This graduated flask features a pourout and deep-fluted sides to promote turbulence. The dam located below the sidearm retains untrypsinized tissue when decanting. Deep-skirted screw cap on sidearm prevents contamination of flask contents. Sidearm caps are size 20-415. Caps have white styrene-butadiene rubber liner. Wheaton 33* low extractable borosilicate glass meets ASTM Type I, Class A and USP Type I standards.
