Rings fits neatly around the neck of filtering flasks with side-arm tubing connections. No need to disconnect the tubing and possibly compromise the process. The open ring is made of lead and covered with Vikem® vinyl coating to protect glassware. It is flexible enough to be pulled apart to accommodate a wider vessel. Available in four diameter/weight combinations to meet the needs in your lab.
Vikem® Vinyl Coated Lead Rings stabilize glassware immersed in water baths reducing floating, breakage and chemical spills. The bright red Vikem® vinyl coating is chemical-resistant and will not scratch flasks.
