Beaker lids and covers prevent contamination and content loss from spouted and spout-less beakers. Covers are available in PTFE plastic, due to its resistance to chemicals and temperature, as well as glass and metal. They are sized to tightly fit a specific beaker volume and diameter.
Reusable lids stretch easily and adapt to many container sizes, improves lab safety, enhances sample management, offers a more sustainable and cost-effective solution over foils, films and other single-use covers.
