Frequently Asked Questions (7 Questions Answered)
Q1: Do bottle stoppers work on all bottle sizes?
Most universal silicone stoppers fit standard 750ml bottles with neck openings between 17mm and 20mm.
Q2: How long does a vacuum pump bottle stopper keep liquids fresh?
Vacuum pump stoppers extract oxygen from the headspace, extending freshness for 7 to 14 days in the refrigerator.
Q3: Can you store a bottle horizontally on its side with a stopper?
Only stoppers with locking clamp wings or tight silicone expansion seals prevent leaks when bottles are laid flat.
