Product Description
Push oxygen transfer higher without moving to bigger shakers: these single-use baffled Erlenmeyer flasks churn the culture as they swirl, driving better aeration for fast-growing bacterial and suspension cultures. Each flask arrives sterile and ready to fill, so there is no washing, wrapping or autoclave queue between runs.
This listing is for NEST catalog number 783311: 500 mL Erlenmeyer Shaker Flask, PETG, Baffled, Vented Filter Cap, Sterile, Case of 12 (12 x 1). The flask body is molded from crystal-clear USP Class VI PETG with an embossed graduated scale, and the cap is USP Class VI polypropylene, offered as a solid plug seal or a vented cap with a 0.22 µm hydrophobic filter. Flasks are produced in a cGMP, ISO 13485-certified facility, molded and packed in an ISO 7 cleanroom, individually bagged and E-beam sterilized to SAL 10^-6. Every lot is tested free of pyrogens, cytotoxins, DNase/RNase and DNA. Add it to your LIGHT LABS order and keep your bench stocked with genuine NEST consumables.
