Flasks & Bottles

Flasks and bottles are essential for liquid handling, mixing, storage, and media preparation in virtually every lab. This category includes flat-bottom and shake flasks, media bottles, reagent bottles, disposable sterile bottles, and graduated cylinders. Used across cell culture, bioprocessing, and analytical chemistry, these containers support sterile workflows, buffer storage, and sample scaling. Flat and shake flasks are used for microbial culture and protein expression, while media and reagent bottles store sterile liquids or reagents. Graduated cylinders offer precise volumetric measurements for solution prep. At Wasteless Bio, all flasks and bottles are unused, even if outer packaging is opened. Listings include material (glass, PETG, HDPE), volume, sterility, and autoclavability—helping researchers reduce waste and cost while maintaining safety and workflow integrity.
