• 8oz dropper assembly supports larger liquid volumes
• 28/400 thread size fits compatible lab bottles
• 7x130mm glass pipette provides extended reach
• Pack of 12 supports small-group lab setups
• Glass construction resists staining from common reagents

These glass dropper caps are designed for controlled liquid dispensing in classroom and laboratory settings. When paired with compatible bottles, they support careful transfer of reagents and prepared solutions during chemistry and biology instruction. The extended dropper length allows access to deeper containers while maintaining measured delivery during structured experiments.
