Fluorimetry Cuvettes

NEW! Disposable macro cuvettes with 4 optically clear sides from BRAND suitable for use in fluorescence 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.

Frequently Asked Questions

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

2. 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.

3. 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.

4. 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.

WARNING These products can expose you to chemicals including Di (2-ethylhexyl)phthalate (DEHP), which is known to the State of California to cause cancer and birth defects or other reproductive harm, -Methyl styrene (alpha-Methylstyrene), which is known to the State of California to cause cancer, and Di-n-butyl Phthalate (DBP), which is known to the State of California to cause birth defects or other reproductive harm.
