All advantages at a glance

Optimal dosing of different sample types

The HP-GVD gravimetric vibratory dosing system enables the flexible and accurate dosing of a wide range of different sample materials. The HP-GVD can be used for a wide range of various applications, e.g. in steel, mining, food, and environmental analysis. The HP-GVD is used for dosing sample material into different crucibles and containers, but also into deep well plates. The vibration strength of the HP-GVD is continuously adjusted to the difference to the target weight and the change in weight. This enables a precise but also fast achievement of the required weight. 

Maximum flexibility for numerous applications

The HP-GVD can be optimally configured for each application. The width, depth and length of the vibrating feeder can be adapted to the sample volume. In addition, different surface coatings are available, and barriers can be installed to retain larger particles or to achieve a more even material flow into the target vessel. The HP-GVD usually enables both forward and backward transport of the material on the chute. By retracting the material, it can be ensured that no contamination of surrounding vessels or surfaces by the sample on the vibratory feeder takes place after the dosing process has been completed. 

Effective mechanisms to prevent contamination

If required, the vibratory chute of the HP-GVD can be cleaned using various mechanisms. This can be done using compressed air or mechanical cleaning, or residual particles can be extracted by vacuum, as is the case with chip dosing in the CNS Lab. For highly sensitive analysis methods using PCR or ICP, a special cleaning unit can also be used for wet cleaning and heating of the dosing chute to denature DNA residues.
