BrandTech, 759076D, 1.5 - 3ml Semi-Micro Polystyrene Cuvette (Pack of 100)BRAND's plastic cuvettes are manufactufrom the highest quality virgin resins for highest optical quality and are an excellent choice for most spectrophotometry applications in the visible range. Manufactufrom polystyrene (PS) or polymethyl methacrylate (PMMA), they provide accurate, reliable results. Choose PS for determinations above 340nm, and where cost is a concern. When performing assays above 300nm, choose PMMA. (For wavelengths below 300nm, see our UV-cuvettes). These disposable cuvettes are available in macro and semi-micro sizes to accommodate most sample volumes and are compatible with most spectrophotometers and photometers. All BRAND cuvettes are manufactufrom scratch-resistant materials, and are grouped by manufacturing mold cavity number to ensure the lowest variation in extinction coefficient.BRAND is world-renowned as the producer of premium disposable cuvettes. Each and every BRAND cuvette benefits from their over twenty five years of experience manufacturing cuvettes to the most exacting standards for reproducible results.BRAND plastic cuvettes are an excellent choice for most spectrophotometry applications in the visible and near-UV range. When manufactufrom PS and PMMA, they provide accurate, reliable results even at wavelengths as low as 300nm. These disposable cuvettes are available in macro and semi-micro sizes to accommodate most sample volumes. BRAND plastic cuvettes are compatible with most spectrophotometers and photometers using a standard 10mm path length.FeaturesEasy to Use: BRAND plastic disposable cuvettes include an arrow mark to indicate direction of transmission and reduce variation.Options for Most Needs: PS and PMMA cuvettes are available in both macro and semi-micro sizes to adapt to the needs of most laboratory applications. Semi-micro cuvettes require only 1.5mL of sample volume to provide reliable, accurate results.Perform Consistently: Cuvettes are manufactufrom high-quality materials, and are grouped by manufacturing mold cavity number to ensure the lowest variation in extinction coefficient.Manufactuby BRAND: One of the world's largest producers of cuvettes, BRAND's over twenty-five years of quality cuvette manufacturing experience is your assurance of reliability.Mold-Cavity Matching:All plastic cuvettes are manufactuin multicavity molds, producing multiple cuvettes with each molding operation. Even with BRAND's experience and attention to manufacturing detail, nothing can prevent slight differences among the cavities that can lead to variation in extinction coefficients. Rather than randomly aggregate cuvettes from all cavities, BRAND's automated production process sorts the cuvettes by mold cavity; each package only contains cuvettes from the same mold cavity. This ensures the lowest possible cuvette-to-cuvette variance, and more accurate measurements. Robotic sorting also eliminates the risk of human error, and potential contamination.Protective Packaging: BRAND cuvettes are encased in dust-free, lowscratching expanded polystyrene packaging. This ensures that your premium cuvettes arrive at your laboratory in the same pristine condition they were in at the factory, with optical quality windows, and free of contaminants. For applications in which the highest purity is required, BRAND ultra-micro UV-Cuvettes are available individually wrapped and free of DNA, DNase and RNase. Individual wrapping means that these cuvettes offer not only the convenience of disposability, but a degree of sample protection that is unmatched by any reusable cuvette.Unit of MeasurePack of 100 pcs.
