Product Description
Microscale reactions benefit from a flask that concentrates small volumes at the bottom and offers a sealed side port. This KONTES pear-shaped flask does both, giving you a threaded sidearm for a thermometer, gas inlet or syringe sampling. It is ideal for teaching labs and small-scale synthesis.
This listing is for Kimble catalog number 251450-0015: KONTES Pear Shaped Distilling Flask. The heavy wall flask is made from low-extractable, 33 expansion borosilicate glass meeting USP Type I and ASTM E438 Type I, Class A. Its threaded sidearm takes an open-top BEVEL-SEAL nylon cap that can hold an O-ring for a thermometer or inlet tube, or a penetrable liner for syringe sampling. It includes one size 010 FKM O-ring and one PTFE-faced silicone liner, holds 15 mL and has a 14/20 joint. LIGHT LABS supplies the complete DWK Life Sciences line, including Kimble, Wheaton and DURAN labware.
