Ordered several preserved specimens (sheep brain, heart, eyes and a squid) that all arrived quickly. Specimens are high quality and will be great resources for my class. I will definitely be back when I need more biological supplies.

Great product. Maggots arrived alive and healthy.

My algae is growing fabulously. Instant delivery, amazing service!

Arrived on time- as always, and great condition. One happy don.

This is the second time that we have ordered from Darwin Biological. The materials provided are of high quality, just what we have needed for our medical ultrasound training. Their staff are conscientious and careful, ensuring that the materials arrive in the best possible condition. They are easy to communicate with and have been very responsive.

Quality products, and fast, friendly service. Always trust Darwin Biological with our classroom supplies.

Amazing service :). A couple of weeks ago I tried to order some maggots of the species Calliphora vomitoria from another website and they canceled my order. So then i found out about this company “Darwin Biological” and they’re the best maggots i’ve seen in my life. I chose the next day delivery option, arrived in time, and the little ones were all alive. Amazing service !!!

Great product. We use the owl pellets in our science workshops to teach the children about birds, owls and digestion. The children really enjoy. The pellets are sterile, high quality and contain really interesting bones from mice, voles, other small birds.

These really are great value agar plates. Well prepared, well packaged and work just as intended. Perfect for my needs!

Prompt delivery and items as described.

Fast delivery. Excellent quality. Thank you!

Arrived quickly, good quality.

Excellent customer service and speedy delivery! Have ordered twice in the last few years, students are happy

Perfect.

Arrived on time and was packed very well. My son used the sheep 's heart for dissection.
We are thankful and grateful for the sheep who gave the heart for dissection.
Thank you Darwin biological team for delivering the sheep heart on time.
