EasyChem Jr

Multi-Parameter Discrete Analyzer

The EasyChem Jr is a compact discrete analyzer designed for labs that need to increase productivity and minimize costs while analyzing water, soil and plant tissue.

  • 10 or 20 sample capacity

  • Up to 150 tests per hour

  • Test each sample for multiple parameters

  • Fully automated - Simply program your worklist and walk away.

  • Export Results to Excel, LIMS or shared drive

  • Easy to use - No scientific background required

Easy Operation

Daily operation of the EasyChem Jr. is simple. Worklists can be programmed in fewer than five minutes.


Simply enter the sample information and select which chemistries are to be performed.


Press play and the EasyChem Jr will run unattended for up to 720 tests.

Highly Automated

The EasyChem Jr offers a highly automated solution that allows operators to program their daily worklist and then leave the instrument to run unattended as they perform other duties around the laboratory.

  • Start up and Shut Down

  • Calibration Curves

  • Pre or Post Dilutions

  • QC checks

  • Weight and Moisture Corrrections

  • Reagent and Instrument Monitoring

  • Data export

Automated Calibration


Calibration curves can be automatically generated from a known standard.


All calibration information is automatically saved for traceability and can be exported into reports for auditing purposes.
