These laboratory flasks are sterile Erlenmeyer flasks from NEST Scientific and MarathonLS. Volumes run from 125 mL to 2000 mL, molded in polycarbonate or PETG. Case packs range from 4 to 24 flasks.
Baffled flasks increase aeration for microbial shake culture, while flat bottom lab flasks suit suspension cell culture. Vent filter caps allow gas exchange during incubation. Seal caps and plug seal caps close the laboratory flask for storage or transport. The 2L High Efficient flasks come with a flat base or baffles.
