Match capacity and receiving opening
Transfer suitable liquids or powders through a disposable paper funnel with an adjustable stem opening.
Match capacity and receiving opening
Choose the 25 mL or 155 mL format according to the transfer volume and available space above the receiving vessel. The stem can be cut to the desired opening size or shape. Adjust it for the container mouth and material flow before beginning a transfer rather than assuming one uncut stem will suit every bottle. Both sizes are white and supplied in packs of 25.
Use the backrest to support the transfer
The manufacturerโs backrest feature supports hands-free use while pouring viscous liquids, and gentle pressure helps the funnel stay in position. The application photograph shows that support in use. Check the stability of the receiving vessel and funnel before pouring; a hands-free feature is not a substitute for a secure setup.
Keep heat and disposal limits in the decision
These disposable funnels are made from clay-coated heavy paper. Hot liquids are explicitly not recommended. Although the material is described as biodegradable in a standard municipal waste stream, used laboratory material must follow the disposal route appropriate to its contents. Do not treat a paper funnel as permission to discard hazardous or biological residues with ordinary waste.
Choose the exact catalog number
Compare the configuration and order unit in the ordering table. The listed pack belongs to one selected catalog number; a family photograph is not an assorted kit unless that row explicitly says assorted.
