Frequently Asked Question

Q. Why are your chemicals so much less expensive than the same chemicals sold by your competitors?

Our size, operations, mission and mentality all contribute to the low prices. ZellBio is a small company dedicated to providing researchers the high quality chemicals they demand at low prices they desire. Small companies don’t require the margins of larger ones, allowing the researcher to pay for a chemical and not a company. We conduct our business online. We feature a streamlined operation with little overhead to lower costs as well. We were founded on providing a low cost alternative in the chemical market; that’s what we continue to do. Finally, we provide these chemicals at lower prices to allow researchers to do more, research more and discover more, hopefully making the world a better place.


Q. What types of experiments are your products qualified for?
