Polypropylene (PP) lids offer broader chemical resistance versus PS — particularly for DMSO-containing compound storage plates, organic solvent-exposed assay plates, and autoclave sterilization workflows where PS lid integrity may be compromised. Natural transparent construction allows visual monitoring of plate contents and well-filling status without removing the lid.\u003c\/p\u003e \u003cp\u003eThe precision-molded lid geometry provides consistent friction engagement with standard 48-well plate flanges — tight enough to prevent accidental dislodgement during incubator stacking and robotic plate handling, while loose enough to allow the gas exchange required for mammalian cell culture CO₂ equilibration. Autoclave compatibility at 121°C enables sterile lid supply for contamination-sensitive cell culture applications. The 15\/Box (105\/Case) format delivers the per-lid economics suited to high-throughput plate-based screening programs.\u003c\/p\u003e \u003cp\u003eAt $77.67 per Box of 15 — $0.7398 per lid — the delivers consistent plate coverage at bulk economics.
