Belec Vario Lab - Stationary OE spectrometer

Vario 1

The Belec Vario Lab is an all-rounder. The instrument combines a number of unique features. It is worth to have a closer look at it and to find out, whether the Belec Vario Lab is the best solution for your requirements.


  • highest analysis accuracy
  • maximum measuring value stability
  • can be adjusted to almost any kind of problem
  • low detection limits
  • robust laboratory spectrometer
  • flexibility through manifold equipment possibilities
  • free accessible sparking stand for bigger samples
  • installation and instruction by qualified personnel
  • base-specific recalibration samples inclusive


The Belec Vario Lab belongs to the most powerful spectrometers of its kind. Due to a simple operating interface and Software Belec WIN 21 it is no problem to operate the machine by one person only.The fields of application are most different. Whether in the laboratory or workshop – there is almost no place that can’t be considerated.

Ideal Working Conditions

The lower cabinet of the Belec Vario Lab serves for safe set-up of the spectrometer in a comfortable working hight. Furthermore, useful working material can be situated in the integrated lower.Get your Belec Vario Lab in the most different versions: as inertgas-, vacuum-breathed or even air spectrometer.

Additional Sparking Stand keeps up Versatility

An additional sparking table is recommendable, if you will analyse e.g. samples of different bases with a low melting point. An alternative sparking stand can keep the versatility of the instrument. While one of the sparking stands has to be cleaned before reusing it, the other one is fully available at the same time. This offers an additional assistance and saving of time to the operator.

Universally Applicable

A sparking probe can expand the function of the instrument, additionally. For the analysis of big, bulky or indestructible samples, you can use one of our sparking probes. Like this, the Belec Vario Lab covers most fields of activity and can be a reliable companion for different applications.

Sparking Probes

Choose between three different types of sparking probes according to your needs. The special Belec probe connector permits a very fast exchange of the different probes. Therefore, the small instrument grants a high versatility.

Vario Argon probeAt Belec we produce handy sparking probes which are convincing because of its high measuring accuracy. In addition to other elements, the carbon content can be exactly analysed. By using a special optical procedure, measurements lower than 0,1 %C can be attained with the same accuracy as those achieved by special carbon analyzers.


  • argon-flushed sparking probe
  • high measuring accuracy, incl. C
  • non-destructive testing
  • multi fibre quarz optics, 3m and 5m length
  • special probe connector system
  • lightweight shockproof plasic probe housing
  • adequate adapters available

Vario Argon probe UVThe Argon Probe UV allows the analysis of phosphorus and sulphur also with the Belec Compact Port. The short wavelengths emitted by these elements can not be transmitted by an optical fibre, unlike carbon. Instead, a small spectrometer is built into the probe. At the same time, it keeps its easy and comfortable handling due to low weight.


  • argon-flushed sparking probe
  • small spectrometer inside of the sparking probe
  • high measuring accuracy, incl. P and S
  • non-destructive testing
  • multi fibre quarz optics, 3m and 5m length
  • special probe connector system
  • lightweight shockproof plasic probe housing
  • adequate adapters available


Vario Air probeThe air probe comes into operation for quick mix-up checking. Inspection cycles of less than three seconds can be achieved, after which an approximate analysis and grade identification is displayed. If a mix is found, a visual and/or audible fault signal is generated, which must be confirmed by the operator.


  • air measurings
  • quick mix-up testing
  • multi fibre quarz optics, 3m and 5m length
  • special probe connector system
  • lightweight shockproof plastic probe housing
  • visual signal on mix-up testing incl. confirmation button
  • adequate adapters available


Belec offers a wide range of adapters for nearly every sample shape and size. Without a special sample preparation, various pieces such as pipes, wires from 0.5 mm, metal splinters, screws and even small balls can be analysed. Inform yourself about our special adapters for wires, tubes and small parts. Additionally, our application engineers are happy to provide solutions for your specific tasks.

IS Adapter wireThe Belec Vario Lab has got a sparking stand as bearing area for the sample to be analysed. In case that by sample size and shape the opening of the argon-flushed measuring chamber is not covered, there are suitable adapters available. They ensure the best possible analysis accuracy. With the centering prism, the corresponding adapters can be fixed on the sparking stand.With our set of wire adapters you can analyse wires of a diameter from 2mm to 12mm in intervals of 0,5mm. Here, wires are clamped into the adapter vertically. The centering prism fixes the adapter at the sparking stand to grant an optimum testing situation.Small wires up to a diameter of 0,5mm or from 0,5mm to 2mm diameter can be analysed with the help of adapters. The wires are clamped in horizontally and can be tested without problems.
IS Adapter tube 1Tube adapters with standardized outside diameter are available in different sizes. The different adapters can easily be replaced and therefore offer maximum flexibility to the operator. 
IS Adapter Small PartsThe special small part adapter can be used e.g. for the analysis of globes. By the use of a special vacuum system for sample fixing inside of the adapter, even a reliable small part analysis is possible.The special sparking table suits for the most different applications. Small parts with a minimum diameter of 4mm can be analysed by the use of special inserts. A very robust ceramic insert is used for samples of small cross-sections.For instruments with several bases, we recommend e.g. the sparking stand with stainless steel insert. By use of the insert, the memory-effect can be reduced.
