What QuinTron does

QuinTron Instrument Company, Inc. is a privately held, founder-owned medical device manufacturer founded in 1961 in Milwaukee, Wisconsin, currently headquartered at 2855 South James Drive, New Berlin, Wisconsin. The company specializes in breath analysis instrumentation and disposable sample collection products used to diagnose gastrointestinal disorders — principally Small Intestinal Bacterial Overgrowth (SIBO), Intestinal Methanogen Overgrowth (IMO), and carbohydrate malabsorption (lactose, fructose, sucrose). Its core product, the BreathTracker SC Analyzer, is a benchtop instrument that measures hydrogen (H2), methane (CH4), and carbon dioxide (CO2) in exhaled breath using long-life solid-state sensors with 1 ppm resolution for H2 and CH4, in contrast to electrochemical sensors that lose sensitivity and require regular replacement.

The company sells the BreathTracker SC directly to hospitals, clinics, and laboratories for in-office testing (quote-based pricing, with tests potentially reimbursable under CPT 91065), and complements it with a patented line of disposable collection devices: the EasySampler (closed-system for unsupervised at-home use, with up to 14-day sample stability), the AlveoSampler (in-office syringe-based collection), and the GaSampler (in-office bag-based collection). Substrate-specific at-home test kits (Glucose at $249, Lactose at $195, Fructose at $195, and Sucrose with a 10-unit minimum) are sold through the company's direct-to-consumer e-commerce store (checkout.breathtests.com) and via healthcare providers, with samples shipped to undisclosed partner laboratories that return results within 48-72 hours. QuinTron also handles fulfillment of The Healthy Gut's SIBO Cookbook Bundle ($65 for two cookbooks) and maintains FDA Registration #2124914, ISO 13485:2016 certification through 2026-07-19, and MDSAP certification.

The business model combines one-time capital equipment sales with a recurring consumables stream from disposable kits, distributed through a hybrid go-to-market: direct enterprise sales to clinicians, direct-to-consumer e-commerce for patients, and community-led engagement via prominent naturopathic and integrative medicine practitioners (Dr. Allison Siebecker, Dr. Nirala Jacobi, Dr. Michael Traub, Dr. Farshid Rahbar) who publicly reference QuinTron as the "gold standard." The company has 11-50 employees, no disclosed institutional funding or parent company, and no subsidiaries; leadership remains anchored by founder Lyle H. Hamilton, Ph.D., emeritus professor of physiology at the Medical College of Wisconsin. Notable non-clinical work includes the MARROW project with NASA, the Canadian Space Agency, and the University of Ottawa, in which QuinTron's modified collection hardware was used aboard the International Space Station to study astronaut bone marrow in microgravity.

Core offering

QuinTron designs, manufactures, and sells breath analysis instruments and disposable breath collection kits used to diagnose gastrointestinal disorders such as SIBO, IMO, and carbohydrate malabsorption. Its flagship BreathTracker SC analyzer measures hydrogen, methane, and carbon dioxide in exhaled breath, while the patented EasySampler, AlveoSampler, and GaSampler collection systems support both in-office and at-home testing workflows for healthcare professionals and patients.

Product overview

QuinTron Instrument Company offers a portfolio of medical devices and diagnostic products centered on breath testing for gastrointestinal disorders. The core product is the BreathTracker SC Analyzer, a hardware device that measures hydrogen, methane, and carbon dioxide in breath samples. This analyzer is sold alongside a suite of breath collection kits: the EasySampler (home use), AlveoSampler (in-office physician use), and GaSampler (in-office). QuinTron also offers substrate-specific at-home breath test kits (SIBO/Glucose, Lactose, Fructose, and Sucrose) that use the EasySampler collection system with different test substrates. A companion product, the SIBO Cookbook Bundle, provides dietary resources. Results from home collection kits are analyzed by QuinTron's partner laboratories and delivered within 48-72 hours.
