Achieving accurate and reproducible spectroscopic data requires the use of high-quality optical vessels with precise path lengths and exceptional clarity. Laboratory glass cuvettes, manufactured from specialized materials like Suprasil quartz and optical special glass, are essential for UV-Vis analysis, fluorescence spectroscopy, and chemical research. As a core category within our optical instruments and microscopes and photometers ecosystems, these precision cells ensure minimal light interference.
Why Choose Professional Glass Cuvettes?
Our curated collection of optical cells is designed for analytical stability and wavelength-specific transparency:
- High-Precision Quartz Optics: We stock Hellma and Starna Scientific cuvettes made from Suprasil quartz glass, offering excellent transmission from 200 nm to 2500 nm.
- Versatile Volume Configurations: Select from macro (3500 µL+), semi-micro (700–1400 µL), and ultra-micro (10 µL+) cells to suit your specific sample availability.
- Standardized Path Lengths: Utilize cells with path lengths ranging from 1 mm to 100 mm, enabling precise absorbance measurements across various concentration levels.
- Secure Sample Containment: Most models include PTFE covers or stoppers to protect samples from contamination and prevent evaporation during long-duration kinetic studies.

Frequently Asked Questions
1. What is the difference between Quartz and Optical Special Glass?
Quartz glass (like Suprasil) is essential for measurements in the UV range (below 320 nm), whereas Optical Special Glass is typically used for the visible spectrum (320 nm to 2500 nm).
2. How should I clean my glass cuvettes?
Cuvettes should be rinsed immediately after use with a compatible solvent or high-purity water and wiped only with specialized lens paper to prevent scratches on the optical windows.
3. What are "Ultra-Micro" cells used for?
Ultra-micro cells, such as the Hellma 105.210 series, are designed for applications where sample volume is extremely limited, supporting volumes as low as 10 µL.
4. Do these cuvettes fit all spectrophotometers?
Standard macro and semi-micro cuvettes have an external width of 12.5 mm, which is the universal standard for most commercial spectrophotometers and photometers.
