When Chicago Laboratory Supply and Scale Company was founded in 1886, few could have predicted that more than 135 years and one name change later, it would still be supplying the world’s scientists with the highest-quality instruments available.

But that is exactly the case.
Today, Stoelting  is composed of four separate Divisions.  Although Stoelting is a diversified company, the major product lines are all related to physiological, psychological, and psychophysiological measurement. 
This inter-relationship results in
exceptional synergism and cross-fertilization of ideas.  Breakthroughs in one of our Divisions routinely find application in another Division.  This kind of dynamic environment has been present at Stoelting from the beginning.

As a pioneer in the Physiological and Psychological apparatus fields, Christian Hans Stoelting built his company into one of the most successful and revered companies in the fledgling scientific world.

Tradition of innovation

In fact, from 1903 to 1943, Stoelting was nearly unchallenged as the principal provider of the material culture of American psychology.  And at the St. Louis Universal Exposition of 1904, C.H. Stoelting Co. was awarded Medals for Anthropometric Apparatus and Psychometric Apparatus, awards that hang on our walls to this day.
From those humble beginnings on Chicago’s west side, to our present-day headquarters in Wood Dale, Illinois, Stoelting has maintained a tradition of manufacturing and supplying superior instruments in worldwide service to science. 

Our goal

Stoelting Psychology continues to be a leader in the field of psychological assessment with tests used in clinical, research, and educational settings.  The Leiter International Performance Scale- Third Edition (Leiter-3) is the preeminent nonverbal assessment for cognition, attention, and memory.  The Stroop Color and Word Test is extensively used as a brief test of executive functions.  The Merrill-Palmer tests are broad early childhood developmental assessments.  Our Checklist for Autism Spectrum Disorders (CASD) is an accurate and brief diagnostic test of autism.  These tests and more continue to serve professionals to help understand their clients and provide treatment and ongoing evaluation.

At Stoelting, we are proud of our Tradition of Innovation, and we shall always have a strong commitment to support scientific research.  We seek to offer only high quality, reliable instruments, and support them with prompt, educated customer service from our staff of science professionals.
