SimPrep – Automated Liquid Handling Station

The SimPrep automated sample dilution system does more than just mixing and adding. It eliminates inconsistent manual dilutions, saves labor, and frees up personnel. With its simple, spreadsheet-like software, it is extremely user-friendly.

In addition to making dilutions, the SimPrep can perform the following tasks:

  • Spiking of samples
  • Preparation of calibration curves
  • Standard addition
  • Addition of internal standards


The SimPrep excels in accurately adding the desired amount at the designated position. It offers a wide range of syringes (10 µL to 50 mL), allowing you to customize the setup for optimal results across various applications. With this specialization, you can perform everything from dilution to dosing while staying within 1% of the target volume. Additionally, it achieves a carry-over of less than 0.01% through the integrated flushing program.

Standard addition – The software enables the user to add standard solutions for a variety of applications. Whether it’s a spike or a 1:1:10 dilution, the SimPrep makes it easy.

Programmable rinsing and mixing options make it easy to perform precise and straightforward serial dilutions.

The same sample can be prepared in different ways. This is perfect for customers who not only want to prepare for a single analysis.

The SimPrep can prepare the entire curve from a single stock solution, bringing a high level of precision and accuracy to the key preparation of the day. Auto-calibration data from a 6-point curve. Standards prepared from a 100 ppm stock solution in 10x to 2000x dilutions.

To ensure compatibility with various laboratory setups, the SimPrep system offers a wide range of syringes, ranging from 10 μL to 50 mL. This flexibility allows you to handle samples of different volumes with ease and precision. Additionally, the system provides seamless integration with an extra autosampler, enabling you to effortlessly switch between sample preparation and sample analysis. This convenient feature is made possible by a switching USB hub, ensuring a smooth transition between the two processes.

When using the SimPrep system, you can expect outstanding results. The system enables homogenous dilutions up to 2000x, minimizing any potential inconsistencies. Carryover is kept below 0.01%, ensuring the accuracy of your analyses. Precision is maintained at approximately 0.8% RSD for 10x 1:10 sample dilutions, while accuracy ranges from 95% to 105% for 50 μg/L CCV standard runs conducted every 10 samples. The linearity of the system is exceptional, with an r² value exceeding 0.999.
