Genesee's Drosophila culture vials are precision moulded from pure high-quality polystyrene plastic. The straight-walled design allows for easy plugging and food filling and the flat bottom minimizes food dislodging while flipping flies. These narrow fly vials come pre-racked in cardboard 10 x 10 vial trays, so they can be filled and plugged directly from the case.

Polystyrene Drosophila vials offer glass-like clarity for excellent visibility. These shell vials are a safe and cost-saving alternative to glass vials. Polystyrene vials are not autoclavable.
