Law of Conservation of Mass Experiment Apparatus – Bottle Type

Law of conservation of mass experiment apparatus designed to safely demonstrate mass before and after a chemical reaction.

This sealed plastic reactor allows students to observe that total mass remains constant during a chemical change, even when gas is produced. By keeping reagents separate until mixing and securely sealing the system, the apparatus supports clear, repeatable investigations in secondary school chemistry, making abstract theory easier to understand through hands-on experimentation.

Key Features

- Sealed reaction system allows accurate mass comparison before and after reaction
- Separate reagent containers prevent premature reactions
- Rubber seal securely traps gases produced during reactions
- Durable polypropylene construction for safe classroom use
- Easy disposal and clean-up after experiments
