This took a little longer to come than the other products we purchased ,but it was very healthy and worked well in the bubbling experiment.
Delivered safely and put in one. Won’t know how effective till later but pleased with order
Delivery was very quick and the heart was a very good specimen, fully intact and ideal for demonstration use on open morning.
Really happy, worked great. Fast delivery. Buy this product from here every year because I know it works.
Easy to order. Delivery very fast and nice sample. Will definitely order again
Delay in writing review as I wanted the teachers feed back on the fish heads. From a technician's point of view, so easy to shop here for fish heads. Arrived in an extremely timely manner in great condition and brilliant recycled packaging.
Great dissection material and yes we have stunk out the whole department!.
E. coli growing well. Thank you.
They are suitable to store in fridge for longer period. Individually packed and ready to use from your lab all the time.
Speedy delivery and very high quality. Would highly recommend
These arrived in perfect condition and were great for our students.
Excellent service. The pooter is ideal for collecting micro moths. I would recommend Darwin Biological as a company.
Hi again,
I happily award five stars, as your level of Customer Care and courteousness during your call, (following my last review), deserves applause. Now though, onto the nitty-gritty …. Would you believe that, your second delivery of pond water was just as devoid of ‘visible life forms’ as the first. I’m truly not laying the blame at your feet, simply that, it must have something to do with oxygen depletion - that’s my guess. Just as a suggestion, I reckon a simple, secure ‘fit for purpose’ polythene bag, (like the ones a goldfish is carried in), and some air pumped would be a good alternative.
I’m NOT requesting a refund, as I spent hardly anything.
All the best
Jeanette
Dear Jeanette,
Firstly I'm very pleased you had a good experience of our customer services, I'll pass your compliment on!
Regarding our pond samples, when viewed under a microscope, they contain a multitude of algae and protozoa. As they are a natural sample we can't guarantee specific species or the presence of invertebrates, but can assure you that upon dispatch they are teeming with microscopic life.
Many thanks,
Meg
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.
