Product Description
Gentle on shear-sensitive cells and tough enough for repeated use, these flat-bottom Erlenmeyer flasks cover everything from a 125 mL starter culture to a 3L production run. A smooth, non-baffled interior keeps mixing gentle for mammalian and insect suspension lines.
This listing is for NEST catalog number 785001: 2L Erlenmeyer Shaker Flask, Polycarbonate, Flat Bottom, Plug Seal Cap, Sterile, Case of 6 (6 x 1). Each flask is molded from clear, impact-resistant USP Class VI polycarbonate with a molded graduated scale and capped with a USP Class VI polypropylene plug seal cap or a vented cap fitted with a 0.22 µm hydrophobic PTFE membrane. Flasks ship individually bagged and E-beam sterilized to SAL 10^-6, and can be autoclaved and reused 5-6 times (vent caps are not autoclavable; sterile replacement caps are sold separately). Manufacturing takes place in a cGMP, ISO 13485 facility with ISO 7 cleanroom molding and packing. Order it from LIGHT LABS alongside the rest of your NEST plastics and consumables.
