The quintessential laboratory piece. Made from thick borosilicate glass, these flasks tolerate rapid changes in temperature. You can place this quality flask directly on a naked flame and heat its contents, before transferring it straight to an ice bath to chill. The narrow conical neck prevents spilling when the contents are swirled. Available in a variety of sizes, and bulk-buy packs.
These flasks have a beaded rim, and are manufactured to ISO 1773, ensuring quality in construction and measurements.
