BRAND Fluorimetry Cuvettes, PS, 500 Pack

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.

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.

Frequently Asked Questions

What is the light path of the BRAND cuvettes?  All BRAND cuvettes have a light path of 10mm.

What is the difference between the PS and UV-Cuvettes?  Polystyrene (PS) cuvettes are the least expensive, however they have the lowest chemical resistance, and are only suitable for visible light applications, with a lower wavelength limit of around 340nm. BRAND UV-Cuvettes use a proprietary plastic to allow measurement as low as 230nm, and has resistance to many polar organics as well as many acids and bases. The UV-cuvettes also show no autofluorescence.

What does "mold cavity matched" mean?  Cuvettes are injection molded plastic. No matter how close the tolerances are in the molds, there will be some variance. BRAND cuvettes are sorted during the manufacturing process so that each package of cuvettes contains only cuvettes made from the same mold, minimizing the cuvette-to-cuvette variance.

What is the maximum temperature the PS and UV-cuvettes can tolerate?  Both the PS and UV-cuvettes should not be used at temperatures above 70°C.
