About Us

Darwin Biological offer great service and would highly recommend.

The sample looked full of life, put a wild life pond on my allotment started from fresh looking forward to seeing life in the pond.

The samples arrived in time, were healthy and i woke them up in less than 1 day, I’m working from home but just in 3 days, so many interesting observations!

Arrived on time very well packaged got them for my wildlife pond and to set up my own breeding culture had them a couple of weeks now and doing really well seem to be breeding in the tank don’t know what they’re doing in the pond pleased with my purchase

It arrived on time, and the product was easy to use. Additionally, the delivery was hassle-free.

Products were delivered promptly and were of excellent quality. The ordering process, payment, and shipment tracking were easy to navigate.

Locusts are very happy with the bran.

This product was delivered to us so quickly the service was fantastic, the packaging was flawless every attention to detail had been given to the super speedy, safe delivery of E Coli K12 that has worked perfectly.
I accidently found this company looking for a quick delivery Darwin Biologicals were able to dispatch immediately allowing us to have next day delivery The usual four companies that we have used in the past all had a two week delivery.
We are over the moon with the impeccable service.
Thank you very much

I ordered K. rosea and a few other gram positive bacteria, all the strains arrived promptly within a couple of days of placing the order, and they all looked healthy. My lab and I are very happy with the speed and convenience of purchasing strains from Darwin Biological, we would be happy to buy more strains from them if any new ones become available on their store

I ordered a frozen rat from Darwin Biological for a school's open evening dissection, and I was really impressed with both the product and the service. The specimen was a good size and arrived in excellent condition. It was well frozen, intact, and with no damage. My highlight was the packaging, which was particularly noteworthy, using recycled wool for insulation... I really appreciated from a sustainability perspective. I also had a very tight delivery window, and after contacting customer service, the team went above and beyond to ensure it arrived on time, which made a big difference!
Overall, a very positive experience. I would definitely order from Darwin Biological again and highly recommend them :)

Fast delivery, decent price and selection of bacterial cultures. Would recommend and will be using again.

Excellent product. Lots to see!

Arrived sealed and in perfect condition in lotta of package peanuts. I am yet to use, but it looks brilliant
