Avid Nano has released a report that demonstrates how its Bladecell disposable cuvette improves dynamic light scattering (DLS) sample preparation time compared with using traditional quartz cuvettes.
The company said the 5ul Bladecell cuvette combines the convenience of a disposable sample holder with the measurement quality of a quartz cuvette.
Precision moulded in black polycarbonate, the Bladecell requires no sample preparation beyond centrifuging to reduce the possibility of dust contamination that can affect DLS measurements.
To fill, 5ul of sample is pipetted against the walls of the Bladecell liquid trap where it is retained by surface tension.
The prepared cuvette is placed into the temperature-controlled sample holder of the Avid Nano W130I, where it can be analysed by DLS in seconds.
After analysis, the sample is recovered by dipping a pipette tip into the liquid trap and removing the contents.
As a low-cost cuvette, Avid Nano said the Bladecell can now be disposed of, eliminating the cleaning steps required when using more costly quartz cuvettes.
