Masses and Lab Weights

Masses and lab weights for science lab use: hooked, slotted, and more.

Shop lab weights for a variety of science activities.

Get a metal mass set, available at two educational levels: starter and an advanced. The starter set is helpful in demonstrating how small a gram is. Use both sets for general projects or with one of our balances and scales.

A plastic mass set in primary colors introduces the concept of mass to early elementary kids. Younger students also love the mass cube set, which helps them visualize mass and volume.

Find large hanging weights and precision mass sets with accuracy to 0.01 gram. Get scale calibration weights in three different sizes. Also consider a demonstration balance, available with or without a weight set. Use it to show the relationship between weight and distance. It's a well reviewed teaching tool for anyone who wants an inexpensive but sturdy balance.
