Rapid particle measurement in microplate format

Labsystems introduces the first-ever nephelometer for measuring particles in microplate format. Depending on the measurement type, a 96-well plate can be read in just 25 seconds.

Nepheloskan Ascent allows convenient testing of particles in microplate format for applications such as drug solubility tests, quantitation of specific proteins and antibiotic sensitivity studies.

Advanced light scattering optical system

Nepheloskan Ascent’s ultra-sensitive optical system produces a highly focused light beam that measures the scattering function of particles suspended in a medium at one angle. The data obtained is used to determine the particles as well as the precipitation that produces the cloudiness of the medium.

A highly focused light beam of 2 mm in diameter is produced by a light source below the microplate and an optical unit that filters and directs the light through the sample (3). Another optical unit only allows the scattered light (at about a 30° angle) to pass towards the detector, which is a photomultiplier tube above the microplate.

Adjustable orbital shaker and incubator – optional dispenser
system

The adjustable orbital shaker and incubator provide an added advantage for studies of factors affecting the solubility of pharmaceutical components as well as bacterial growth.

The optional dispensing system also provides a convenient way to kinetically study the formation of immunocomplexes in a liquid form, for example. With them highly visual Ascent Software, the real-time kinetic curves of the assay can be followed.
