✓Snug Fit with Protective PVC Coating:The soft PVC coating cushions direct contact with glassware while adding slight grip to prevent sliding. Helps protect flasks from scratches, chips, and accidental damage during heating
✓Heavy-Duty Weighted Construction:Each ring is intentionally weighted to provide balanced downward force, improving stability in active heating environments. The solid construction ensures long-lasting durability in laboratory use
