These Green Sure Grip Beakers have been ergonomically designed to make them very easy to hold, even for those users with small hands or a weak grip.The deep contoured grooves around the beakers not only make them easy to grip, but also help to prevent the beakers slipping through the fingers and therefore help to promote user confidence. Sure Grip Beakers are made from a very strong high quality plastic, that is free from PVC, and as such are almost unbreakable. Suitable for both hot and cold drinks, these beakers are dishwasher safe and can be used in the microwave or freezer. Sure Grip Beakers are also available in a range of other colours in this section of our web site. A range of lids is also available for use with this product, see list below.
