Hearts were in good quality for practical activities. It was treated well to have the main blood vessels preserved, great for learning.
used this product before, good quality, very reliable, works every time
definitely worth to buy.
Darwin are very reliable and always deliver excellent products.
Excellent sample , plenty of daphnia in all sizes, even had several water boatmen and other life too. Good value for money and perfect for our project.
The sample was excellent , absolutely teeming with life, and came very well packed. Very good for the price charged and perfect for our project.
I am happy with the quality of the products provided by Darwin! Will purchase from them again!
A good sized bunch of Elodea that grew nicely and worked well for our photosynthesis experiments.
This was my first purchase from Darwin Biological and my first time purchasing 'fresh'/unpreserved rats.
Dealing with Darwin was easy - my emails were replied to quickly and I was able to call and ask for advice about delivery times. Rats were held after my order was placed, and they were posted out, at the time of my request, on 24 hour delivery, in an insulated bag.
The rats were of very good quality but as it was my first time using unpreserved rats for dissection I was slightly unprepared for the subtle differences in appearance from the preserved specimens I would normally use. My students found this dissection a challenging one but they all thoroughly enjoyed the hours they spent completing it.
Great service, the fish heads arrived promptly, excellently packaged to keep them frozen
We purchased one pellet for a home education online primary science lesson and my daughter was fascinated with what we found inside and was an excellent activity and we leaned a lot. My only criticism is the hefty £7.50 postage cost which seems excessive to say the least for one tiny pellet that weighed virtually nothing. That said the pellet arrived in good time and was well packaged.
Good quality eyes. They were sent out promptly and were still frozen when they arrived. After thawing they were in good condition ready for disection.
Very happy with my order. It was a good strong culture which arrived promptly and grew on well.
Very happy with my order. It was a good strong culture which arrived promptly and grew on well.
Unfortunately, our order was 'missed' even though I had paid extra for a next day delivery. Our Year 8 students were unable to complete their planned lesson and were hugely disappointed.
We have not used your company before and will have reservations about using you again, I'm sorry to say.
We bought an eye and a heart to explore their potential use for ultrasound teaching. We will need to set them in gelatine. Too early to know if this will work for training though.
The people at Darwin Biological are great to deal with and we will buy more.

Excellent service, rapidly delivered. Will use again.
Wanted a delivery the next working day for my daughter college session. You delivered bang on time !!! Will defo be using again, I even emailed and they emailed me back quickly, thank you , Jenna
Very quick delivery and produced excellent colonies on nutrient agar.
Very happy with the kidneys but not with the delivery. I paid for 'next day delivery' but it was actually three days before they arrived.
Dear Graeme, Thank you for letting us know, I've looked on the tracking and you are indeed correct that Royal Mail took 2 days to deliver. I have now submitted a claim to RM and will email you a credit note for your postage costs. Kind regards, Meg
Nice sterile loops, for me much easier than having to flame/heat the same loop dozens of times.
