8125–01 L Microplates, PS, Natural, Thermo Fisher/Corning Compatible — 290-8125-01L | 15/Box | Caplugs® Evergreen

24-Well Microplate Lids, PS, Natural — 290-8125-01L | 15/Box (105/Case)

Technical Narrative

The Caplugs® Evergreen is a 24-well Polystyrene (PS) microplate lid for standard SBS/ANSI-footprint 24-well plates — providing evaporation control, contamination protection, and gas exchange management during 24-well cell culture, virus propagation, organoid incubation, and sample archiving workflows. 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.

PS 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.

At $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. Verified compatible with Caplugs® Evergreen 290-8124-01F 24-well flat-bottom plates.

Frequently Asked Questions — Caplugs® Evergreen

Does the lid fit all standard 24-well plates?

The is designed for standard SBS/ANSI-footprint 24-well plates and is verified compatible with Caplugs® Evergreen 290-8124-01F plates. Most major brand 24-well SBS-standard plates (Corning, Thermo Fisher Nunc, Greiner, Falcon) are compatible. Non-standard footprints or plates with elevated well rims may not engage correctly. Always validate lid-to-plate fit with a sample pair before large-volume purchase.

Is the lid autoclave-compatible for cell culture use?

Yes. The is molded from Polystyrene (PS) and is autoclave-compatible at 121°C / 15 psi for sterilization before use in cell culture and pathogen propagation workflows. Autoclave in a pouch or wrapped in autoclave film — loose lids in an autoclave bag are acceptable for batch sterilization. Allow lids to cool completely before placing on culture plates.

Are the lids BPA-free?

Yes. The is molded from virgin Polystyrene (PS) containing no BPA and no phthalate plasticizers — suitable for cell culture, virology, and regulated laboratory applications.
