These closures for Drosophila vials and bottles allow for breathability for the Drosophila while helping to prevent mite contamination. Flugs are bonded dense weave cellulose acetate plugs and provide a better barrier to mites than cotton and paper lids. Reduced evaporation keeps food fresh longer.
Cotton Balls - these top-quality balls are an effective barrier to mite infestation.
Droso-Plugs- these are the densest foam closures available to fly labs. They are reusable (washable, autoclavable), making them the easiest closure available: insert/remove/gas.
