The 6oz square bottom Drosophila bottles are precision molded from pure, virgin medical grade polyethylene. While not autoclavable, polyethylene bottles have better transparancy and the softest, most pliable top. These high-quality bottles are thoughtfully designed with thin walls for the best visibility and graduation marks that are useful for pouring Drosophila media. The square bottom is designed with rounded edges, which means more surface area for fly food to form a tight seal that secures it in the bottom of the bottle making them extremely easy to use when flipping flies.
6oz bottles are now packaged in our NEW environmentally friendly and space saving packaging. You receive 2 x 250 bottles per box, which uses 30% less cardboard than the industry standard single 500 piece box. This means less natural resources used to produce packaging, saving on storage space and reduced transportation footprint. The fly bottle openings are engineered to accept any standard size closure including paper lids, foam Droso-plugs?, cotton balls, rayon balls and Flugs?.
