Easy to use

The VariRef combines proven SCHMIDT + HAENSCH technology with the modularity of the VariFamily. The new double isolated peltier systems allows fast temperature control and reduces the influence of environment temperature, resulting in rapid and precise measurements.

The VariRef has the well-established SCHMIDT + HAENSCH sample chamber. Its flat shape is ideal for easy cleaning. Different sample chamber covers for liquids and solid samples makes it possible to adapt the device to your application. When dealing with hard-to-clean or hazardous materials we offer a special covered version to ensure a long and reliable product lifespan.

Applications

SCHMIDT + HAENSCH refractometers can be used for purity investigations, sample recognition, dilution control or composition. They are also used for characterization of substances or for determination of substance composition, especially of organic liquids or raw materials. With different sample chamber compartment doors it is also possible to measure solid samples which makes it also suitable for other applications, such as quality control of optical films, glass or fibers. Refractometers are also widely used in food, oil, fuel, and other industries to measure and monitor the concentration of components throughout the fabrication process.

XRF (G SERIES) – BOWMAN

The G Series XRF is an ideal choice for laboratories and production lines, especially for users with limited workspace, budget constraints, or a preference for "bottom to top" operation with motorized Z-axis control. Designed to efficiently analyze small samples quickly and easily, this system offers flexibility and high performance in material inspection and evaluation.

MICRO XRF (W SERIES)- BOWMAN

The W Series Micro XRF from Bowman features a 7.5 µm FWHM X-ray beam, the smallest in the world for coating thickness analysis using XRF technology. This makes it ideal for measuring small components like BGAs and solder bumps. It includes a dual-camera system with 140X magnification for precision imaging and a secondary camera for live viewing. A programmable X-Y stage with ±1 µm accuracy, along with pattern recognition and auto-focus, enables precise measurements and automated multi-point analysis. The system also offers 3D mapping for coating topography visualization. Standard configurations include a molybdenum anode tube (with optional chromium or tungsten) and a high-resolution Silicon Drift Detector. The instrument can measure up to five coating layers simultaneously and operates with Archer software, which streamlines measurement, reporting, and application setup.
