Square Bottom Drosophila Bottles | Case of 500

500 per case

6oz square bottom culture bottles for Drosophila population studies, large-scale crosses, and egg collection. Made in the USA. The square bottom geometry provides stable bench placement and packs more efficiently on incubator shelves than round bottles — no rolling, no wasted space. Graduation marks at 12.5 mL intervals for consistent fly food volumes across your stock collection. Save 41% compared to Genesee Scientific on the same bottle formats.

Polypropylene: Autoclavable (121°C / 15 psi) for repeated use. Durable and cost-effective for labs that sterilize and reuse bottles. Better optical clarity than polyethylene.
Polyethylene: Non-autoclavable, designed for single-use convenience. Buzz plug compatible with indent for secure fit.
Polyethylene Wide Ledge: Features an extended ledge that provides a secure platform for paper lid placement — lids stay put without tape. Non-autoclavable.

Pair with: Recycled polyester or sponge bottle plugs for secure containment and superior mite protection.
