Forensic Chemistry of Blood Typing: Identifying and Classifying Blood - Distance Learning Kit - Innovating Science

Purchased for my forensic science high school class (homeschool co-op). Very useful. Arrived as promised. Would buy again . Good value

Doesn’t Coagulate. Don’t recommend

Either the synthetic blood mixtures used, or the anti-B and Rh reagent, were no longer viable, as only the anti-A reagent produced any reaction. I have used similar kits with my classes in the past, and this is my first time not getting the expected results. I review the procedure included with the kit before and after to verify it was not a procedural error, and all monitored my students to ensure they followed instructions. I also did a test sample myself and none of us got the proper results.

While I have yet to use the product I have used these kits before and have bought them from other companies. I wanted to give this company a chance to win my business. Clearly and I mean clearly they fell short. Every bottle of solution was less than a quarter full. If I am lucky I will be able to let one lab team do one experiment. Looks Like I will be returning to my previous company for these products. A bottle of solution should be just that "a bottle OF solution" not a failed attempt at fulfilling an order. Good Luck with selling this product to other people especially when they see an empty bottle.

Only one of the four fake blood samples produced a reaction that indicated a blood type other than O-. I assume that each sample should have produced a different result, so it stands to reason that some (or all) of the sera are not functioning properly. We performed this lab with this brand of kit purchased a few months ago without any issue. So, I feel like we have received a faulty kit this time.
