STOPPERS – “hallow glass” – “hexagonal” – “clear”

Manufactured from borosilicate 3.3 glass according to DIN 12252 standard.
Hexagonal flat head prevents the stopper from rolling on the bench and avoids the breakage risk.
A pointed, round formed “drip-tip” stopper lower end guarantees return of the adhered liquid back to the flasks.
