Wire Gauze w/Ceramic Center 5 inch

Although most laboratory glassware is Pyrex, Bomex or similar heat resistant glass, none of them should ever be in direct contact with a flame. The only exception is a Test Tube and even that should be kept moving in & out of the flame. The proper way to heat materials in laboratory glassware (when using an open flame) is to place a Ceramic Center Wire Gauze between the flame and glassware. Ours is an extra stout wire gauze with a fireproof ceramic center. The sides are turned in so no sharp edges protrude. Recommended for all glassware.
