# Experiment Start

{% hint style="warning" %}
[Calibrate](/evolver/getting-started/calibrations.md) your eVOLVER before beginning your experiment
{% endhint %}

When starting an experiment you'll go through the same process as a [normal experiment](/evolver/experiments/starting-an-experiment.md). Make sure that you have the extractor columns properly set up and that you also include the slow pumps lines in your line sterilization process.

{% hint style="info" %}
Preemptively check the troubleshooting [page](broken://pages/iInKHmvhYMTeaE5seoyJ) to see common mistakes before running the experiment
