Quick release lid for 10L swim tunnel

This optional extra lid allows for quick and easy access to the downstream portion of the swim tunnel test section. When force-swimming groups of smaller fish (e.g., zebrafish), this quick release lid will help you get fatigued specimens out in no time and without disturbing the rest of the fish or having to stop the experiment. The lid opening is placed right next to the downstream grid, where fatigued fish tend to end up during swimming performance tests. This means that if one or multiple animals get stuck on the grid during swimming, the animals can be quickly removed without having to unscrew the larger lid covering the whole test section.
