Product Description
Setting up reflux or distillation on a flat surface is simpler with a flask that stands on its own. These economical flat bottom boiling flasks sit steadily on the bench or hot plate and connect directly to standard taper glassware, so you can assemble apparatus without extra supports.
This listing is for Kimble catalog number 55055-250: ValueWare Flat Bottom Boiling Flask, 250 mL, Case of 12. Each flask has a short neck with a full-length Standard Taper 24/40 joint and is made from KIMAX borosilicate 3.3 glass for thermal shock resistance. Durable white ceramic enamel markings stay legible through washing. The flasks are designed to ASTM E1403, Type I, Class 4, and are offered in 125 to 1000 mL capacities. LIGHT LABS ships genuine DWK Life Sciences products with knowledgeable support from our Englewood, Colorado team.
