Caplugs® Evergreen 60 mm Ribbed Polystyrene Laboratory Funnels, Natural, Non-Sterile, 100/Bag
These 60 mm ribbed polystyrene laboratory funnels deliver fast, drip-controlled transfers for everyday bench work. Internal ribs prevent airlock so liquids and free-flowing powders move without backflow, making them ideal for sample decanting, reagent transfer, and feeding filter paper during gravity filtration. Disposable design eliminates carryover between batches.

Frequently Asked Questions
What do the internal ribs do?
The molded ribs hold the funnel slightly off the receiving vessel's rim, letting displaced air escape. This prevents airlock and backflow, so liquids and powders flow smoothly and quickly.
Are these funnels sterile?
No. They are supplied non-sterile and are intended for general transfer, decanting, and filtration tasks that do not require aseptic conditions.
What is the funnel made of?
The funnel is molded from polystyrene (PS) in a natural color. PS offers good clarity and rigidity for routine aqueous and many general-purpose transfers; verify suitability before use with aggressive solvents.
How are these funnels packaged and sold?
They ship 100 funnels per bag, priced per pack. Each bag is lot-numbered for traceability and audit documentation.
