The precision lid geometry provides consistent friction engagement with standard 24-well plate flanges — secure enough to prevent accidental dislodgement during incubator stacking and plate transport, while allowing the CO₂\/O₂ gas exchange required for mammalian cell culture atmosphere equilibration. Natural transparent PS allows visual monitoring of well filling and cell confluency without lid removal.\u003c\/p\u003e \u003cp\u003ePS construction is autoclave-compatible at 121°C for sterilization before use in contamination-sensitive primary cell culture and virus propagation workflows. Autoclave compatibility is the critical feature distinguishing this lid from the 24-well non-autoclavable lid formats — for cell culture, pathogen propagation, and biosafety-level workflows where the lid must be sterilized before use rather than relying on the manufacturer's non-sterile supply. The 15\/Box (105\/Case) format delivers per-lid economics suited to high-plate-count cell culture programs.\u003c\/p\u003e \u003cp\u003eAt $77.67 per Box of 15 — $0.7398 per lid — the delivers 24-well lid coverage at economics supporting dedicated lid-per-plate allocation for the duration of multi-day cell culture experiments.
