Add-ons for DanioVision

DanioVision is a complete system, including the Observation Chamber, with white light, IR-light, IR-sensitive camera, etc. It also includes a fully functional EthoVision XT license. This system is suitable for a large range of experiments. However, you might want more.

We offer a range of add-ons to further broaden the experimental options with DanioVision. The currently available add-ons are listed on this page. Most add-ons can be controlled with EthoVision XT.

Temperature control

Temperature is an important element in zebrafish research, having a large impact on health, but also on mobility and other parameters. Sometimes, especially during relatively longer trials, it can be tricky to keep the environmental temperature of your zebrafish larvae at a constant.

Tapping Device

Instead of using a white light pulse, a startle response can also be evoked by “tapping” at the base of the well plate.

When studied in rodents, optogenetics require the implantation of optical fibers. However, because zebrafish larvae are transparent, you simply need to shine the correct color of light in the right direction.

The Optogenetics add-on for DanioVision does just that. Read more about it here.

Toplight Unit

Some studies require lighting from a more ‘natural position’ from above. This addition of the Toplight Unit to your DanioVision Observation Chamber gives you just that. It offers both white and colored lighting.

Read about why you need a Toplight Unit and what it offers here.

Light-dark grid

As research evolves, so do research needs. If you are interested in a custom solution, don’t hesitate to contact us now!

light-dark grid DanioVision

One recent example of a custom solution is a light-dark grid, commonly used to investigate anxiety behavior in zebrafish. The grid is placed underneath the well plate (available for 6, 12, 24, 48 or 96 wells) and creates a dark and light half in each well. The grid is IR light translucent, leaving the tracking of the zebrafish unaffected.
