Description
VG015 – 1.75 mL Glass Absorption Cuvette (Fused, 5 mm Path Length, 2 Windows, With Lid)
The VG015 is a precision optical glass cuvette designed for routine absorption spectroscopy in the visible and near-infrared regions.
With a 5 mm optical path length and a 10 mm internal width, it is ideal for medium-volume samples, providing stable optical performance at an economical cost. The fused glass construction ensures good durability and compatibility with most aqueous solutions and common laboratory solvents.
Key Features
- Sample volume: 1.75 mL — suitable for standard absorption measurements.
- 5 mm optical path length: reduces absorbance for high-concentration samples.
- 10 mm internal width: standard size compatible with most spectrophotometer holders.
- Optical glass material: high transparency in the visible to near-infrared range (350 – 2000 nm).
- Fused fabrication: robust and stable structure with good resistance to standard solvents.
- Wavelength range: VIS (350 – 2000 nm).
Typical Applications
- Visible light absorption spectroscopy
- Routine laboratory measurements
- Colorimetric assays and concentration determinations
- Education and QA/QC testing

About Glass Cuvettes
Optical glass cuvettes are an economical and durable option for visible light spectroscopy:
- Good chemical resistance for most aqueous and mild solvent systems.
- High transmission in the visible to NIR range.
- Not suitable for measurements below 350 nm (UV region).
- Fused structure provides stable optical alignment and easy cleaning.
Usage Notes
- Best for routine lab work, colorimetric assays, and general absorbance testing.
- Not recommended for strong acid/alkali or aggressive organic solvents.
- Provides stable readings with standard instruments.
Note: Glass cuvettes offer a cost-effective solution for visible range spectroscopy. For UV work, quartz cuvettes are recommended.
