We help teachers help their students...

Make exciting discoveries about living organisms, the local environment, the planet, and beyond.

The Connecticut Valley Difference
Over 55 years ago our founder, Marschall P. Lohr, began culturing protozoa and algae from local ponds for use as educational specimens. Area science teachers, impressed with the consistent high quality of the cultures, eagerly supported Mr. Lohr's company. Since then, Connecticut Valley Biological has continued to build a reputation for excellence that now covers over 10,000 unconditionally guaranteed products used for teaching a wide range of topics, in biology and life science as well as earth and space science.

Appreciative educators still insist on reliable Connecticut Valley specimens. Today, we also help them supplement their students' direct observations with a wide variety of related materials.

Still family-owned, Connecticut Valley Biological remains committed to providing the high level of service widely recognized by our thousands of loyal customers. We take great pride in knowing that in elementary through college levels, teachers depend on our materials to help their students experience the thrill of scientific discovery.

Our staff prides itself on assisting you with your every need. Whether preparing your specimens, supplying your materials or answering your questions, we are always here to offer you our support. Take advantage of our years of experience, we are your partner in science teaching!

Institutional Orders
We don’t use phone menus - a real live person will answer your call! Our friendly, knowledgeable staff is always eager to answer any questions or assist you in the ordering process.

New accounts are easy to set up: purchase orders are always welcome, but if your school doesn't use them we’ll work with you and try to accommodate your system. We often process “blanket” or “call in” orders so you can get your ordering out of the way early in the season, and wait until later to give us the shipping dates.

Items in stock can usually be shipped the same day (upon request), provided we receive your order before noon (EST).

We're happy to respond to requests for quotations, and we would appreciate the opportunity to bid on contracts for your school or district.

Your Satisfaction is Guaranteed
Our 100% Satisfaction Guarantee: If for any reason you are not satisfied with any product, you may return it for a replacement, a refund or a credit. Any live specimens found to be unsatisfactory upon arrival will be replaced, or a full credit given, if notified within 48 hours. Live delivery to foreign countries are not guaranteed.
