This tough, high-density polyethylene (HDPE) resilient protective netting fits snugly over laboratory glassware to absorb impact, reduce breakage, and safeguard against flying glass. Simply cut to desired length to fit most vessels. Use smaller diameter sizes for instruments such as thermometers, pipettes, electrodes, tubes, and syringes. Use larger diameter sizes for bottles, flasks, beakers, funnels, and columns.
