Automated Sample Digestion System- Nitron

Nitron does High-Temperature Automated Sample Digestion and Dispensing for laboratories. It is designed for routine and customizable methods that require heating up to 400°C. Hence it is ideal for automating applications involving acids like sulphuric and phosphoric acid. The six independent reagent lines reduce priming operations, thus increasing dispensing speed and minimizing cross contamination. Nitron has an all-plastic fume hood, thus providing a safe environment by reducing user contact with harmful acid fumes and hot samples.


Automated Dilution System – QPrep

The QPrep Automated Workstation provides an integrated solution for precise sample dilutions, transfers, dispensing and other liquid handling functions for the laboratory. The system is designed to handle precise reagent delivery for a large number of samples in multiple rack configurations. Automating the handling of expensive and hazardous chemicals helps to increase the profitability and safety of the laboratory.

Features :
  • Spikes sample with internal standards
  • Performs Multiple Dilutions
  • Prepares calibration and QC standards
  • Serial dilutions and aliquot transfers
