Automation of sample preparation for analytics


  …our conviction that we are using the right products is stronger than ever. We have now optimized our workflow for dosing and pipetting and achieve a standard deviation of 0.2 % between 0.5 and 1 ml. If the ambient temperature can be kept constant the precision would presumably be even higher. (Dr. Schneider, CEO RPD Tool Technologies)


RPD Tool technologies is a Swiss company that offers a sophisticated tool for automation of analytical workflows in R&D, quality control, production, analytical and biological science.

The SamplePrep is the solution for automation of analytical sample preparation compatible with all standard Chromatography systems (UPLC, HPLC) and other analytical devices (IC, ICP/MS etc.). The flexibility of the system and the large number of available modules ensure that almost all types of sample preparation can be automated on a single platform. Liquid handling with 2-4 channels in a dosing range of 5 µl to 100 ml and a pipetting range of 5 µl to 10 ml can be integrated together with a lot of other options (sample grinding, solvent extraction, filtration, centrifugation, weighing, cooling and heating ). The standard deviation between 0.5 and 1 ml is as low as approx. 0.2 %.

Direct connection to chromatographic instruments or other analytical devices is possible. All steps of automated sample preparation are compliant to CFR21 part 11.
