Fluorimetry Cuvettes
NEW! Disposable macro cuvettes with 4 optically clear sides from BRAND suitable for use in flourescence applications. Available in high quality polystyrene for measurements from 340nm to 800nm, as well as a proprietary polymer with ultra-low autofluorescence for precise measurements in both the visible and UV-range (230-800nm). Cuvettes have a standard 10mm light path for use in all standard fluorimeters. Packaging is 100 per tray in trays made of low-dust, non-scratching polystyrene, and are grouped by manufacturing mold cavity to ensure the lowest variation in extinction coefficient.
BRAND UV-Cuvettes are the disposable alternative to quartz cuvettes for applications that require UVtransparency. Unlike Polystyrene (PS) and Polymethyl methacrylate (PMMA or "acrylic") cuvettes, BRAND UV-Cuvettes are transparent down to 220 nm, so they are suited to molecular biology applications, such as A260/280 purity determinations and other analyses in the UV wavelength range. Besides their UV-transparency, this proprietary plastic is also more resistant to chemical attack than PS or PMMA, and so may bring disposability to applications in which disposable cuvettes were not previously an option because of limited compatibility.
When results count, choose BRAND disposable cuvettes with four optically clear sides for fluorescence applications. Available in high quality polystyrene for measurements from 340nm to 800nm, as well as a proprietary polymer for precise measurements in both the visible and UV-range (230-800nm), allowing for shorter excitation wavelength than have been traditionally possible with disposable cuvettes. This UV-transparent plastic also has virtually no autofluorescence for high signal-to-noise ratios. Cuvettes have a standard 10mm light path for use in all standard fluorimeters.
BRAND fluorescence cuvettes, like all BRAND cuvettes, are made of the highest quality raw materials, precision molded for the best optical clarity, with parallel walls of uniform thickness to optimize transmission and minimize refraction. They are then moldcavity sorted ensuring cuvette-to-cuvette consistency for highly reproducible results. With an industry standard 10mm light path, BRAND 4 sided clear cuvettes fit most common fluorometers. Cuvettes are packaged in trays containing 100 cuvettes. Trays are made of low-dust, non-scratching, expanded polystyrene.
Features:
- Mold-cavity sorted: Each tray contains cuvettes from a single mold cavity to minimize variability between cuvettes.
- Manufactured by BRAND: One of the leading manufacturers of premium quality disposable cuvettes for nearly thirty years, BRAND is your assurance of reliability.
