## Overview

The Innovating Science Qualitative Coliform Test Kit offers 25 lactose test tubes to detect coliform bacteria through a simple color change after 24-48 hours incubation. Ideal for STEM education, it provides hands-on learning with clear visual results and includes safety instructions, making it perfect for students aged 13 and up under adult supervision.

## Description

Innovating Science chemistry kit is used to detect the presence of coliform bacteria, and has an activity for adding a small amount of collected water to a sample tube, incubating it for 24 to 48 hours, and observing results; a color change indicates the presence of coliforms. The kit has materials to perform 25 tests for hands-on learning, and includes an instructions and material safety data sheet (MSDS) packet for product information and handling procedures. The kit is suitable for age 13 and older with adult supervision, and is not subject to Department of Transportation (DOT) shipping restrictions.Science education products incorporate applied math and science principles into classroom and homeschool-based projects. Teachers in pre-K, elementary, and secondary classrooms use science education kits and products alongside science, technology, engineering, and math (STEM) curriculum to demonstrate STEM concepts and real-world applications through hands-on activities. Science education projects include a broad range of activities, such as practical experiments in engineering, aeronautics, robotics, energy, chemistry, physics, biology, and geology.Innovating Science products, manufactured by Aldon Corporation, include educational kits for the chemistry, life science, green chemistry, advanced placement chemistry, and forensic fields. Aldon Corporation was founded in 1964, and is headquartered in Avon, NY.What’s in the Box?(25) lactose tubesInstructions and material safety data sheet (MSDS) packet

Review: Used successfully in my daughter's middle-school science project - My daughter used this product for her middle-school science project, to detect coliform bacteria in the Hillsborough River in Florida. The product worked quite well. When 1 mL of river water was added to the test tubes, the liquid in the tubes turned from red/pink to yellow in about 48 hours (incubated at room temperature, nothing special required for incubation). The results were unambiguous: the yellow color is very easily distinguished from the red so there is no question as to what constitutes a positive or negative result. River water that my daughter treated with chlorine or with hydrogen peroxide did not cause a color change, indicating that the chlorine and the peroxide effectively killed the coliform bacteria in the river water. Results were reproducible -- replicates all behaved the same. Here are a few minor drawbacks. (1) We bought two boxes of these, with 25 tubes in each box; 1 of the 50 tubes did not have the proper volume of broth in it, so we could not use it. But 49 out of 50 tubes were fine. (2) When we treated river water with copper sulfate, and then added it to the tube, the broth *immediately* turned from red to yellow, without any incubation needed. This indicates some sort of interference or "false positive" caused by the copper sulfate. It might be that the copper sulfate caused bacterial cells to lyse, releasing the enzymes that interact with the broth? -- that is just a guess, I do not know enough microbiology to know if I am correct, could be way off. But anyway, don't use this product if you are treating your water with copper sulfate. (3) The test is qualitative only, not quantitative. It will not tell you how many coliforms are in the water. I guess if we knew how to dilute the river water and run multiple tests, we could probably get a "most probable number" of coliforms in the water, but that is way beyond a middle-school science project. I would say that this product is very effective and an excellent value for what it is intended to do. You have to be willing to wait 24-48 hours for incubation, and you won't get a quantitative result, but still it worked just fine for my daughter's school project.
Review: Poor quality control - My first order worked perfectly. My second order arrived with different amounts of liquid in each vial, and a variety of colors ranging from yellow to orange to pink to red. I could not use the second order at all. Good product when it works, but don't count on a good batch.

### ⭐ Poor quality control
*by Z***H on March 10, 2019*

### ⭐⭐⭐⭐ Rainwater testing -- worked for me!
*by J***F on March 26, 2020*

I use these to test my rainwater purification system. The various 1 or 2 test kits available become prohibitively expensive -- ~$10/sample on the average -- so I thought I'd give these a try. Simply put, they work for my purpose. Samples from each of four tanks soon after a rain fill showed bacteria (as expected), and water out of the kitchen faucet post-purification remained red (no bacteria, as expected). Just what I want to know. I took off one star because out of 50 tubes, 3 or 4 were grossly underfilled and one had already changed color to yellow when I received it. Still a good value for my purposes.
