Cole-Parmer Erlenmeyer flasks undergo a gamma sterilization process in the USA to virtually eliminate all organisms. The manufacturing process achieves an extreme Sterility Assurance Level of SAL 10–6. The flasks are certified as DNase/RNase-free and nonpyrogenic which makes them ideal for applications in microbiology. Flasks are molded from virgin, clear, and nonleaching polycarbonate resin, keeping their optical clarity after sterilization.
Use as a standard Erlenmeyer flask on top of any platform or within shaking incubator clamps. Choose options with a flat or baffled bottom. The baffle indents create a turbulent flow when used with shakers, improving oxygenation and gas transfer.
Create your own custom flask and top connectors for your specific application. A vented cap with a 0.2 µm hydrophobic membrane is available (model 06059-22).
Both flasks and leakproof caps are autoclavable at 15 psi and 121°C for 20 minutes.
Do not use flasks under pressure or vacuum, do no use flasks at temperature greater than the rated maximum, do not store oxidizing agents in flasks, and do not flame flasks.
