- Type: Bonded, For Aqueous Samples Only
Description
VLBM25 Ultra Micro Cuvette is a bonded quartz cell designed for high-sensitivity absorbance measurements with a 0.5 mm optical path length. It requires only 25 μL of sample and features 2 clear optical windows, making it ideal for concentrated or precious samples in UV/VIS spectroscopy (190-2500 nm).
The bonded fabrication is cost-efficient and allows for fast customization, making it suitable for research and OEM applications that require flexible turnaround without compromising basic optical performance. The non-detachable structure provides stable sealing and reliable measurement consistency.
Typical Applications
- High-concentration sample analysis
- UV/VIS absorbance with short path length
- Biological and chemical assays with limited sample volume
- Analytical and OEM instrument integration
- High-throughput screening and routine QC
Key Features
- 0.5 mm optical path – suitable for medium to high absorbance
- Only 25 μL required – ideal for limited samples
- Bonded fabrication – fast customization at lower cost
- Stable structure with good optical transmission
- UV/VIS transmission range: 190 – 2500 nm
