Bel-Art Polypropylene 250ml Squibb Pear-Shaped Separatory Funnel
- FEATURES A 4MM STOPCOCK PLUG OF NON-STICK PTFE AND SCREW CAP CLOSURE STEAM AUTOCLAVABLE (EXCEPT STOPPER) AT 121°C (250°F) STEM LENGTH: 40MM (1.57") WITH A 9.5MM (³/¿") O.D.
Yes. This funnel is made from polypropylene and is resistant to most chemicals, including hydrofluoric acid — a reagent that rapidly attacks glass, making polypropylene a necessary choice for HF-containing extractions.
The funnel body is steam autoclavable at 121°C (250°F), but the stopper is not autoclavable and must be removed before autoclaving.
The 4mm stopcock plug is made from PTFE, a non-stick fluoropolymer. This means it does not require grease to operate smoothly and will not seize or bind, reducing contamination risk and making it easier to control flow during extractions.
Yes. The funnel is made from translucent polypropylene, so you can observe the two liquid phases and identify the interface layer to guide accurate separation.
The stem is 40mm (1.57") long with a 9.5mm (3/8") outer diameter. These dimensions are relevant when selecting a compatible ring stand support, receiver flask, or tubing connection for your laboratory setup.
