Belec - Model Vario Lab -Laboratory Spectrometer
Belec has entirely re-designed the well established laboratory spectrometer. The Belec Vario Lab again sets a unique standard in terms of precision and flexibility as it has been continuously improved in order to fulfill today’s needs for metal analysis. It is – again- the most competitive in terms of flexibility as far as sample size and shape is concerned. Next to the fixed sparking stand it can be equipped with an additional sparking probe.
