4ml 5ml Glass Dropper Bottle with Secure Lid

KANG HUA 16mm Glass Dropper Bottles – The Safe Choice Brands Trust Since 2010

Why Buyers Switched to Our Bottles

Last month, a perfume brand from Italy sent us an email: "We used to lose 12% of our stock during shipping because our old perfume bottles leaked. Your 16mm dropper bottles? Zero leaks in 5000 units shipped. That’s a $3,000 saving right there."

That’s the problem we solve daily. Too many glass containers look good on paper but fail in real use: penicillin bottles that don’t meet EU child-safety standards, Health product bottles that let moisture ruin herbal extracts, reagent bottles that drip chemicals all over lab benches.

Our 16mm glass dropper bottle was built to fix these headaches. We started with high-grade borosilicate glass (the kind labs use for chemicals) because a Canadian essential oil maker told us: "Cheap glass reacts with our oils, turning them brown." Ours? We’ve tested it with citrus oils, CBD tinctures, and even harsh cleaning solutions – zero reactions, every time.

The safety cap? That came from a pharmacy owner in Texas. "We had a close call with a toddler opening a medicine bottle," she said. Our cap needs two hands to open – firm pressure plus a twist – but still easy for adults. It’s why 80% of our pharmacy clients reorder quarterly.

Details That Matter in Real Use

• Neck Size: 16mm (we checked 200+ filling machines – this size fits 98% without adjustments)
• Glass: Borosilicate, 1.2mm thick (dropped from 3ft onto concrete? 9/10 survive – we tested 500 units)
• Heat Resistance: -20°C to 300°C (survives freeze-thaw cycles in cargo ships crossing the Atlantic)
• Capacity Options: 5-150ml
• Sealing: Double-layer (rubber stopper + screw cap) – we submerged a filled bottle in water for 72 hours? No leaks.

What Makes Our Bottles Different

Buyers Notice These Details

• No More Waste: "Our staff used to spill 5-8 drops every time with old droppers. Now? Exactly 1 drop per squeeze." – Lisa, aromatherapy brand owner (10ml bottles save her 20% oil annually)
• Kid-Proof, Adult-Friendly: "Parents love the safety cap – we’ve had zero complaints about kids getting into them." – Mark, natural remedy company (sold in 200+ US health stores)
• Survives Shipping: "We used to have 3-5 broken bottles per carton. With KANG HUA’s thicker glass? 1 broken in 10 cartons." – Juan, cosmetic manufacturer (saves $800/month on replacements)

Pro Tips for Best Results

1. First Clean: Rinse with warm water (not boiling – 60°C max) and let air dry. One customer used soap once – left a residue that messed with their perfume scent.
2. Filling: Leave 1cm space at the top. A skincare brand tried overfilling once – when the cap pressed down, oil leaked out. Oops.
3. Closing: Screw the cap until it’s tight, then give it a tiny extra twist. Not too hard – you don’t want to crack the glass (we’ve seen it happen!)
4. Storing: Keep away from direct sunlight. Amber glass is available if you’re storing light-sensitive stuff like citrus oils.
5. Checking Seals: Every 3 months, pull the rubber stopper out and check for cracks. One lab forgot to do this – reagent leaked, ruined $500 worth of equipment.
