Answer:5 mm, with a nominal 450 µL cell capacity.
Answer:Yes. The package contains one matched pair of quartz semi-micro cells with PTFE stoppers.
Answer:At the same concentration, ideal absorbance is half that of a 10 mm cell under Beer–Lambert conditions.
Matched Quartz Semi-Micro UV-Vis Cuvettes with a 5 mm optical path support absorbance measurements when a shorter path length or reduced sample volume is appropriate. The far-UV quartz construction provides optical performance suited to ultraviolet and visible spectroscopy. Each rectangular cell has a nominal 450 µL capacity, a 4 mm aperture and self-masking black walls that help control stray light around the sample compartment. The matching pair improves consistency in comparative or dual-beam measurements, while PTFE stoppers help limit contamination and evaporation during analysis. The cells fit compatible Agilent Cary UV-Vis spectrophotometers. Use the correct orientation and ensure that optical faces remain clean and unscratched. Fill both cells to cover the optical beam, remove bubbles and select reference solutions that match the sample solvent matrix. A 5 mm optical path produces half the absorbance of a 10 mm path for the same analyte concentration under Beer–Lambert conditions, so calculation methods must use the actual path length.
