Product Description
Round bottom flasks are the workhorses of synthesis and distillation, and an economical option makes it easier to keep plenty on hand. These ValueWare flasks heat evenly in mantles and baths and connect directly to standard taper glassware for reflux, distillation and rotary evaporation.
This listing is for Kimble catalog number 55285-500: ValueWare Round Bottom Flasks, 500 mL, Case of 10. Each flask has a short neck with a full-length Standard Taper 24/40 joint and is made from KIMAX borosilicate 3.3 glass, whose low expansion resists thermal shock. Sturdy walls minimize mechanical breakage, and white ceramic enamel markings are durable. They are designed to ASTM E1403, Type II, Class 3, and come in several capacities. Add it to your LIGHT LABS order alongside the rest of your glassware and closures.
