Bumper guard for Volumetric Flask

The Bumper Guard for Volumetric Flask is a durable, elastic safety collar designed to protect the narrow neck and body junction of volumetric flasks from breakage due to tipping, clashing, or sudden impacts. Made from chemically resistant rubber or silicone, this protective ring acts as a shock absorber, preventing cracking or shattering that can result from routine lab handling. The bumper guard snugly fits around the shoulder of the flask, often just below the neck, without interfering with volume markings or stopper placement. It is reusable, autoclavable, and compatible with glass and plastic flasks of standard sizes (e.g., 100 mL to 2 L).
