LS Instruments DWS RheoLab III Contact-Free DWS Rheometer for Viscoelasticity & Particle Sizing

The LS Instruments DWS RheoLab III is an advanced contact-free microrheometer utilizing the Diffusing Wave Spectroscopy (DWS) principle to measure viscoelastic properties and particle sizing of soft and turbid materials. This instrument supports small sample volumes (150 μL to 1.5 mL) within sealed cuvettes, minimizing sample consumption and avoiding sample deformation due to mechanical contact. It operates across a wide viscosity range (0.1 mPa·s to 1000 Pa·s) and an ultra-broad frequency range (0.01 to 10⁵ rad/s), enabling analysis of complex fluids, gels, polymers, emulsions, and biological materials.

Key technical features include:

This rheometer is widely adopted in biotechnology research, supporting molecular cloning workflows and synthetic biology experiments where minimal sample disturbance and precise rheological characterization are essential. Its performance is validated with rigorous calibration and tested for DWS measurement accuracy, sizing capability, and backscattering response.

The DWS RheoLab III package includes the instrument itself, a computer loaded with LSLab software, and all necessary power and communication cables. Technical sales consultation, on-site or remote training, and warranty support complement the purchase, ensuring confidence for researchers in academic, clinical, and industrial laboratories specializing in biopharmaceutical production pipelines and complex fluid characterization.

This device is critical in applications like live-cell imaging preparations, formulation development, quality control of soft materials, and detailed fluorescence analysis of biological gels and suspensions — all essential in cutting-edge biomanufacturing and molecular diagnostics research.
