Trouble with water bath experiments?
Flask weight rings are the simple solution!
Fits 50-2000 ml flasks
Vinyl Coated Cast Iron Ring for stability
Step 1: Preparation
Check that the weight ring is clean and in good condition.
Choose the appropriate size of the weight ring based on the flask’s capacity (diameter).
Step 2: Installing the Weight Ring
Slide the weight ring onto the neck of the flask.
Make sure: The weight ring always stays above the liquid level and the flask remains in a vertical position.
Step 3: Stability Check
Observe for 1 minute to ensure the flask remains stable while boiling.
Note:
Use at approximately 100°C (212°F). Do not exceed 121°C (249.8°F).
If the flask still wobbles: try a larger weight ring or add additional support.
If boiling is too vigorous: lower the heating temperature or use a larger water bath.
Keep your flask steady and your experiments on track!
