- 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.

Buddy filled diesel skid steer with automotive gas engine oil. Used this to help.
We all know that guy who will buy a $65,000 machine and then only service it once a year with the cheapest oil on the shelf from Rural King or some other place with ultra cheap, home branded, questionably quality oil. Yep. That is my good buddy.
So I go to the shop a couple weeks back and he is re-filling the skid steer engine with some ultra cheap, totally not to spec, gas engine oil. I question him and he states that it is perfect oil for the machine being 5W-30. I ask him if it meets the SAE ratings for the diesel, he repeats back that yep... it is 5W-30. So I go grab his New Holland book (C232 track skid steer) and look up the oil requirements, then I look at this junk oil, and I try to explain to him the SAE designations on the back of the bottle and the SAE requirements in the book. He looks at me like I have 3 heads and repeats that it is 5W-30, it is totally good. Someone.... kill me please! He has no clue what I am trying to explain.
So I couldn't sleep knowing what he is doing, and I ran to Amazon to see if I can at least get zinc to add to the wrong oil and try to help the cam followers and rockers survive this next year. I found this. I ordered a few bottles and had them shipped to his shop, and I explained to him that these need to be dumped in to at least make an attempt in not prematurely wear the engine that likely is worth $20,000 or more!
So the real question is, will he actually dump these into the machine, or will he toss them on a shelf never to be seen again? We may never know. But I bet next winter he will once again shop for the cheapest oil on earth to put in a machine that costs as much as some peoples home. He is who he is, you can never change that.

High quality replacement clips. Highly recommend.
I used these when replacing the headlight assemblies on my 2011 Honda CR-V. A few clips were already missing before I even started taking the bumper off, and of course a couple more didn’t survive the job.
These fit perfectly and snapped right in with no issues. If you’re missing clips or break some while doing a repair, these are a simple fix that gets everything secured again. Very good deal.

Mostly usable parts
Good fit, work well, but some sizes too small for my car, useless.
