Abstract

The invention utilises liquid surface tension to provide a disposable sample cuvette 42 which includes the combination of low cost and low sample volume together with high quality measurement capabilities. Light scattering equipment 40, 41 can allow users to identify certain properties of solutions and suspensions including the hydrodynamic size of particles and molecules by either static or dynamic light scattering without altering the sample in an invasive way. The cuvette 42 utilizes a small hole of precise dimensions to retain a liquid sample such that a light scattering measurement can take place. By correcting for the effects of refraction and from the meniscus at the surface of the liquid sample, an accurate measurement can be obtained from as little as a 5 microlitre sample volume. The path length may be about 1mm and the cuvette body may partly consist of an opaque material allowing light to be shielded or screened to reduce reflections.
