Kimax® low form beaker with thick uniform walls throughout and extra wall thickness built into the evenly tooled top rim. Spout is designed for optimum performance. Heavy construction is intended to prolong life expectancy with harder than normal usage (i.e. mechanical shock). Not recommended for use on hot plates where significant thermal gradients exist due to lack of agitation of contents or absence of a temperature control. All sizes have a durable matte finish marking area and a white graduated scale. Designed from ASTM Specification E960, Type II requirements.
