DynaPro Plate Reader II

DynaPro Plate Reader II


High-throughput, automated, temperature-controlled Dynamic Light Scattering.

Revolutionize your performance by replacing your conventional, cuvette-based dynamic light scattering unit with the automated DynaPro® Plate Reader II. The DynaPro excels at high-throughput sizing and screening of pharmaceutical and nanoparticle formulations to enable novel workflows that simply would not be possible with other DLS instruments. Even if you need to run just a handful of samples, it's a great productivity booster.

Included with each DynaPro Plate Reader is a copy of DYNAMICS, our powerful software package for analyzing automated batch dynamic light scattering. The Security Pack (DYNAMICS SP) option provides 21 CFR (11) compliance for GMP/GLP use.

  • Revolutionize DLS

    The DynaPro Plate Reader II offers dynamic light scattering (DLS) measurements of the size and interactions of proteins, nanoparticles and other macromolecules in situ in industry-standard microwell plates. No liquid handling occurs after dispensing into the plates, to maximize throughput and minimize sample carryover. This ground-breaking instrument provides rapid optimization of the formulation process for:

    Key features

    • Measure hydrodynamic radius from 0.5 nm to 1000 nm
    • Sensitivity down to 0.125 mg/mL lysozyme
    • Industry standard microwell plates of 96, 384 or 1536 wells
    • All measurements made in situ in the wells
    • Temperature ramps from 4°C to 85°C
    • Integrates with plate-based liquid handling robotics

    A wealth of applications

    The DynaPro Plate Reader II provides unparalleled levels of ease-of-use, productivity, reproducibility, and flexibility in order to address additional demanding applications such as:

    • Optimizing protein crystallization
    • Assessing aggregation or oligomerization
    • Determining protein stability-indicating parameters such as thermal denaturation and colloidal stability
    • Screening high-concentration protein solutions for reversible association and viscosity

    • A wealth of features

      • Rapid or slow temperature ramps 4°C - 85°C with excellent uniformity across the plates. Samples are heated in parallel and all filled wells measured at each temperature
      • Well read times as short as 5-10 seconds
      • Integration with liquid-handling robots for higher levels of automation, especially when your workflow is plate-based, and utilizes spectroscopic and other plate readers in addition to DLS
      • A camera for viewing each well from below, to aid in data diagnostics (e.g. to detect precipitation or bubble formation)
    • A set of images collected by the onboard camera, showing clean wells and wells containing bubbles, crystals and precipitates.

    • Lab automation

      An OLE software API is available for interfacing the DynaPro Plate Reader II to robotic liquid handling in the high-throughput lab. This capability allows for fully automated plate loading and data collection.
