These vials are not autoclavable because they are made of K-resin plastic. Polypropylene vials are the only autoclavable vial option.

These vials are narrow vials, meaning the mouth opening is 25mm as opposed to wide vials that have a mouth opening of 28.5mm. Any narrow vial plug or closure can be used with these vials. All of our narrow vial closures can be found here: https://geneseesci.com/shop-online/category/7341

We highly recommend using our Nutri-fly pre-mixed Drosophila media. This food is available in the 3 main formulations currently in use by most fly labs: Molasses, Bloomington, and German formulations. The recipes used are the same recipes used by the Bloomington Drosophila Stock Center. The Nutri-fly pre-mixed media cuts out the hassle of purchasing, managing, and weighing out individual ingredients. Simply add water to the mix, bring to a boil, allow to simmer, add preservatives, then pour. Sizes are available for every Drosophila lab's needs, from single 1L packets all the way to bulk 100L powder. If you are insistent on following a Drosophila media recipe and purchasing separate ingredients, the BDSC lists their recipes here: https://bdsc.indiana.edu/information/recipes/index.html
