Flugs® Closures for Vials and Bottles

Flugs are bonded dense weave cellulose acetate plugs for Drosophila vials and bottles. Flugs (short for Fly Plugs) are said to provide a better barrier to mites than cotton and rayon, and especially paper lids and foam plugs. Additionally, Flugs offer minimal shedding compared to cotton and rayon as well as reduced evaporation, which keeps food fresh longer.

Master Cases Quantities!  For your convenience, we have designed boxes which fit multiple cases of Flugs. We encourage customers to order flugs in multiples of Master Case quantities to help protect shipments and reduce freight costs.

Cotton & Rayon Balls & Rope

Thorough machine processing provides consistent uniformity of shape and size for maximum efficacy in vial plugging. These top quality balls are an effective barrier to mite infestation.

Our pharmaceutical grade cotton and rayon coil rope 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.

Press’n Seal™ Sealable Plastic Wrap

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 in 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.

Geneseal Adhesive Film™ for Vials

A revolutionary adhesive film developed specifically to optimize fly food preparation and preservation.

Save Food Preparation Time – 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! Use GENESEAL and leave the plugging for when flies are in the vials. Large or small, any fly facility can benefit with GENESEAL. Vials sealed with GENESEAL stay moist up to 3 times longer than plugged vials. So, more food can be prepared less often which cuts setup time by up to two thirds! Since the fly kitchen is no longer responsible for plugging, the individual laboratory/researcher can select and procure it’s own closures. Persons intollerant of cotton can use rayon…or foam. And labs who prefer the best barrier to mite infestation can use Flugs. Therefore, the fly kitchen need not be burdened with more work or hassle to accommodate individual needs or preferences.
