Screw On Funnel Set Shake Proof No Spill

Screw On Wide Funnel Set Shake Proof No Spill

This funnel screws directly onto bottles for a secure fit.

This is a modular, threaded funnel set designed for lab-style transfer of liquids or solids into common plastic bottles.

The shake-proof, screw-on design keeps the funnel securely attached — even when handling wet or semi-solid materials like coffee grounds or powders that often clog traditional funnels. Just shake gently: the funnel stays in place, and the material flows through smoothly.

🔬 Laboratory Applications:

• Transferring wet or granular materials
• Funnel-assisted shaking without dislodging
• Field-ready lab setups, composting, or chemical preparation

📦 Includes 6 variations:
– 3 sizes: 75mm / 105mm / 135mm
– Each version fits either cola bottles (large openings) or mineral water bottles with 27–28mm necks

📸 The GIF demonstrates how the funnel stays fixed while shaking — solving the common problem of clogging and accidental spills in gravity-fed setups. The material shown is wet coffee grounds, which tend to clump together and easily block regular funnels..

✳️ Designed for lab utility, DIY experiments, and practical everyday use.
