These heavy wall round-bottom flasks will stand up to years of use. These flasks have standard taper outer joints and the side necks are offset at a 20 degree angle to provide better access when working with accessories such as addition funnels. Flasks with 29/26 center necks have a groove tooled just below the grind to aid in clamping of the flask.
This item comes in sizes from 100 to 22,000 mL in a variety of joint sizes. Additional joint sizes are available by special order.
