Research Goniometer and Laser Light Scattering System

Reserve it!

The Bl-200SM Research Goniometer System provides access to all of these studies with an automatic,modular and versatile system. It is a precision instrument designed for exacting scattering measurements. Based on a special turntable with precision ball bearings and stepping motor, the Bl-200SM's modern design, and quality construction guarantee precise measurements due to the wobble-free movement of the detector. It is field proven in hundreds of laboratories. It is ideal for macro-molecular studies and submicron particle sizing.

Features:

  • Stepping motor controlled, multiangle measurements
  • Particle size and size distributions
  • Mw, Rg, A2 for dilute polymer solutions
  • Cross-correlation detector option
  • Avalanche photodiode detector option
  • CONTIN, Zimm, Guinier, Fractal, and more
