Specifications

The UNICO Quartz Rectangular Spectrophotometer Cuvette, 3mm pathlength, 1 ml capacity UV-Vis, each boasts a precise 3mm pathlength, a critical specification for determining the concentration of analytes via Beer-Lambert’s Law. Its nominal 1 ml capacity is more than adequate for most routine spectrophotometric analyses, though the actual fill volume is closer to the 0.35 ml specified in the product details, which is important to note for conservation of precious samples.

Constructed from high-quality quartz, this cuvette excels in transmitting light across the UV-Vis spectrum, typically from 190 nm up to 1100 nm. This broad transmission range makes it suitable for a wide array of experiments, from DNA/RNA quantitation to general chemical analysis. The rectangular shape is standard for most spectrophotometer sample holders, ensuring a secure and reproducible fit.

The 1 ml capacity quoted likely refers to the total volume it can hold, but the actual usable optical volume is less, which is a common convention in cuvette specifications. This is a key detail for users managing limited sample volumes. The 3mm pathlength is less common than the standard 1 cm, making this unit ideal for samples with high absorbance or when higher concentrations are involved, allowing for accurate readings without excessive dilution.

Performance & Functionality

This UNICO quartz cuvette performs its primary function – accurate light transmission for spectrophotometric analysis – exceptionally well. The 3mm pathlength is particularly effective for samples with high optical densities, where a standard 1 cm pathlength cuvette would require significant dilution, potentially introducing new sources of error. This unit allows for more concentrated samples to be analyzed directly.

Its main strength lies in the consistent spectral transmission provided by the quartz material, resulting in reliable and reproducible absorbance readings. The minimal stray light and excellent transparency in the UV range are crucial for many biological and chemical assays. A minor consideration is the actual usable volume versus the stated capacity; users need to be aware that the optical path is defined by the 3mm width, not necessarily by filling it to the brim.

Overall, the performance meets and often exceeds expectations for a cuvette of this specification. It reliably delivers accurate data, which is paramount in any laboratory setting where precision is key.
