Each cuvette provides a fixed 10 mm path length, the standard geometry for most benchtop UV-Vis spectrophotometers and absorbance calculations. What spectral range are these cuvettes suitable for? The optical-grade plastic supports visible-range measurements and many near-UV applications. For deep-UV work below the polymer cutoff, verify the wavelength against your assay requirements. Are these cuvettes reusable or disposable? They are intended primarily as economical single-use disposables, which eliminates carryover and cleaning between samples. Limited reuse with aqueous buffers is possible if rinsed promptly. Are these cuvettes compatible with organic solvents? They perform well with aqueous buffers and dilute acids or bases. Acetonitrile, aromatic, and chlorinated solvents are not recommended due to potential attack on the polymer. { "@context": "https://schema.org", "@type": "Product", "name": "Square Spectrophotometer Cuvettes, 4.5 mL, 10 mm Path Length", "brand": { "@type": "Brand", "name": "Globe Scientific" }, "offers": { "@type": "AggregateOffer", "priceCurrency": "USD", "lowPrice": "112.50", "highPrice": "179.20", "offerCount": 2, "offers": [ { "@type": "Offer", "sku": "111157", "price": "179.20", "priceCurrency": "USD" }, { "@type": "Offer", "sku": "111137", "price": "112.50", "priceCurrency": "USD" } ] } } { "@context": "https://schema.org", "@type": "FAQPage", "mainEntity": [ { "@type": "Question", "name": "What is the path length of these cuvettes?", "acceptedAnswer": { "@type": "Answer", "text": "Each cuvette provides a fixed 10 mm path length, the standard geometry for most benchtop UV-Vis spectrophotometers and absorbance calculations." } }, { "@type": "Question", "name": "What spectral range are these cuvettes suitable for?", "acceptedAnswer": { "@type": "Answer", "text": "The optical-grade plastic supports visible-range measurements and many near-UV applications.
