When buoyant Erlenmeyer flasks and volumetric glassware are submerged in heated or circulating water baths, they are highly prone to tipping over, resulting in ruined experiments and contaminated heating fluid. These heavy-duty lead weights easily slip over the neck of the flask, dropping the center of gravity and locking the vessel securely in an upright position.\u003cbr\u003e\u003cbr\u003eTo protect delicate glassware from scratching and to prevent the lead from oxidizing or contaminating the water bath, each ring is fully encapsulated in a thick, chemically resistant blue vinyl coating. The series offers both continuous Circular rings for standard immersion, and specialized 'C-Shape' rings that can be easily attached to vessels with side-arms or bulky tubing connections. Available in precise diameters and weights specifically calibrated to fit standard flask capacities ranging from 125 mL all the way up to massive 4000 mL vessels.\u003c\/p\u003e\n\u003ch2 class=\"mb-2 mt-4 font-display font-semimedium text-base first:mt-0 md:text-lg [hr+\u0026amp;]:mt-4\"\u003eFeatures and Benefits\u003c\/h2\u003e\n\u003cul class=\"marker:text-quiet list-disc\"\u003e\n\u003cli class=\"py-0 my-0 prose-p:pt-0 prose-p:mb-2 prose-p:my-0 [\u0026amp;\u0026gt;p]:pt-0 [\u0026amp;\u0026gt;p]:mb-2 [\u0026amp;\u0026gt;p]:my-0\"\u003e\u003cp class=\"my-2 [\u0026amp;+p]:mt-4 [\u0026amp;_strong:has(+br)]:inline-block [\u0026amp;_strong:has(+br)]:pb-2\"\u003eVinyl-coated lead ring will not mark or scratch benchtops and labware\u003c\/p\u003e\u003c\/li\u003e\n\u003cli class=\"py-0 my-0 prose-p:pt-0 prose-p:mb-2 prose-p:my-0 [\u0026amp;\u0026gt;p]:pt-0 [\u0026amp;\u0026gt;p]:mb-2 [\u0026amp;\u0026gt;p]:my-0\"\u003e\u003cp class=\"my-2 [\u0026amp;+p]:mt-4 [\u0026amp;_strong:has(+br)]:inline-block [\u0026amp;_strong:has(+br)]:pb-2\"\u003eC-Shape Style allows some manual size variation for a customized fit\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 class=\"mb-2 mt-4 font-display font-semimedium text-base first:mt-0 md:text-lg [hr+\u0026amp;]:mt-4\"\u003eSpecifications\u003c\/h2\u003e\n\u003cul class=\"marker:text-quiet list-disc\"\u003e\n\u003cli class=\"py-0 my-0 prose-p:pt-0 prose-p:mb-2 prose-p:my-0 [\u0026amp;\u0026gt;p]:pt-0 [\u0026amp;\u0026gt;p]:mb-2 [\u0026amp;\u0026gt;p]:my-0\"\u003e\u003cp class=\"my-2 [\u0026amp;+p]:mt-4 [\u0026amp;_strong:has(+br)]:inline-block [\u0026amp;_strong:has(+br)]:pb-2\"\u003eColor: Blue\u003c\/p\u003e\u003c\/li\u003e\n\u003cli class=\"py-0 my-0 prose-p:pt-0 prose-p:mb-2 prose-p:my-0 [\u0026amp;\u0026gt;p]:pt-0 [\u0026amp;\u0026gt;p]:mb-2 [\u0026amp;\u0026gt;p]:my-0\"\u003e\u003cp class=\"my-2 [\u0026amp;+p]:mt-4 [\u0026amp;_strong:has(+br)]:inline-block [\u0026amp;_strong:has(+br)]:pb-2\"\u003eFits Flask Size: 125-500 mL\u003c\/p\u003e\u003c\/li\u003e\n\u003cli class=\"py-0 my-0 prose-p:pt-0 prose-p:mb-2 prose-p:my-0 [\u0026amp;\u0026gt;p]:pt-0 [\u0026amp;\u0026gt;p]:mb-2 [\u0026amp;\u0026gt;p]:my-0\"\u003e\u003cp class=\"my-2 [\u0026amp;+p]:mt-4 [\u0026amp;_strong:has(+br)]:inline-block [\u0026amp;_strong:has(+br)]:pb-2\"\u003eInner Diameter: 1.9 in (4.2 cm)\u003c\/p\u003e\u003c\/li\u003e\n\u003cli class=\"py-0 my-0 prose-p:pt-0 prose-p:mb-2 prose-p:my-0 [\u0026amp;\u0026gt;p]:pt-0 [\u0026amp;\u0026gt;p]:mb-2 [\u0026amp;\u0026gt;p]:my-0\"\u003e\u003cp class=\"my-2 [\u0026amp;+p]:mt-4 [\u0026amp;_strong:has(+br)]:inline-block [\u0026amp;_strong:has(+br)]:pb-2\"\u003eMaterial: PVC\u003c\/p\u003e\u003c\/li\u003e\n\u003cli class=\"py-0 my-0 prose-p:pt-0 prose-p:mb-2 prose-p:my-0 [\u0026amp;\u0026gt;p]:pt-0 [\u0026amp;\u0026gt;p]:mb-2 [\u0026amp;\u0026gt;p]:my-0\"\u003e\u003cp class=\"my-2 [\u0026amp;+p]:mt-4 [\u0026amp;_strong:has(+br)]:inline-block [\u0026amp;_strong:has(+br)]:pb-2\"\u003eOuter Diameter: 3 in (7.5 cm)\u003c\/p\u003e\u003c\/li\u003e\n\u003cli class=\"py-0 my-0 prose-p:pt-0 prose-p:mb-2 prose-p:my-0 [\u0026amp;\u0026gt;p]:pt-0 [\u0026amp;\u0026gt;p]:mb-2 [\u0026amp;\u0026gt;p]:my-0\"\u003e\u003cp class=\"my-2 [\u0026amp;+p]:mt-4 [\u0026amp;_strong:has(+br)]:inline-block [\u0026amp;_strong:has(+br)]:pb-2\"\u003eQuantity: 1 Each\u003c\/p\u003e\u003c\/li\u003e\n\u003cli class=\"py-0 my-0 prose-p:pt-0 prose-p:mb-2 prose-p:my-0 [\u0026amp;\u0026gt;p]:pt-0 [\u0026amp;\u0026gt;p]:mb-2 [\u0026amp;\u0026gt;p]:my-0\"\u003e\u003cp class=\"my-2 [\u0026amp;+p]:mt-4 [\u0026amp;_strong:has(+br)]:inline-block [\u0026amp;_strong:has(+br)]:pb-2\"\u003eShape: C\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 class=\"mb-2 mt-4 font-display font-semimedium text-base first:mt-0 md:text-lg [hr+\u0026amp;]:mt-4\"\u003eAcademic and Institutional Pricing\u003c\/h2\u003e\n\u003cp class=\"my-2 [\u0026amp;+p]:mt-4 [\u0026amp;_strong:has(+br)]:inline-block [\u0026amp;_strong:has(+br)]:pb-2\"\u003eLabSupplies.com offers tiered quantity pricing for academic and research institutions.
