Automated Sample Preparation Systems

prepMASS Station – Gravimetric Dilution

prepMASS fully automates by-weight dilution for oil and lubricant samples, providing high-throughput processing and eliminating manual preparation.

Accurate. Automated. Amazing.

prepMASS is an automated sample preparation system for lubricants consisting of an intelligent sample handling system and a syringe pump coupled with an integrated balance. The system delivers:

  • Precise and accurate by-weight dilutions of oils and lubricant samples
  • Accounts for differences in sample density by dilution according to measured mass
  • Eliminates all manual sample dilutions, saving valuable laboratory time and eliminating errors

Ease of Use

prepMASS provides laboratories with complete automation for preparing oil and lubricant samples for ICP/ICPMS analysis. The system places an empty vial on the balance and immediately tares it. The lubricant sample is then precisely measured by weight while being delivered into the vial. Finally, the diluent is added by weight to the desired dilution factor. prepMASS takes the guesswork out of gravimetric dilutions with:

  • Simple, intuitive software interface that provides for walk-up use
  • Each step in the dilution process is recorded
  • Each data set is saved and easily exportable to LIMS
  • Disposable pipette tips eliminate sample carryover
  • Commonly used dilution protocols can be saved for routine usage
