Calling all budding astronomers! Take your star-gazing to a whole new level with this kid-friendly telescope and accompanying journal packed with facts and fun activity prompts.
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.
