Kimble® KIMAX® RAY-SORB® Squibb Separatory Funnel for Light Sensitive Samples with PTFE Stopcock & [ST] PTFE Stopper

KIMAX® Squibb pear-shaped separatory funnel with RAY-SORB® and color coded handle are supplied with a PTFE stopper and stopcock. Lower stems have an I.D. 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. RAY-SORB® protects materials that are sensitive to the light of shorter wavelengths. Designed from ASTM Specification E1096, Type 4 Requirements. Replacement Stopper: 41901R.
