“It was surprisingly pleasant to find a lab which works to EU-standards in the US. It’s clear you work with integrity as well.”

“Please do not hesitate to use us as a reference. Any company requiring the use of respirometric technology will benefit from doing business with you. Your attitudes are a breath of fresh air. You truly are an extraordinary company.”

“The respirometric research work that Respirtek, Inc. accomplished for us saved our company months of development work and eliminated critical uncertainties from our commercialization process.”

“Your knowledge of respirometric technology is exceptional. The reports of the work were clear, concise and timely. And all of you were outstanding responding to our needs and requirements by your innovativeness.”

“From the first “cold call” I made when I connected with BJ through the many discussions and exchanges that have ensued over the last 9 months you have been intellectually engaged in our program and have made meaningful contributions that far exceeded the mechanics of generating high quality data. From helping design the best experimental approach through to the timely delivery and interpretation of the data, including the patience you exhibited in educating a non-microbiologist client, the experience with RespirTek has been personally rewarding…”

“Approaching the end of the current program of respirometry testing, I wanted to let you know that I have been exceptionally pleased with the service provided by Respirtek, Inc. Frankly, to use the term “service” does not do justice to the approach you take in running your company, which is clearly aimed at forming a problem solving partnership with your clients.”
