Dynamic light scattering instrument Photocor Complex
(Laser Biospectroscopy Laboratory)

Dynamic light scattering instrument Photocor Complex Photocor instruments are based on the static and dynamic light scattering (photon correlation spectroscopy). This technique is ideal for measurements of nanoparticle size, diffusion coefficient, and molecular weight of polymers in solutions. A traditional design of the Photocor Complex is optimal for a wide range of applications: from simple industrial tests to the most advanced research tasks. Measurement procedure and powerful software are suitable for any level of users.

Features

  • Full-featured multi-angle dynamic and static light scattering, fast measurements, real-time size monitoring of nanoparticles
  • Traditional user-open modular architecture, rigid design, no optical table needed, easily configurable by user
  • Easy-to-prepare samples, suitable for various commercial sample cells and vials, replaceable index-matching vat system
  • Stepper-motor controlled turntable, compatibility with various lasers and PMT/APD photon counting systems
  • Precise thermostat with PID controller and provision for temperature control via external circulator/chiller
  • Unique flex-logic single-board correlator, linear and multiple-tau time scale, upgrade of hardware configurations
  • Original light-scattering geometry for particle sizing of opaque dispersions
  • Exceptional quality and reliability with all light scattering features for optimal price
