Overview
A comprehensive vintage educational chemistry kit branded by the Smithsonian Institution, designed to teach 'microchemistry' techniques using small-scale experiments. This set features a specialized three-panel folding case containing various chemical reagents, test tubes, pipettes, and a reaction plate.
Story
In 1991, NSI partnered with the Smithsonian to bring professional lab techniques into suburban bedrooms. Unlike the dangerous kits of the 1950s, this set focused on the precision of 'microchemistry,' using tiny amounts of chemicals.
Maker / Origin
Natural Science Industries (NSI) was a powerhouse in the 20th-century educational toy market, specializing in science kits that bridged the gap between play and academia. Their collaboration with the Smithsonian Institution lent a high degree of prestige and scientific accuracy to their products, making them a staple of museum gift shops.
Condition & Value
The case and manual show light wear consistent with age. The presence of most vials is a positive sign, though any dried or leaked chemicals would significantly decrease the value. The manual appears slightly creased but legible. Value is driven primarily by completeness and the condition of the chemicals.

Build on this identification
Layer in sold comps, value drivers, and venue guidance.
Comparable demand stays strongest where maker, originality, and venue confidence line up. Broader examples still trade, but the range tightens quickly when provenance, condition, or selling lane fit is missing.
Best Venue
Specialty auction or a focused dealer with buyers already in this lane.
Signed example with light edge wear and original frame.
Comparable format with stronger provenance and cleaner surface.
Smaller related piece with visible craquelure and trimmed margins.
Period match with softer condition and weaker subject matter.
