also be performed?
Yes, provided that the particle collective to be measured is within the appropriate size range. However, due to the 2 mm aperture, only very fine or dissolved particles can be reliably transmitted. For very coarse particles, a different solution is recommended.
Which light sources are suitable for measurements?
Due to the special optical glass, the transmittive wavelength range is between 320 nm and 2500 nm. Typical light sources such as deuterium lamps in the UV range or halogen lamps in the visible or near-infrared range are particularly suitable.
Is frequent insertion and removal of the cuvette in the measuring device problematic?
As long as the micro cuvette is handled with care, the measuring surfaces will remain in good condition. Especially if you change cuvettes frequently, use suitable clamping or holding devices that protect the glass.
Conclusion
This high-quality micro-cuvette with a layer thickness of 10 mm and a center height of 8.5 mm enables accurate and reproducible measurements with minimal sample consumption. The wide wavelength range and the connectors for flow measurements are particularly decisive advantages. Thanks to the robust special optical glass, the cuvette remains durable and precise even with regular cleaning and sterilization cycles. This makes it a reliable basis for demanding laboratory applications where accuracy, low sample volumes, and flexible usability are of utmost importance.
