The latest in automation technology saves hours every day

A six month trial of the latest generation Kjeltec solution revealed significant time savings for a busy industry laboratory. Learn more in this video interview.

Features

  • Unmatched accuracy with colorimetric titration

    Classical colorimetric titration is combined with unique technology such as automatic LED calibra­tion and automatic end-point colour to ensure that the results are always correct, and performance is stable over time.

     

    The automatic end-point colour feature in combination with auto mode ensures that each analysis is done in a reliable way as fast as possible. The new titration controller guarantees that the correct end-point is reached continuously throughout the distillation process.

  • Safe and easy operations

    Reduce the training and staffing burden typically associated with managing chemical analysis operations and stop worrying about safety procedures. Kjeltec 9 is easy to operate and provides new levels of automation to save operator time and ensure safety. The user is fully protected by the unique safety door which must be closed with a tube in place before the unit will operate. Reduce the risk of chemical spillage with FOSS pioneered SAfE* mode, smart filling of reagents and minimal cleaning and maintenance for the operator.

    *Steam Addition for Equilibration

  • Set up 'Alerts and Notifications' to avoid downtime

    Set up your Kjeltec 9 to provide staff with ‘real-time’ notifications in the case of errors. The optional service ‘Alerts and Notifications’ offers real-time notification of selected events such as an instrument or Autosampler error, via email or text message. This allows you to avoid downtime and let staff get on with other tasks while analysis is running.

  • Accurate results and easy data handling

    Easy data handling starts with registration and configuration of your sample batches. This data is transferred to your Kjeltec 9 Analyser using the optional Kjeltec Registration PC software. Simply scan the sample ID on incoming samples to register and configure sample batches and know which test programme to run.

  • New levels of integration with indirect methods

    One of the challenges faced by laboratories today is that incoming samples lack information regarding expected values for fat, protein, and moisture. Integrating indirect methods in the sample preparation phase takes the guesswork out of reference analysis. Screen samples with near infrared (NIR) or Fourier Transform Infrared (FTIR) to get an estimate on expected values and choose the reference method for your next step with confidence. Eliminate errors, avoid costly re-runs and reduce the use of chemicals to save time and money.

Kjeltec autosampler

Fully unattended operations with a Kjeltec™ 9 Autosampler

Increase laboratory throughput while reducing your training and staffing burden with an optional Kjeltec™ 9 Autosampler that allows you to test 20 or 60 samples at a time. With a 20 or 60 place Autosampler, batch handling is fully automated letting you run up to 240 samples in 24 hours. Just load your sample racks and the system runs unattended for more than four hours.
