For deep-UV work below roughly 280 nm, quartz cuvettes remain the preferred choice.\u003c\/p\u003e\n\u003ch3\u003eWhat is the usable volume and path length?\u003c\/h3\u003e\n\u003cp\u003eThese semi-micro cells hold up to 2.5 mL and feature a standard 10 mm path length with a reduced inner chamber, allowing accurate readings on smaller sample volumes than a standard macro cuvette.\u003c\/p\u003e\n\u003ch3\u003eAre these cuvettes reusable?\u003c\/h3\u003e\n\u003cp\u003eThey are disposable and intended for single-use to prevent cross-contamination and avoid solvent-induced clouding. Buying in the 500-count case keeps per-cuvette cost low for high-throughput workflows.\u003c\/p\u003e\n\u003ch3\u003eCan I use organic solvents in these cuvettes?\u003c\/h3\u003e\n\u003cp\u003ePMMA tolerates aqueous buffers and dilute acids and bases well, but is incompatible with acetonitrile, aromatic, and chlorinated solvents.
