High quality fruit fly food with an anti-mould agent in 10cm glass specimen tubes. Each ready-made media vial comes with both a plastic lid and cotton wool stopper (non-recyclable reusable foam bung option also available).
To ensure freshness, all media tubes are prepared to order at our lab in Shropshire and dispatched each Monday (the same day as the drosophila). Tubes are sent with a fitted plastic lid to increase the longevity of the media, once flies have been added, replace lid with cotton wool stopper or foam bung to allow air exchange. We recommend storing in the fridge until use and adding the flies within 1 week of receipt.
After use, the glass tubes can be reused and the cotton wool stopper composted.
We used to send our media tubes with a small sachet of yeast and plastic ladders however we no longer do so. This is because the media itself contains plenty of yeast to aid fermentation (fruit flies like 'off' foods) and the ladders have now been proven to be unnecessary as well as contributing to plastic waste. If you do still with to use yeast and ladders these can be purchased separately.
