Manufactured according to BS.1922 out of borosilicate glass. Each measure is Government Stamped. This indicates that each graduation line has been independently checked by a notified body to ensure that the volume is correct.
These beaker measures have been developed for intensive dispensing use. Made in heavy walled borosilicate glass with permanent enamel graduations. The flat bottom allows for easier stirring on hotplates and homogeinising than the more traditional designs.. They are also lighter, which aids handling, especially in the larger sizes. The calibration line spacing and accuracy are the same as traditional conical and bell measures.
