Featuring a unique design for both storing and measuring chemistry, the 64 oz Squeeze 'n' Pour Bottle from LegacyPro is constructed from durable chemical-resistant polypropylene, making it ideal for use with various chemical types. Intended for keeping stock solutions, the dual opening design allows you to measure chemistry using the integrated measuring chamber for quickly making working solutions. By squeezing the bottle, the liquid chemistry will fill the 4 oz / 120mL graduated chamber, which can then be easily poured out; saving the need to measure in a separate graduate.
