Description
Product Overview
The 48pcs Breathable Film Bottle Caps are engineered from high‑performance expanded polytetrafluoroethylene (EPTFE), a material renowned for its chemical inertness, thermal stability, and exceptional water‑resistance. Each cap measures 0.87 x 0.87 x 0.2 inches and weighs just 0.64 ounces, making it lightweight yet robust enough to withstand rigorous laboratory handling. The caps feature a thin, flexible film that conforms tightly to standard bottle openings, creating a seal that prevents liquid leakage while allowing gas exchange when needed. This balance of breathability and barrier protection is critical for applications such as tissue culture, cell culture, and mushroom cultivation, where maintaining a controlled environment is essential. The product is manufactured by HEALSOPTHY, a trusted name in laboratory consumables, and carries the model number 6278102S1E3633A5S. With a best‑sellers rank of #19 in Quantitative Lab Filter Paper, these caps have proven their utility across a wide range of scientific protocols.

Usage
These caps are designed for versatility in the laboratory. Researchers can apply them to culture flasks, reagent bottles, and filter paper containers to create a leak‑proof environment that still permits necessary gas exchange. In tissue and cell culture, the caps help maintain sterility while allowing oxygen diffusion, supporting cell viability and growth. For mushroom cultivation, the caps prevent excess moisture loss and protect against contamination, ensuring consistent mycelial development. The easy‑attach design means users can quickly secure the cap with one hand, reducing setup time and minimizing exposure to the sample. The caps are also compatible with filter paper stickers and synthetic filter discs, expanding their utility to a range of experimental setups. Whether you are conducting quantitative filter paper assays, preparing sterile media, or performing delicate biochemical reactions, these caps provide a reliable sealing solution that enhances experimental reproducibility.
