This premium borosilicate reagent bottle measures 4.6 inches in height with a base diameter of 2.2 inches and a 0.7-inch opening that slightly tapers. Made from high-quality borosilicate 3.3 glass, it features an acid-proof polypropylene stopper (socket size 19/26) and is autoclavable. Designed for laboratory use, it's also suitable for home applications or as part of a "potions" set. The bottle is top-rack dishwasher safe and can withstand high temperatures, with strain and softening points of 515°C and 820°C, respectively. Note that dimensions may vary slightly due to hand-blown craftsmanship.
