ETA2010 Differential Viscometer

The ETA2010 differential viscosity detector is designed to meet the requirements of modern GPC applications. Low-noise electronics combined with high-sensitivity pressure transducers as well as superior sample path design results in an excellent detection limit and high signal linearity. The instrument was designed for ease-of-use and trouble-free operation.


Refractometer for dn/dc

The Differential Refractometer Dndc2010 accurately measures the specific refractive index increment value (dn/dc) required for any light scattering analysis or the determination of polymer parameters. Available for either on-line or off-line measurements these instruments are the perfect, affordable “must” in modern laboratories for many reasons.


Multi Angle Light Scattering Photometer SLD7000

Characterizing dilute macromolecular solutions using static light scattering (SLS) has never been easier, more accurate, or a better value. The SLD7000 Multi-angle Light Scattering Photometer uses latest technological achievements in optics and electronics to ensure easy and reliable operation in all laboratories. The SLD7000 can be used stand-alone or as a LC detector.

GPC/SEC Columns

Gel Permeation Chromatography (GPC), Size Exclusion Chromatography (SEC), or Gel Filtration Chromatography (GFC) are names used interchangeably for a liquid chromatography technique to obtain separation according to molecular dimensions. Contrary to LAC- (Liquid Adsorption Chromatography) methods like HPLC, that rely on interactions between sample and stationary phase (column material), GPC/SEC must operate free of interactions.
