These closures for Drosophila vials and bottles allow for breathability for the Drosophila while helping to prevent mite contamination. There are a variety of different options to suit the needs of every lab.
Flugs: Flugs® are made of Bonded Dense Weave Cellulose Acetate which provides an excellent barrier to mite infestation, they are said to provide a better barrier to mites than cotton and rayon, and especially paper lids and foam plugs. Reduced evaporation keeps food fresh longer. These closures are precision manufactured from our very own dies for consistent fit and minimal waste, and offer minimal shedding compared to cotton and rayon.
Paper Lids: These lids are used as closures for stock bottles. They have a non-wax surface for breathability. These lids can be used either with or without the pull tab.
Rayon & Cotton Balls/Rope: These top-quality balls are an effective barrier to mite infestation. Thorough machine processing provides consistent uniformity of shape and size for maximum efficacy in vial plugging. Also available as pharmaceutical grade cotton and rayon coil rope which can be pulled or cut apart in any length to effectively plug any size vial or bottle. These coils conform to USP (current edition) Purified Rayon and Purified Cotton, respectively.
Geneseal: A revolutionary adhesive film developed specifically to optimize fly food preparation and preservation. Plugging vials is the most time consuming, labor-intesive task performed in a fly kitchen and it’s no longer necessary! A sheet of Geneseal is applied to a tray of 100 vials in just seconds. Vials sealed with Geneseal stay moist up to 3 times longer than plugged vials.
Droso-Plugs: The Droso-Plugs® are the densest foam closures available to fly labs. They are reusable (washable, autoclavable), making them the easiest closure ever available. Recommended autoclave settings: 15min, 121° & 15psi (avoid dry cycle) Dry on a rack in a well-ventilated room.
Press'n Seal: Use Glad Press'n Seal sealable plastic wrap to "plug" vials in the fly kitchen, leaving the real plugging to be done when flies are on the vials. The application of this new sealable plastic wrap not only saves time in the food preparation facility, but also in the lab since the vial user does not need to unplug each vial prior to use. The seal has been found to significantly increase the shelf life of prepared fly food.
