The Ballistic Pendulum is spring-loaded for easy investigations.

A variety of powders ensure that you are prepared for collecting evidence in any field condition.

An excellent set of materials for demonstrating electromagnetism and induced currents, the set includes two electromagnetic coils mounted on plastic saddle blocks, round and square iron cores, split round iron cores, a double core, and a card for showing lines of force. Set of two.

For all Optical Applications

Right angle and equilateral prisms are available in a variety of forms.

Understand Distillation and Intermolecular Forces with this Real Life Application.

Useful for collision and pendulum experiments.

Demonstrate Relationships Between Atoms

Does Your Patient Have Kidney Disease?

Unit consists of a sturdy metal frame carrying a DC motor with an eccentric shaft for exciting the vibrations. Clamp the frame to a table, attach a string and then simply use masses and a pulley to put tension on the string.

Perform an electrolytic redox reaction to create tin crystals in a solution.

Apply powder and dust away excess to highlight fingerprints

Absorbs the widest range of acids, bases and unknown liquids - even those with high concentrations like 98% sulfuric acid and 30% sodium hydroxide. Chemical-resistant mat won't degrade or cause a dangerous reaction upon contact with corrosive spills. Eight layers of 100% polypropylene are thermally bonded to make PIG Mat exceptionally strong; won't rip, tear or fray even when saturated. Exclusive dimple pattern speeds wicking of liquid throughout mat for faster, easier cleanup. Highly absorbent, fine-fiber construction won't leave behind liquids or fiber residue.

Easily determine pH with the universal indicator chart.

These springs are an oversized demonstration of Hooke's Law.
