Economical foam calorimeter to investigate heat transfer.

• Lids hold thermometers securely
• Foam helps reuce thermal energy lost to the air
• Exterior dimensions: 4.25"H×4"dia.
• Interior dimensions: 4"H ×4"dia.

These foam calorimeter cups have excellent insulating properties so users can investigate thermal energy with minimal loss to the environment. The lids have holes for inserting a thermometer or temperature probe.

The maximum water capacity with lid on is 400 ml.
