The order was sent to the wrong Post Office sorting depot. As a result, the pond water I received isn’t in optimum condition, owing to delivery delay. There is no visible sign of minute invertebrate life, eg water flees, or other, making the order unfit for purpose. I’m attempting to start a natural aquatic environment from scratch. The invertebrates would have kickstarted that process.
They seem fine, there's not much to say about an agar plate.
Just wish you could get packs of 5 instead of 10, or even singularly wrapped
inside the bag they come in.
The growth medium arrived in good quality. It's easy to use following the guide provided. It's worth noting that one tube of solution is colourless, while the other one is slightly pale pink which may not be easily observed on the photos online.
The algae arrived were in good quality and in adequate concentration which can be used for experiment right away. It offers flexibility without the need to grow it first before use. Very good.
Easy to navigate website & excellent service ~ the third or fourth time I’ve ordered from Darwin Biological and would happily use many more times 👍
Package arrived quickly and the slides are perfect- thankyou
I’m a returning customer to Darwin.
Like supporting smaller suppliers, but in this case there is no downside in doing so.
Shipment is super fast and packed in reused boxes and even the paper for the invoice is on raw unbleached paper.
Kudos to their ethos.
The quality of the daphnia we received was very poor. I ordered 6 bags and there was barley enough to cover 1 class. I have had to order more from Blades but we will probably have to cancel some classes this week as we don't have enough.
Thank you so much for your review and massive apologies for the below standard daphnia recieved. Following your feedback, we have now reassessed how we package Daphnia on hot days, as it appears they have perished in transit due to the heat. Going forward, thermal packaging and cool packs will be utilised to ensure this doesn't happen again. We really do appreciate the feedback and hope that you'll use us again in the future. In the meantime we will arrange a full credit as well as a discount off your next order.
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.
