Dr. Marian, TX University

I bought mason-jar airlock jars thinking they would work for my grant-funded gut-healing research. Mold! Oxygen-rich yeast! I was crushed thinking my entire research project was destroyed because of the poorly designed equipment.  One of my co-workers recommended your Pickl-It and now my mold-free, high-bacteria count research is back on track. Thank you for your superb product that is affordable, laboratory-quality equipment.
