Innovating Science Forensic Chemistry of Blood Types Kit, IS9008

I used it in my Human A&P class and worked out amazingly. My students and I enjoyed this product. 10/10 would recommend!

Firstly, I could not find a link to contact the manufacturer directly regarding this product, otherwise I would have. The seller was listed as Amazon anyway, not Aldon or Innovating Science...???I've used ABO/Rh kits for my high school forensics class before and this is low quality in my opinion. The 4 simulated blood types look quite different, so you could see which 2 are a match without even doing the experiment. This could give students false impressions that different ABO/Rh types appear very different. My biggest issue though is that 2 of the anti-sera and one of the simulated bloods have some brown flocculant matter floating around in them. Mold? Bacteria? Either way it's gross. The printed materials and student masters are fair. Not great, not bad. Fair.Despite the contamination, the simulated bloods do agglutinate the way they're supposed to, so technically the product does work. But the poor product quality and spoilage lead me to give this product no more than 2 stars. I'd be very hesitant to order this brand again.
