Funnel-Top Micro Quartz Cuvette
The Funnel-Top Micro Quartz Cuvette is a micro-volume optical cell fabricated from UV-grade quartz glass. Its funnel-shaped top inlet guides the sample smoothly into a narrow capillary measuring channel, enabling accurate UV-Vis absorbance measurements with only a very small sample volume. Two precision-polished optical windows deliver high transmission from the deep-UV to the near-infrared (190–2500nm), while the frosted non-optical surfaces reduce stray light and ease handling. With its standard 12.5×12.5×45mm footprint and 15mm beam center height, the cuvette is directly compatible with conventional spectrophotometer cuvette holders, making it ideal for trace-sample analysis such as DNA/RNA quantification and protein concentration measurement.
