Each Test Paper variant is tailored for its intended purpose relevant specific areas of science or laboratory work. These are used in fields such as chemistry, biochemistry, nutrition, environmental science, etc. 

  1. Ascorbic Acid Test Paper:  Used for qualitative analysis of the presence or concentration of ascorbic acid (Vitamin C) in a solution
  2. Cobalt Chloride Test Paper: Can accurately identify the level of moisture present with a humidity level of 50% or higher
  3. Congo Red Test Paper: Used to test narrow-range acidic solutions for metal plating where pH values are very low (pH 1.0-3.0)
  4. Fluoride Red Test Paper: Detects Fluoride in steps of 0, 10, 25, 50, and 100ppm. The tested solution must have a pH of 0.5.
  5. Lipid / Fat Test Paper: Detects the presence of Lipids: Fats, Oils, Waxes. This may include hydrophobic molecules, sterols, and fat-soluble vitamins, including Vitamins A, D, E, and K, as well as Cholesterol.
  6. Glucose Test Paper: Detects 0.1 – 2.0% glucose. This tool is ideal for determining glucose levels in experiments involving osmosis and diffusion, as well as educational urine analysis and food science studies. 
  7. Lead Acetate Test Paper: Detects Hydrogen Sulfide in water in concentrations as low as 5ppm
  8.  High-Level QAC Test Strip: The High-Level QAC Test Strip (Quaternary Ammonium Compounds) measures the range of 1-1500 ppm in increments of 200, 400, 750, 1000 and 1500 ppm, and gives results in just seconds. Check for higher levels of QAC when testing stronger solutions that kill pathogenic organisms, as opposed to testing for residual QAC with our Low Level QAC test strip, or our standard QAC Quick Response Test Strip.

I wouldn’t recommend this for strong chewers.
Color: Orange, Color: Orange
Is it fun? Sure. Was it easy to charge and set up? Yep. That being said, this toy kind of fell flat for me. It really didn’t do any big movements once charged that I expected it to, so that was a bummer. I initially got it for my dog, but my cats were more interested in this than my dog was. The battery does seem to last a long time and the motor is pretty quiet. I WOULD NOT recommend this toy for strong chewers as the material for this is a foam rubber and I don’t think it’s durable enough for strong chewers. While the material makes this ball extremely lightweight for more movement, a strong chewer would have this disintegrated in five minutes flat. My Dog is a super strong chewer. I don’t think I would feel comfortable leaving him unattended with this because I know he would destroy it.

Well-designed and quiet, but didn’t keep my dog interested
Color: Blue
My dog was interested in this at first, but she would lose interest after a few minutes and move on. I do like that it’s quieter than the hard plastic ball toys, and the charge lasts well. The internal charging port that twists closed is also a nice design feature. That said, it will occasionally turn on by itself, which can be a little surprising. Overall, it has some nice features, but it just didn’t keep my dog engaged.

Good - for a few hours
Color: Blue, Color: Blue
Concept is fantastic. Dog loved it. Problem is that she figured out how to open it within two hours of play. The robot core, alas, did not survive. In the photo, you see a tooth went cleanly into the button and that was the end of the toy.
