Scenedesmus quadricauda, is a quick growing green algae ideal for pollution, eutrophication and photosynthesis investigations, such as the popular 'algae wrapped in jelly balls' experiment (See SAPS' website for free resources, including a post-16 version, video and support). Scenedesmus is an excellent example of a typical planktonic algae, they are non-motile and consist of 2 to 4 cells arranged in a row.

Darwin Biological's algae and protozoa samples are produced in partnership with the Culture Collection of Algae & Protozoa (CCAP) and are only available for UK schools and colleges to purchase. Please visit https://www.ccap.ac.uk/ to purchase if you are a university or commercial customer, or are outside of the UK.
This Scenedesmus culture is also available from the National Centre for Biotechnology Education (NCBE) based at the University of Reading as part of their Photosynthesis Kit, developed with SAPS (Science & Plants for Schools).
If you already have the kit and just require replacement algae, then this is the product for you! We recommend you purchase the 30ml bottle, it will take 2-3 weeks to grow to the needed quantity so please order in plenty of time.
The product arrived the next day, well wrapped. I have tried making a batch myself with no success. Lovely staff member said another school had bought a bigger bottle and just used that. Bought 100ml bottle and so far only used 15ml. Not sure how many hundreds I have made. Quite pale balls and they will be used next week for the practicals. Really prompt service via chat, telephone and email. Thanks
Our order arrived very promptly - we had not had much success in the past growing algae in the laboratory. We immobilised some of the Spenedesmus as soon as it arrived and it worked perfectly for the SAPS photosynthesis experiment.
Quality of algae was excellent. However arrived disappointingly by Royal Mail a day late . I will definitely order this again and allow an earlier receipt date.
Very speedy delivery of algae ready for our algal balls practical. Was especially pleased with the plastic free packaging, wish other suppliers would consider this too. Will certainly be using Darwin again.
From my initial phone enquiry through to online ordering and next day delivery I can't fault Darwin Biological. Excellent product and excellent service. The "icing on the cake" for me was that everything arrived in sustainably resourced packaging without the layers of plastic that so many suppliers insist on!
