Polystyrene Disposable Funnels

Constructed from high-purity white polystyrene (PS), these funnels fully comply with EU food contact requirements and FDA regulations. Liquid variants feature integrated venting fins along the stem to equalize pressure during high-speed pours into narrow-neck containers, along with a molded suspension eyelet for convenient handling. Powder variants feature a short, wide-bore outlet stem to prevent material bridging and choking during the transfer of cohesive granules or fine powders.

Key Functional Benefits:

• Class 7 Cleanroom Manufacturing: Produced and individually packaged under ISO Class 7 cleanroom conditions to ensure absolute purity for high-grade QA/QC and sampling routines.
• Specialized Liquid & Powder Architectures: Choose between a long-stem liquid funnel with venting fins to prevent air locks, or a wide-bore powder funnel designed to prevent bridging and clumping.
• Full Regulatory Compliance: Formulated from food-safe white polystyrene meeting both EU food contact standards and U.S. FDA regulations.
• Sterile & Non-Sterile Options: Available in standard individually wrapped formats or gamma-sterilized versions for aseptic processing and environmental sampling.
• Filter-Paper Ready: Smooth internal cone geometry makes liquid variants an ideal support ring when using folded filter paper for quick benchtop clarify-filtration.

Single-Use Design: Do not autoclave or dry-heat sterilize. Intended strictly for single-use applications to eliminate cleaning validation protocols.
