Description
- Thickened Food & Lab Safe Composite Sealing Structure: The bottle cap adopts thick rigid food and laboratory standard plastic as outer body, with built-in flexible silicone sealing washer. Polished smooth inner contact surface forms mild buffer with glass bottle mouths, avoiding scratch abrasion during repeated twisting, opening and sealing cycles
- Comprehensive Sample Container & Liquid Isolation Layout: All threaded edges are finely polished without sharp burrs to prevent glass bottle mouth chipping and hand scratches. The elastic silicone washer fits tightly to form fully airtight enclosed space, blocking liquid leakage, volatile substance evaporation and external dust impurities from polluting internal liquid samples
- Standard Thread Universal Sample Bottle Matching Profile: Standardized thread specification fits most miniature glass vials, plastic sampling bottles, laboratory test containers and essential oil storage bottles. It satisfies storage demands of laboratory specimens, cosmetic liquid filling, portable essential oil travel packaging and small-volume handmade craft liquid preservation
- Precision Thread Quick Twist Sealing Construction: Uniform high-precision thread structure fits seamlessly with bottle necks, supporting fast manual twisting to open and close. No extra sealing adhesive tape or auxiliary tools are required for quick cap replacement and repeated sealed storage
- Chemical & Moisture Resistant Long-Term Stable Design: Inert stable plastic outer shell and elastic silicone washer maintain intact stable shape under long-time contact with essential oils and mild chemical reagents, as well as long-term indoor storage environments. Frequent opening and closing will not cause cap cracking, thread surface abrasion and silicone washer loosening
