Request InfoTesta Analytical Solutions eKBERLIN, April 9, 2021 — The HK Series Differential Refractometer from Testa Analytical Solutions eK uses light scattering techniques to provide precise determination of specific refractive index increment for polymer and protein molecular weight determination. The refractometer is a flexible device that may be used in either static or dynamic mode. In static mode, the specific refractive index (dn/dc) of dissolved samples can be easily and precisely determined in just a few minutes. The system offers a large number of wavelength options, enabling precise matching of a user’s light scattering detector...See full productRelated content from Photonics MediaPRODUCTSBioPhotonics May/Jun 2023 IssueBeam ShaperThe πShaper 12_12_2.05_HP from AdlOptica Optical Systems GmbH is a beam shaper for high-power 2-µm lasers.
