Frequently Asked Questions What wavelength range do these UV-grade PMMA cuvettes support? UV-grade PMMA transmits well across the visible spectrum and into the near-UV, typically usable from about 300 nm upward. For deep-UV work below roughly 280 nm, quartz cuvettes remain the preferred choice. What is the usable volume and path length? These 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. Are these cuvettes reusable? They 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. Can I use organic solvents in these cuvettes? PMMA tolerates aqueous buffers and dilute acids and bases well, but is incompatible with acetonitrile, aromatic, and chlorinated solvents. For solvent-heavy methods, select glass or quartz cells instead. { "@context": "https://schema.org", "@type": "Product", "name": "Semi-Micro 2.5 mL UV-Grade PMMA Cuvettes, 2 Clear Sides, 500/Case", "brand": { "@type": "Brand", "name": "Globe Scientific" }, "sku": "112147", "description": "Disposable semi-micro cuvette, 2.5 mL, UV-grade PMMA with 2 clear sides, 100/tray, 5 trays per case (500/case).", "offers": { "@type": "Offer", "priceCurrency": "USD", "price": "175.10", "availability": "https://schema.org/InStock", "seller": { "@type": "Organization", "name": "labsupplies.com" } } } { "@context": "https://schema.org", "@type": "FAQPage", "mainEntity": [ { "@type": "Question", "name": "What wavelength range do these UV-grade PMMA cuvettes support?", "acceptedAnswer": { "@type": "Answer", "text": "UV-grade PMMA transmits well across the visible spectrum and into the near-UV, typically usable from about 300 nm upward.
