- Ascorbic Acid Test Paper: Used for qualitative analysis of the presence or concentration of ascorbic acid (Vitamin C) in a solution
- Cobalt Chloride Test Paper: Can accurately identify the level of moisture present with a humidity level of 50% or higher
- 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)
- 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.
- 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.
- 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.
- Lead Acetate Test Paper: Detects Hydrogen Sulfide in water in concentrations as low as 5ppm
- 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.

Fit perfectly!
The only complaint was they are shipped rolled up. Have to let them set out in the sun all day to flatten out. They're not rubber! More like a WeatherTech floor mats in a vehicle. Had plastic rivets to mount them to the floor, but wasn't drilling holes in a brand new buggy......

I was kind of skeptical to purchase this grille but ended up pulling the trigger on it , installation was not that hard, the hardest part is to swap the camera attachment to the non camera one , after that everything was a breeze, looks great and the material quality is no different from oem, will do another review after couple of months to give more info on the durability and paint fading ( if there’s any, hope not)

Instantly Changes The Look Of Your G20
Style: Gloss Black Single Slat, Size: G20（2019-2022）
Another great Amazon buy. Don't let the price or the crazy brand name keep you away. When I took the OEM grill off and compared it to this, it was pretty much spot on. All the clips are located in the right place, fits nice & snug and looks great. The most trouble I had was figuring out how to insert the front camera delete. There are no directions or videos explaining it. Once I concluded there's only one logical direction, I held my breath and applied the force that was needed to snap it into place. After that, it was a breeze (thanks to an unaffiliated YouTube video). Time will tell if it holds up (didn't like the other review that showed paint feeling off after a few weeks; not sure what that's about). If mine does the same, I'll surely update my review. For now, Highly Recommended.

As many things made in China you can't expect not to do anything to them. I had to cut or shave off a bit on the clips to make it work. end results put a smile on my face. Still worth the effort. Just keep that in mind or they will fall off.
