TEMS™ Technology

UDK Series Kjeldahl distillation units work with the innovative TEMS™ benefits, for unmatched savings.

Time Saving: rapid heating reduces wasted time
Energy Saving: limited energy consumption thus cutting CO_² emissions
Money Saving: cost reduction for each analysis
Space Saving: the narrow footprint saves valuable laboratory bench space

Vreceiver™ boric acid with indicator sealed bags

VELP unique Vreceiver™ is a certified formula composed of Boric Acid powder and a mixture of indicators mentioned by AOAC methods (Bromocresol Green and Methyl red) allowing fast and standardized receiving solution preparation for colorimetric titration.

The receiving solution is prepared in a few minutes facilitating the day by day operations instead of the typical time consuming process using single reagents. The result is a reliable and standardized solution for colorimetric titration.

Barcode technology for smart operations

The optional barcode reader matched with the sample tubes with barcode (Code A00000144) simplifies distillation data management and result calculation.

The barcode on the tubes can be scanned in order to transfer the data automatically for an optimized analysis workflow.

Reduced risk of errors
Automated processes
Maximized efficiency
