KIMBLE® 29052F-250 RAY-SORB® Squibb Pear Shaped Separatory Funnels with Yellow Color-Coded PTFE Stopper & PTFE Stopcock. These funnels are RAY-SORB® processed to protect light sensitive contents from shorter wavelength light. Standard Taper PTFE color-coded stopper and color-coded stopcock is supplied. Replacement stopper is 41901R. Replacement stopcock plug is 41500F. Lower stems have an ID large enough that a column of liquid will “break” with the stopcock closed, thereby giving a more complete separation and eliminating the necessity of emptying the funnel. Designed from ASTM Specification E1404, Type II, Class 2 requirements. Manufactured from 33 expansion, low extractable borosilicate glass conforming to USP Type I and ASTM E438, Type I, Class A requirements and then RAY-SORB® processed.
