Description
VAOB8 Fused Quartz Absorption Cuvette is a custom-dimension cuvette with an 8 ml volume and a 3 mm optical path length. It features a non-standard wide and tall geometry (72 × 42 mm), making it suitable for specialized laboratory setups and OEM instrument integration where conventional cuvette sizes are not ideal.
This model demonstrates our capability to produce customized quartz cuvettes tailored to match specific beam geometries, sample chamber sizes, or detection configurations. Its fused quartz construction provides high transmission, superior chemical resistance, and long service life for demanding analytical applications.
Key Features
- Custom outside dimensions (72 × 42 mm) — ideal for special instruments or OEM integration.
- 3 mm optical path — suitable for medium to high concentration samples.
- 8 ml capacity — supports larger sample handling compared to standard micro cuvettes.
- Fused quartz construction — excellent UV transparency, thermal stability, and solvent resistance.
- Broad wavelength range: 190–2500 nm — compatible with UV/VIS/NIR applications.
Typical Applications
- Customized spectroscopy system integration
- OEM instrument design and R&D
- Environmental and process analysis
- Biochemical and pharmaceutical testing
- Advanced analytical experiments requiring special geometry
Fused Fabrication Notes
- Fused quartz ensures high optical performance and thermal stability up to 600 °C.
- Not suitable for hydrofluoric acid (HF) or strong organic solvents like toluene and acetone.
- Powder seams may discolor over time but do not affect optical performance.
- Typical dimensional tolerance: ±0.06–0.08 mm.
