KIMAX® Heavy-Duty Beakers are low form beakers (Griffin beakers) with double capacity metric scale, thick uniform walls throughout, and extra wall thickness built into the evenly tooled top rim. The construction of these heavy-duty beakers is intended to prolong life expectancy with harder than normal usage (i.e. mechanical shock). The spout of these KIMAX® beakers is designed for optimum performance. 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 (low form, with spout heavy duty).
