About Us

MolmeX Scientific, Inc. is a distributor of specialized scientific instrumentation with a high level of expertise and long history in the development of commercial Small Angle X-ray Scattering (SAXS). Our goal is simply to offer the best customer-specific solutions, whether complete systems, or components like source, optics, slits and detectors.

Molmex provides installation and service for its product line and an appropriate level of customization so customers can meet their experimental challenges. Under the SAXSLAB label, Molmex manufactures its own Ultra Small Angle Scattering (USAXS) instruments.

Our Services

We take pride in all aspects of the process from discussing the various options with you, to installing and providing service and maintenance.

  • Consulting

    We’ll evaluate your project and help you find the best products to fit your needs.

  • Manufacturing

    We are co-located and share resources with SAXSLAB US, the designer and manufacturer of probably the best laboratory SAXS system.

  • Distribution

    We are the North America distributor for SAXSLAB, LS Instruments, Dectris and JJ X-RAY.

  • Support

    In addition to delivering and installing your system, we provide training, support and maintenance.

Unique Solutions

Each project is different and every lab is unique. We can supply a new turn-key SAXS instrument, or upgrade your existing system with new components. We’ll evaluate your needs and provide you with the exact setup you require, including any customizations and support to get you up and running. Here are a few of the technologies we offer:

SAXSLAB Small Angle X-Ray Scattering (SAXS)

SAXLAB designs and manufactures the Ganesha line of laboratory SAXS instruments, used in top laboratories in the US and Europe. This product is distinguished by the moving detector in vacuum for automated sampling continuously from WAXS to SAXS, variable size pinhole geometry, and total automation including alignment. For probing larger d-spacings up to 5 microns, SAXSLAB provides the USAXS from Molmex Scientific.  View SAXSLAB’s website


  • Total turnkey automation of 2D scattering from WAXS to SAXS
  • Moving Detector in vacuum
  • Automated alignment and resolution with scatterless slits

Sol Wizard

  • Dedicated Protein solution scattering with moving detector in vacuum
  • Pipetting robot with 5 microliters delivery and position feedback
  • Highest brilliance Metaljet source available


  • Resolution up to 5 microns
  • Cu and Moly available in one package
  • Dectris linear or area detector

LS Instruments Advanced Static and Dynamic Light Scattering

LS Instruments provides the most advanced and technically up-to-date instrumentation for static and dynamic light scattering. Their products are born in the research lab out of necessity, then developed into robust, user-friendly commercial tools for basic science and industry. Using their novel approach to 3D cross-correlation light scattering, particle sizing and dynamics can be determined in turbid solutions with high signal-to-noise. Diffusing Wave Scattering (DWS) provides particle sizing in opaque samples and DWS Microrheology extends the time-dependent modulus to higher frequencies than mechanical techniques.  View LS Instruments’ website

  • 3D Cross-Correlated Dynamic Light Scattering (3D DLS)
  • Optical Microrheology using Diffusing Wave Scattering (DWS)
  • Static Light Scattering with DLS at multiple q vectors

Dectris 2D and 1D X-Ray detectors

Dectris supplies the latest detector technology for synchrotron radiation and laboratory scattering. Recognized as the leader in the field of hybrid pixel technology, they have changed the landscape of x-ray scattering science by making robust 2D and 1D detectors available in a wide variety of formats and count rate capabilities.  View Dectris’ website

  • Affordable world class solutions for laboratory upgrades
  • Imaging applications
  • SR detectors with the highest count rate capability and custom solutions

JJ X-RAY Custom beam line solutions

JJXRAY designs, manufactures extremely durable, precision instruments targeting the analytical x-ray, synchrotron radiation and neutron research communities. While slits systems are the most well-known product in the JJXRAY portfolio, they are fast becoming recognized for their custom beamline components, including the Large Offset Double Crystal Monchromator (LODCM) at the Linear Coherent Light Source (LCLS) at SLAC, and the FXE beamline at the European X-ray Free Electron Laser (XFEL).  View JJ X-RAY’s website

  • “JJ” Slits for SR and laboratory applications
  • Compound Refractive Lenses (CRLs) for beam lines
  • Total beamline solutions.
