Product Description
Connecting a separatory funnel directly into a reaction setup or receiving flask avoids spills and makes inert-atmosphere workups possible. These pear-shaped Squibb funnels end in a 24/40 standard taper joint, so they seat securely on flasks while delivering a clean, controlled drain.
This listing is for Kimble catalog number 636281-2000: KONTES Squibb Pear Shaped Separatory Funnel, Without Stopper, 2000 mL. Funnels are made from 33 expansion low-extractable borosilicate glass meeting USP Type I and ASTM E438 Type I, Class A. Each has an 821001 PTFE stopcock plug, a 24/25 top joint and a 24/40 bottom joint. The 636280 series includes a stopper (replacement 850400-2425), while the 636281 series is supplied without one. Sizes are 500 mL to 2000 mL. Add it to your LIGHT LABS order alongside the rest of your glassware and closures.
