cuvette for spectrophotometer

Description :

Shared Characteristics Material: Both are made of polystyrene, which provides good optical clarity in the visible spectrum (340-800 nm). Wavelength Range: Both are suitable for visible-range spectrophotometry but are limited in UV applications below 300 nm due to polystyrene’s absorbance. Path Length: Both typically have a standard 10 mm path length, making them compatible with most spectrophotometers without adjustments. Chemical Compatibility: Both are compatible with aqueous solutions and diluted acids but should avoid strong organic solvents (such as acetone or chloroform), which can degrade polystyrene. Disposability: Both types are usually disposable for single-use to prevent contamination, and they’re cost-effective compared to quartz or glass cuvettes. Use Cases: Both are suitable for visible light absorbance measurements in applications like colorimetric assays, biological and environmental testing, and teaching labs due to their affordability and ease of handling. Storage and Handling: Both types should be stored away from UV light and handled carefully to avoid fingerprints or scratches on the optical surfaces. In essence, both the 4 mL and 2 mL polystyrene cuvettes offer similar functional qualities, with the primary difference being their sample capacity (volume), which affects their suitability based on available sample volume. 100pcs packing image
