Belec Vario Lab

Flexibility and Precision Combined

Belec has completely redesigned the laboratory spectrometer for metal analysis. It is – again- the  most competitive in terms of flexibility as far as sample size and shape is concerned. 

The Belec Vario Lab can optionally be equipped with a connectable sparking probe.

Thanks to a more powerful plasma generator and lower argon consumption, operating costs are significantly reduced while the analysis times per sample are shortened. The new argon control system for the sparking stand surprisingly minimizes maintenance requirements a lot. 

The Belec Vario Lab impresses with its exceptional performance! 

The compact design allows for transport through standard doors, and the high-stability plastic housing significantly reduces weight. The integrated and dynamic material database is standard, as it has been for ever since in all Belec spectrometers. This ensures automatic material identification with every analysis. The grade database can unlimited be extended with national and international grades and can certainly also be customized.

      The Belec Vario Lab is one of the most powerful spectrometers of its kind.

      Thanks to a simple operating interface and Software Belec WIN 21 there are virtually no limitations. Any program feature can easily be selected and configured according to customer specific applications.

      The fields of application are not limited. Whether in the laboratory or workshop – there is no location that can not be considered.

      Ideal Working Conditions

      The attractive design of the Belec Vario Lab ensures an ergonomic set-up of the spectrometer at a comfortable working height. The drawer has enough space to accommodate user tools, drift correction samples and other accessories.

      Get your Belec Vario Lab in the different versions: as inert gas- breathed, vacuum-operated or even air spectrometer, depending on the application.

      Two Models to select,
      depending on your needs

      The variation, Model 2P, equipped with the traditional, highly sensitive Photomultiplier detectors, is the ideal tool whenever maximum precision, accuracy and low limit of detection are essentially required.

      The second variation, the Model 2C, is equipped with the latest-state-of art CCD detectors.
      Due to the flexible design it is recommended for any multi-base application.

      The well established 6GSO system, already used in other belec spectrometers ensures the uncompromising use of ideal spectral lines.

      The need for daily recalibration is a thing of the past due to the MCDC system which automatically corrects spectral line drift.

      Universally Applicable with additional Probe

      An additional Sparking Probe can further enhance the functionality of the instrument.

      For the analysis of big, bulky or indestructible samples, you can use one of our sparking probes. With this unique option, the Belec Vario Lab covers all possible applications for metal analysis.

      Accessories of Belec Vario Lab

      Belec offers a number of accessories, both for mobile use at different places and localized use of the stationary instruments.  

      Whether sparking probes for mobile use with the Belec Compact Port HLC or in addition to the sparking table of the Belec Vario Lab - get to know more about our additional solutions for your individual requirements. 

      A number of adapters allow the testing of most different sample types as wires, tubes or other small parts. Due to especially developed adapters they can be analysed without any problems.

      Furthermore, we offer our customers other solutions which exactly match with their applications.
