The Eppendorf UVette allows for measurements in the UV/Vis range with transparency from 220 nm to 1,600 nm with just a typical minimum volume of 50 µL. The UVette allows the user to choose between two optical path lengths (10 mm and 2 mm). The path length can be reduced by a factor of x5 without diluting or wasting any sample – simply by turning the UVette 90°. The UVette is suitable for fluorescence assays due to its low auto-fluorescence. The PCR-clean and protein-free individually sealed variant is ideal for accurate nucleic acid and protein quantification. The UVette is ideally matched for use with the Eppendorf BioPhotometer and Eppendorf BioSpectrometer families. The UVette can be used in other spectrophotometers with the aid of an adapter.
The UVettes are manufactured from crystal clear plastic, which is UV/Vis transparent and features translucency between 220 nm and 1,600 nm. The openly accessible side walls allow for a visual check of the liquid inside the UVette from all sides. This enables the user to detect air bubbles, for example, which may alter the test result. Furthermore, the funnel–shaped design of the cuvette base prevents a capillary effect and ensures that even the minimum volume of 50 µL constantly remains centered in the measuring area.
Two packaging sizes and purity grades are available:
› The individually packaged UVettes are PCR-clean & protein-free and are the ideal choice for valuable samples. Samples can be recovered for downstream applications without the risk of degradation or contamination. Lot specific certificates are available on the Eppendorf webpage.
› The routine pack contains UVettes with Eppendorf certified quality and is the ideal choice for routine applications where many samples need to be screened. It offers safe storage in a reclosable box and convenient access to each cuvette which makes filling easy.
For safe handling, cuvettes should be handled in combination with specific cuvette holders.
