The Labmart Type B3 Ultra Micro Fluorescence Cuvette is a precision quartz optical cell designed for fluorescence and fluorometric measurements using very small sample volumes. It features four polished windows, a 10 mm path length, 15 mm Z-height, black-wall construction and PTFE closure options, making it suitable for sensitive fluorescence measurements where sample conservation is important.

Product Overview

The Type B3 Ultra Micro Fluorescence Cuvette is designed for fluorescence applications requiring very low sample volumes while maintaining four-sided optical access.

The standard configuration features a 10 mm path length, 15 mm Z-height, black-wall quartz construction and dimensions of 12.5 × 12.5 × 45 mm. Multiple ultra-micro sample volumes are available, from 10 µL to 400 µL.

The cuvette is available with either a PTFE cover or PTFE stopper, with the listed configurations supplied as matched pairs.

The black-wall design is particularly important for fluorescence applications because masking unwanted light paths can help preserve measurement sensitivity. The correct Z-height should be selected according to the centre-beam height of the fluorescence instrument.
